Introduction

All global population is currently facing a very dreadful situation of global health emergency in the form COVID-19 which is imparting a great burden over all health care systems & economy of all affected countries. WHO has declared it as a pandemic state. COVID-19 is a type of airborne disease which highly contagious & attacks over respiratory system. Though statics of these diseases shows its high incidence rate, high occurrence, fast replication & great extent of spreading nature & high mortality rate ; till date ,there is no any effective remedy in the form medicine or vaccine is developed in contemporary science to combat over this situation. Therefore , prevention remains the unique way to overcome such pandemic state. It is the need of hour to develop a safe and effective treatment approach in alternative science i.e. Ayurveda for management & prevention of this type of infection. The concept of prevention of disease is the unique specificity of Ayurveda which is elaborated over reams & reams of pages of Ayurveda in a very beautiful manner. It plays an imperative role in elaborating this concept of communicable diseases.

As prevention is the single option to fight with this dreadful situation & immunity of the individual plays key role against this fight. Because prolonged weakened immune system give rise a greater susceptibility to various infections especially related with respiratory system, herpes and fungal infections. It is a very disappointing thing that as a result of faulty & fast lifestyle in this era; improper diet, lack of exercise, stress, low quality of food grains, crowd population, unhygienic conditions & global warming ; overall health status of people become poor & chances of getting susceptible to such communicable diseases is also at high level. However, application of various preventative aspects of Ayurveda based on its fundamental principles like Sadvrutta, Panchkarma,Dincharya,Rutuchraya successfully empowers the person to fight against this virus.

Through this paper, sincere efforts are done to compile certain preventive as well immune boosting modalities mentioned in the Ayurvedic sculptures.

A comprehensive literature search related with various clinical entities involved with Pranavaha Srotas(Respiratory System) i.e. disorders of ShwAsanavaha Sansthana, causative factors, various regimes for prevention as well as remedies for treatment for such ailments like COVID-19 was done using all available Ayurvedic compendium e.g. e- Samhita and e Nighantu, full research articles from various databases such as Google scholars, PubMed, Shodhaganga, multiple P.G. & Ph.D. dissertations from different institutes till March 2020. For the study, several related articles were referred and an attempt has done to find out concerened information.

OBSERVATIONS & RESULTS

Information collected after extensive review regarding various treatment regimes in Ayurveda which can be used integratively for prevention & management of COVID-19.However, this information was observed in scattered from under different entities such as holistic approach of lifestyle i.e.Dincharya & Ritucharya, importance of diet for immunity, Vyayama (Indoor & outdoor exercises), Ayurvedic Herbs, drugs & formulations according to symptomatic management & immunity boosting purpose, useful Upakrama (therapies), Rasayana Chikitsa (herbs & different formulations), Yoga practices (Asanas,meditation ), Spiritual aspect, Dhoopana therapy (different formulations & indications according to different Acharyas), Ayurvedic hand sanitizer and nasal spray with their useful drugs. These all concept will be elaborated one by one as follows

There are ample references of various causative factors vitiating of Pranavaha & Rasavaha Strotas i.e. respiratory system & causative pathological factors causing Vata-Kapahaja Jwara described in various Ayurvedic compendium play important role in the pathogenesis of various airborne communicable diseases (Charak Samhita of Agnivesha, 2017; Vidyadhar & Dutt, 2017). Symptoms of airborne communicable diseases such as COVID-19 have similarity with symptoms of Aoupasargic Roga(diseases which are communicable in nature), Janpadohwanasa in Ayurveda & Vata-Kapahaja Jwara which are caused due to vitiation of some factors such as air, water, location and seasons (Kaishika & Madhavnidan, 2005; Sharma & Kalpasthana, 2005; Sharma, 2005; Trikamaji, 2011).

Treatment strategies in Ayurveda

As transmission of Corona virus is affected by multiple factors, including environmental factor, host behavior, host defense mechanisms (the body with weakened immune system are more prone) , and virus infectivity. All these factors should be taken into consideration while deciding prevention & treatment plan of such conditions. Among them, only host behavior, host defense mechanisms lies within boundaries of human efforts. Three types of strategies i.e. Daivayayapashraya,Yuktivayapashraya & Satavavajaya are advised by Ancient Acharyas for management of such communicable diseases under their different components. However, it is a noteworthy thing that most strategies among them are preventive in nature.

Concept of Holistic lifestyle i.e.Dincharya & Ritucharya

In Ayurveda, maintenance of good health of mankind is explored by balancing dynamic equation between man and his surrounding environment. As immunity plays an important role in communicable diseases & it can be maintained by adopting healthy lifestyle with the help of Dincharya & Rutucharya (Day & seasonal regime),exercise, proper diet. As there occurs specific physiological changes in body due to various diurnal & seasonal variation, significance of concept of adoption of both Dincharya & Rutucharya remains imperative to maintain equilibrium between internal environment (human body) & external factors (environment) by achieving harmony between Tridosha in the body.

Nowadays, severe disturbances in environmental pattern are occurred due to global warning & Mithya Yoga of Kala e.g.there occurs heavy raining in summer days i.e. called as Kala Vaishymya which badly affects over physiologiy of human body also. So it is very necessary to maintain hormony between Triodosha in body and in order to adopt it, becomes necessary to give emphasis over intake of proper diet. Appropriate diet & lifestyle should be adopted in such situation which is decribed in Rutu Sandhi Kala.

In such scenario, it becomes a need of hour to give specific attentions & to follow regulations strictly in context of specific diet, lifestyle modifications & useful procedures for detoxification which are recommended in Dinacharya & Rutucharya. As healthy diet is an important part of supporting a strong immune system, so planning of diet in covid Pandemic serves greater role. Considering the current need of proper diet planning, following diet suggestions based on the fundamental principles of Ayurveda are given as follows.

• Maintain optimum hydration of body by drinking plenty of water to help body to eliminate waste metabolic products from body through urine & sweat which helps to build good immunity .

• Intake of balanced, healthy food in proper quantity at regular interval as per narrated in Ritucharya.

• Avoid Food which is heavy in digestion as well as high in salt ,sugar and fats.

• Prefer antioxidant herbs in food and laghu aahara e.g. Moong dal khichdi, Jowar roti, Cucumber, Cereals, pulses, whole grains, legumes, nuts.

• Judicious use of Spices such as ginger, garlic, turmeric, and capsaicin (from chili peppers) while preparation of curry, soups, stews, stir-frys, or salad dressings since such spices have multiple medicinal benefits of improvement in digestive health by kindling the agni & give tough fight against cold and infections by their properties e.g. antibiotic, anti-inflammatory and anti oxidant.

• Erratic eating should be avoided

Some home remedies such as herbal tea / decoction (prepared from Tulsi (Basil), Dalchini (Cinnamon), Kalimirch (Black pepper), Shunthi (Dry Ginger) and Munakka (Raisin) advised by Bhaishajya Ratnavali)& Milk medicated with Turmeric in order to improve immunity in pandemic state of COVID -19 can be suggested in addition to above recommendations.

Vyayama (Indoor & outdoor exercises)

Vyayama is the important aspect of Dincharya & Rutucharya. It is highly appreciated to maintain physical fitness or strength (Balavardhakala), to improve immunity, to increase in appetite (Agnivardhak) to make person engaged, cheerful (Manasprasankar) & enthusiastic. As in lock down period of COVID-19 pandemic, most of the persons are at home or doing work from home, so physical activity get reduced and as a result of that, multiple complaints such as indigestion, constipation,loss of appetite regarding digestive system get started. To overcome all these complaints, proper indoor exercise is the good treatment of choice. Due to regular exercise, Incresaed status of Agnidipti helps in increase in food intake with proper digestion and directly helps to provide proper nourishment to uttar-dhatuand so helps in increasing the immunity which is a key factor to fight against the Corona Virus.

Indoor exercises such as Surya Namaskara & Pranayama helps to improve in proper breathing techniques by providing optimum fresh air to lungs and increase oxygen supply to all the organs & helps to stimulate overall mechanism of the body. However , selection of type & duration of exercise should be decided on the basis of physical strength of person which may varies from person to person and season. Excessive strenuous exercise with prolonged duration is strictly contraindicated by ancient Acharya also, It should be done till appearance of sweating over forehead.

Role of Ayurvedic Herbs & Drugs

It a type of Yuktivyapashraya Chikitsa till date; no any drug has specific claim to treat COVID 19,therefore, exploration of traditional remedies are highly needed in current scenario. Vata-kapha Jwaraghna Chikitsa is expected here in the form of Amapachaaka & Jwaraghna & Vatanulomana Chikitsa. Various formulations in Shwasa ,Kasa , Hikka , Rajyakshma can be used here as per nature of symptoms & type of pathology involved. However , constitution , Sharir, Nidana, Desha, Kala of person patient should be taken in to consideration before administration of these drugs.

Herbs such, Ashwagandha, Avla, Ashwatha, Brahmi, Dhanyak, Rason, Guduchi, Haridra,Kutaki, Kantakari, Marich ,Nimba, Pudina, Pippali, Shalla, Sunthi, Tulsi, Twak, Vasa ,Sunthi are recommended by Ayurveda for ailments like COVID -19 which are originated from Vata & Kapha. All these drugs are Antioxidants, anti-inflammatory, Immunomodulator, anitiviral, antimicrobial & Vatakaphahar in nature.

Regular consumption of water medicated with Sunthi,Tulasi ,Dhanyaka, Haridra ,Rasona can be advised to improve digestion & to boost immunity. Anti-inflammatory, antibacterial, antiseptic & antioxidants properties of above drugs are also useful to fortify digestive tract, relieve nausea, bloating and constipation. Milk medicated with herbs such as Rashon Ksheerpaka, Pippali Ksheerpaka are highly useful in fever.

As Haritaki (Termelia chebula ) is immuno modulator & Rasayan drug, therefore; administration of Haritaki is advised by Acharya in all seasons with specific Anupana under the head of Rutu Haritaki to maintain health. Treatment which can advised according to specific type of symptoms of communicable diseases are mentioned in Table 1 & various formulations useful in such diseases are narrated in Table 2.

Upakrama (Therapies)

Upakrama (different putative therapies) are integral part of Apakarshana Chikitsa i.e. to remove the source of infection completely with breaking of main root of pathology. As Apakarshana Chikitsa is mentioned by Acharya Charaka for management of Janpadodhwansa Vyadhi. Rational & judicious use of Karma Panchavidham i.e. Panchakarma in the form of emesis, purgation, enema,nasal instillation and Rasayana Chikitsa according to season at regular interval yearly are strongly recommended by Acharya charak, Sushrut and Vagbhaa in the context of Janpadodhwnsaa Vyadhi or pandemic situation such as COVID -19 for prevention purpose.

Even seasonal application of these different putative therapy prior Rasayana is considered as mandatory protocol in order to yield optimum benefits of Rasayana therapy which is the main tool to mainatain immunity (Atrideva, Hrudayam, Vagbhata, Edn, & Prakashan, 2009). For this purpose, Haritakyadi Yoga i.e.combination of Haritaki (Terminalia chebula),Saindhava lavana (rock salt), Amalaki (Emblicaofficinalis), Guda (jiggery),Vacha (Acoruscalamus),Vidanga(Embelia ribes), Haridra (Turmeric), Pippali (Piper longum), Shunti( Ginger) is advised by Acharya Charaka. Different types of Upakrama or procedures useul for various symptoms in COVID-19 are given in Table 3 with their drugs & their utility.

Concept of Rasayana

Rasayana is the specific form of treatment in Ayurveda which works on fundamental aspect of organs i.e. Dhatus, Agni and Srotas by nourishing Rasaraktadi Dhatus(the seven basic tissues) with the help of its properties such as Anti-ageing, immunity boosters or Immunomodulator, Adaptogenic(regulator which increases the ability of an organism to adapt to environmental factors and to avoid damage from such factors), Antioxidant, nootropic, antistress properties especially described by Charak (Paradkar, Of, Vagbhata, Rasayanvidhiadhyaya, & Edn, 2009). These common properties of Rasayan drugs are vividly explained throut the Ayurvedic literature (Tripathi & Dutt, 2005).

Main intension of Rasayana therapy which is beautifully ellabortaed in Ashtang Ayurveda reaffirms its use to keep intact healthy status of body by enhancing natural defence system. Rejuvenation and Revitalization actions of the Rasayana drugs to enhance immune system as well to increase longevity of life is very well described across various Ayurvedic scriptures. Regular healthy practices of Rasayana can be applied in day to day clinical practice to offer an effective tool for the prevention & management of communicable diseases.

Diet (Aahara), Medicines (Aushadha) & behavioral therapy (Achara Rasayana) are three basic pillars of this Rasayana therapy. All of these perform their action of immunity building by doing purification of body and mind. Among different types of Rasayana, Vatatapik Rasayana can be used for treatment of communicable disease according to Aacharya Charaka since such Rasayan are easy for application & having minimal restrictions. Among 4 types of Kamya Rasayana given by Charaka, Pranakamya & Ayushkamya are useful for covid pandemic. The role of Rasayana in communicable diaseses can be justified by Sharangadhara who quoted that Rasayana is useful in the prevention of diseases due to old age. Various Rasayana Yogas & Ayurvedic herbs useful for COVID-19 are described in Table 4.

Behavioural therapy in Rasayana ( Achara Rasayan)

Sadvrutta i.e. code of conduct is the essential part of Dincharya & a type of Achara Rasayana. It plays crucial in prevention of communicable diseases. Achara Rasayana which is a type of Rasayan therapy i.e. specific code of conduct is beautifully expressed by Charaka in the form of regular truthful talk, avoidance of addiction such as alcohol, smoking etc., maintenance of celibacy, maintenance of calmness of mind by indulging itself in creative activities, pleasant talking, maintenance of hygiene by avoiding eating in unclean utensil or avoid eat dirty & stale meal served by the unclean food server at unhygienic; cowded & public like streets, places of worship, near water sources, hospitals, parks, schools etc., regular bathing daily twice, regular cutting of hairs & shaving, wearing full clean clothes, carrying of auspicious herbs and gems on hand, applying daily oil to head, ear, nose feet(Abhyanga), purifying home with Dhoopana, avoid scraping, brooming roof (Sharma, Samhita, & Sushruta, 2005), stability in thoughts, straight forward actions with courage, regular indulging in charity works, application of regular practice of penance, respecting older persons, maintenannace of self control, following balanced & healthy diet regime by preventing incompatible food.

Sadvritta works more widely and effectively than immunization with respect to prevention from communicable diseases as it is cheap and easy to follow. Physical health by procedure called as Achar Rasayan which gives all qualities of rasayan ^. Any person can prevent himself from disease & attain good health by applying sadvritta related with Ahara, Vyavyay & hygiene. Table 5 shows for Rasayan for COVID-19.

Role of Yoga practices

Yoga practices are a non-pharmacological form of preventative treatment which reduces negative onslaught of stress which has bad impact on the immune system and decreases susceptibility after prolonged exposure to causative factors. It compromises various practices such as Asana (physical postures) & Pranyama (controlled and slow breathing), Yama and Niyama (part of Sadvrutta),Shat karma (cleansing techniques), relaxation techniques of meditation & sermons on Yoga philosophy. Various useful Asanas useful for COVID-19 with their possible therapeutic effects are given inTable 6.

Among different Asanas, some Asanas offers immunity ,improves lungs function or have dual effects as follows so should be practiced on daily basis.These special techniques of breathing & Surya Namaskara increases immunity & strengthened the Pranavaha Strotas (respiratory system), Rasvaha Strotas (lymphatic system), potentaite physical strength to manintain the Ojas, Teja, Prana,increases the Lung Compilance and also improves the cardiac output. It induces all these effects by balancing between body & mind. It can be effectively used as mind body medicine. It is a eternal and holistic model of health and healing of body very fastly. Various Yogic practices in the form of Pranayama & Suryanamaskara, Asana plays very crucial to promote and improve respiratory and cardiovascular function as well their immunity. Due to regular habit of such exercises, there is increase in vigor & vitality to prevent such infection or if caused then to avoid complications such as respiratory distress. These different Yoga Practices stimulates the Digestive fire & metabolism of the body & mental strength to fight against different diaseases.

Considering these multiple benefits of Yoga therapy, different practices of Yoga can be considered as a complementary therapy to manage such ailments during quarantine to improve immunity & to keep persons engaged & refreshing. It can be applied in period of corona pandemic as indoor activity to prevent or reduce physical or mental stress. These are also helpful to maintain physical fitness during lock down period.

Spiritual aspect for COVID -19 according to Ayurveda

Spiritual aspect of Ayurveda for communicable diseases again reflects through Satwavijaya Chikitsa & Daivavyapashraya Chikitsa which are described by Acharya Charaka as one of modaility in Janpadodhwnasa Vyadhi (Kaashinath & Chaturvedi, 2009; Kashinath & Chaturvedi, 2009).

Devaviprashya, this is also a Sukshma Chikitsa having nonpharmacological action which includes Homa, Japa, Doom Doom Masvanadyay e.g. Clapping over Marma Of Hands (Heart, Kidney, Lungs to convey impulse efficiently to inner vital organs .Homa, Havana, Yagya i.e. medicated fumigation /Dhoopana are vividly explained in Yajurveda & Atharvaveda. Practices of Dhoopana twice a day that is at morning and evening to attain the spiritual enlightment mental peace, purification of mind and environment is advocated in Yajurveda (Ahlawat & Sharma, 2019; Anataram, 2018). In Durga Sapatashati written by Markadeya Rushi, a whole chapter is allotted to describe a type positive energy to destroy causative factors of communicable diseases which have multiplication tendency & spreading nature. A whole chapter is devoted for Havana Vidhi by Harita & Sanidvarga & various aromatic drugs are described in it. Specific mantras for specific drugs for specific Nakshatra are also mentioned (Harihara, 2009).

Mantra especially Rama Rakshastrotra given by Kaushik Rishi, Gayatrijwara Strotra, Purusha Sukta, Vishnu Shastra. According to Acharya Charak Mantra Chikitsa is very beneficial in these conditions this is also accepted by the modern science as a raga therapy. Regular Cition of Japa is mentioned as a part of Achar Rasayana by Charaka Samhita for purification of mind, to develop positive energy & to strengthen mental stability.

Concept of Dhoopana

Dhoopana is the procedure nothing but fumigation with Ayurvedic herbs to prevent or reduce contamination of air. Main role of Dhoopana is to check over the spreading nature of pathogens & it is chiefly indicated for sterilization or fumigation of operation theatres ,labour theatres.

It is also indicated in clinical conditions which are transmitted by sneezing, breathing, talking, coughing , raising of dust , spraying of liquid , toilet flushing or any activities which generate aerosol particles or droplets (Hart, M, & Chiarellol, 2007).. As airborne pollutants could even act as a carrier of the new coronavirus and allow it to survive in the air attached to particulates for over 72 hours at temperatures of 22–25°C and relative humidity of 40–50% (Hall, Douglas, & Geiman, 1980).

As microbes or pathogens have generally microscopic structures & these are narrated under terms of Bhuta, Graha, Jantu Or Krimi. Dhoopana is the ideal regime to kill such pathogens & to prevent spreading of infectious diseases especially COVID -19 originated from them through contaminated air. The concept of Dhoopana is very well elaborated by various Acharyas especially By Sushruta & Kashyapa. Acharya Vagbhatta has mentioned Dhupan Karma (fumigation) of Vastra, Shayya in Sutrasthana.Acharya Kashyapa has mentioned 40 Dhupanyogas in Dhupakalpaadhyaya. Wide range of drugs are provided by them for different preventative & curative aspect with their exclusive methods of preparation of Dhupa. In Athravaveda , complete Sukta is devoted for Rakshoghana Karma.There are ample references of this Dhoopana karma with its detil narration under heads as types,indications ,instruments & various drugs useful for it (Hemraj, 2013).

Main actions & properties of Dhoopan Dravya are antimicrobial, antifungal, antiviral. Fumigation with the help of these drugs destroys worms & germs in environment.

In current scenario of dreadful outbreak, Gomaya (Cow dung & Vacha with Ghrita or Ghee along with Neema Patra should be added to do Dhoopana can be done due to their easy availability to fumigate places where prevention of the entry of pathogens is expected. Since Ghee used in Dhoopana Yogas helps in rapid combustion of cellulose of herbs and keeps the fire alight. As Antimicrobial (Bacillus and Pseudumonas) and Disinfectant Properties of Gomaya are proved by (Girija, 2013) that gomay showed the positive response in mycelia growth of plants pathogenic fungi which is also found as effective as penicillin and streptomycin in as per studies. Vacha has itself famous for its antimicrobial property. Useful different Dhoopana Yogas for sterilization of different articles with their ingredients according to different Acharyas are described in Table 7.

Concept of Ayurvedic hand sanitizer and nasal spray

Maintenance of Cleanliness is important componenet of Achara Rasayana to achieve sound status of health (Anant & Damodar, 1980). As hand is a type of Karmendriya Grahan or Dharana Karma (Tripathi Brahmanand). & very vulnerable to carry primary infection. Ayurvedic hand sanitizer and nasal spray are primarily intended to prevent primary mode of transmission of microbes and various nosocomial infections (Ravi, Pratibha, & Kolhapure, 2005). As transmission of COVID-19 takes place mainly through respiratory droplets or contact, it performs leading role to avoid exposure.It proves the important role of hand hyginene. Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using senitizers. This concept can be launched with preparation Ayurvedic sanitizers in the form of qwath (decotion), Phanta or Arka Kalpana with some Ayurvedic herbs having properties such as Rakhshoghna, Krumighna, Vishaghna, Kandughna, Kushthagna Dahaprashana (Vidyadhar et al., 2017).

Nimba (Azadirachta Indica), Tulsi (Ocimum Sanctum) ,Jambira, Nimbu (Citrus Limon) , Haridra, Daruharidra, Mahanimb, Vidang, Karanja, Nirgundi, Shirisha , Guduchi, Triphala, Aaraghwadh, Bilva, Kapithha, Jatamamsi, Arka, Nirmali, Sariva, Lavanga, Ghruta Kumari, Audumbar Saal have Krumighna, Vishaghna, Kushthaghna, Kandughna properties.Therefore, such drugs are highly recommended for the preparation of these Ayurvedic sanitizers. Gomutra Ark is added to increase the antimicrobial quality of this sanitizer.

Breathlessness, sneezing, nasal congestion, runny nose, sore throat etc are common complaints in COVID-19,Nasal Spray is useful for that. Drugs having properties of antiasthamatic, antihistamine, antiallergic Antibacterial and bronchodilator, Antitussive & muscle relaxant effects can be used for the preparation of same. In addition to these,drugs advised in respiratory ailments such Shwasa, Kasa, Hikka or herbs useful in Pulmonary Eosinophilia can be used for preparation of Herbal sanitizers & Ayurvedic nasal Sprasy.

Discussion

The concept of communicable disease along with the mode of spread has been elaborated in a beautiful manner by Acharya Charaka & Sushruta by stating different types of Krumi (Worm), Jantu (Insect ), Jantu (Virus),Graha ,Raksha (microscopic parasites) or vitiation of Air(Vayu), Water(Jala), Time(Kala) & Region(Desha) as causative factors for developing various communicable diseases like COVID-19.

Management approach of airborne communicable diseases like COVID-19 in modern science compromises mainly the controlling the source of infection & interruption of the route of transmission with different strategies as Immunization & conservative management. Among them, mainly prevention & specific treatment(rational use o appropriate antibiotics or antivirals, proper ventilation, shifting to room which have special air handling system are recommended

Ayurveda has greatly appreciated for prevention of any disease rather than its treatment. However, in Ayurveda, treatment strategies of such disorders are established on the base of three pillars i.e. Nidana Parivarjana ( avoidance of etiological factors), Apakarshana (complete elimination of disease causing morbid substances by purifying body with the help of Panchakarma), Prakriti Vighata (Rational use of medication, Rasayana Chikitsa, Sadvrittapalan). However, Ayurveda quotes that root cause analysis is considered as significant first and then appropriate treatment according to that will be preferred.

Through different modes of treatment & prevention, Ayurveda accepts the presence of micro - organism & most emphasis is given to maintain equilibrium of the internal environment so that to avoid multiplication of causative organism. For prevention, NidanaParivarjana in the form of Dhoopana, with Bhootanashak Dravyas(antimicrobials) has important role to remove causative factors by purifying the air. Prevention aspect of modern approach is justified by ancient science in the form of proper & strict conduction of Dinacharya & Ritucharya (specific daily & seasonal regimen), application of Sadvritta (good moral conducts) & Achararasayana; Ashtanga Yoga to keep harmony between internal environment of human body & external environmental factors.

As people with less immunity are more vulnerable for attacks of such communicable diseases vary easily. Therefore, Importance & role of diet is very crucial for management of COVID since diet is basic need for survival of human body & balanced, healthy diet always improve the immune system by building good nourishing tissues. Considering the rutu and the present environmental conditions, Physical and mental health, diet should be planned. Fruits, vegetables, cereals included in diet helps to maintain the health properly and they can feel light and further it help to proper digestion ,it also leads to burn fats, calorie, which will lead to healthy body and help to maintain to immunity as per previous articles.

Due to similarity in symptoms, causative pathological factors described in Samhita in context of Vatasleshmak Jwar,Shwasa, Kasa, Hikka, Pratikshaya can be taken into consideration during management of COVID-19

Utilization of Ayurvedic Herbs with drugs having properties e.g.antiviral , Antioxidants , immunomodulatory, antipyretics and brochodilators which strengthen the respiratory system and improving the immunity can be highly appreciated in conditions such as covid-19 (Vinay & Rajshri, 2015). All drugs such as Vasa , Brahmi, Shallaki, Haridra, Ashwatha, Tulsi, Kutaki, Pippali, Kantakari advised in Pranavaha Strotas Vyadhi which are anti-asthmatics & broncholytics in nature can be used here.

Concept of Rasayan is very important because there are more chances of survival of causative virus & potential of their rapid multiplication in body where status of immunity is grossly compromised which may lead to death or damage the particular organ or part of body. Application of immunomodulator drug in the form of Rasayana & antioxidant herbs should be recommended for new born baby or below 8-10 yrs child, too old people, Diabetic, Hypertension, Heart disease etc whose immune system is grososly compromised (Rakesh, 2019). Desired action of Rasayana drugs are to prevent diseases, to avoid recurrence of the disease and to impart strength to Pranvaha Strotas by enriching Rasa with the nutrients, improving digestive fire in GIT as well improving digestion at cellular level i.e. metabolic process, improving microcirculation at the level of strotas. Among various types of Rasayana, especially Kuti praveshik Acharya Rasayana acts as a catalyst for rejuvenating medicines. It also helps to resolve panic stage of population of affected area by any epidemics by improving mental status of person for optimistic thinking, relieving mental stress and physical strain, improving patience and tolerance capacity of them.

Role of Pradhamana or Shodhana Nasya in COVID -19 can be justified on the basis of opinion of Acharya Charaka as irritant medicines used in Pradhamana or Shodhana Nasya drags and removes the vitiated dosha immediately from respiratory tract through eyes, ears, Nose & throat. As most common route of transmission of the Covid Virus is Nose, eyes or mouth, administration of medicines in the form of nasya procedure, a protective media can be created , to prevent the entry of virus in body & to avoid effect of air pollutants on nasal as well as bronchial mucosa. Nadi Sweda in the form of Steam inhalation protects respiratory tract by different air pollutants & allergens responsible for airborne communicable diseases.

By means of these different Upakrama, person can keep distance form CORONA since these all Upakramas induces clear nasal and oral route and cure disease related to respiratory tract by decreasing Kapha Dosha.with improvement in immunity & efficiency of sense organ strongly. Appropriate use of Panchakarma and Rasayana along with Sadvrittapalan are also recommended strengthening the Agni to avoid Amavastha in body. (Atrideva et al., 2009; Trikamaji, 2011).

Dhoopana Karma explained in Ayurveda can be used for massive & local sterilization. Yagnya in the form of medicated Dhoopana was performed by the intension of mass hygiene. Various Dhoopana yoga in contagious disorders like viral fever, Jwara or Kustha suggests its antimicrobial activity. Almost all the Dhoopa ingredients have action of deodorant, antiseptic, insecticidal, anti pyretic, anti inflammatory etc. As Dhoopana Dravya have bacteriostatic or bactericidal, wormicidal, anti-inflammatory, antiseptic effect (L, 2013), massive sterilization can be achieved through use of Dhoopana by reducing the microbial load of the environment. Their volatile would be a distinct advantage in lowering microbial contamination in air and on difficult to reach surfaces. Therefore, the Dhoopana therapy can be used in Pandemics like COVID as it is invasive form of route of herbal drug administration to avoid further spread of contagious diseases through contaminated air.

Hand sanitizer and Nasal spray prepared with Qwath, Phant & Arka Kalpana with specific Ayurvedic drugs with above properties checks over transmission of pathogens from source of infection to hand and nose respceticvely.Medicines effective in Pranvaha Srotas diseases can be applied for the same purpose. Application of both these non-pharmacological interventions plays key role for prevention of COVID-19

In context of this era, Sadavruuta or Acharayana Rasayan, complete stay at home, follow Dincharya, Ritucharya,intake of warm water,maintenance of hygiene can be applicable in this outbreak of Corona Virus. Preventive aspect can be fulfilled by maintaining respiratory hygiene and cough etiquette with the help of covering mouth & nose with tissues or handkerchiefs while sneezing, coughing, by proper disposing such used items ,by washing hands with disinfectant regularly especially after contact with respiratory secretions ,by using gloves, maintaining specific distance while communicating directly Stressing hand hygiene, by avoiding visiting at public places which prevents exposure of causative factors of Janapada Dwamsa Vyadhi & checks over the transmission of infection. Such type of Sadvruutta should be followed strictly by patient, family members, visitors, employees, and care providers. Above broad spectrum regime of Sadavrutta planned for physical as well mental hygiene is a very cost effective & simple to follow.

In this way, integrative approach of Ayurveda can be described in concise but different forms of holistic methods such as Dinachrya, Rutucharya, Vyayam, Ayurvedic drugs & herbs, Upakrama of detoxification, Spiritual practices like Homa,Hvana & Yoga, Satvavajaya Chikitsa,Concept of Rasayana in the form of specific formulations & Acharya Rasayana- Sadavrutta, Yoga & Spiritual practices, Dhoopana therapy, useful drugs for formulations of Ayurvedic hand sanitizer and nasal spray for prevention & management of communicable diseases like COVID-19. All these remedies helps in developing immunity through their pharmacological & non pharmacological actions by inducing immuno modulation of essentially white blood cell, macrophages, natural killer cells.

Conclusions

Considering various preventive or curative measures of Ayurveda in the form of specific seasonal & dietic regime, proper Vyayam, rational & appropriate use Ayurvedic drugs, Shodhana Upakrama, Homa ,Havana & Yoga, Satvavajaya Chikitsa, Rasayana Chikitsa, Acharya Rasayana & Sadavrutta Palana, Yoga practices, Dhoopana therapy which are based on different basic principles of Ayurveda can be applied cumulatively for prevention & management of COVID-19. All these sources helps to prevent and control vicious cycle of infection by limiting their sources, preventing the routes of transmission, minimising portals of entry, and protecting susceptible patients by improving immunity. All above factors can be highly recommended for persons of active phase and who are in quarantine stage or those are in vulnerable group for COVID -19 However, further extensive research are needed to establish their authenticity, applicability in present era & to identify their limitations in various stages of such disease condition.
