\begin{abstract}
Outbreak of ``Severe acute respiratory syndrome Coronavirus 2 (SARSCoV-2)'' infection took place in ``Wuhan, Hubei Province, China'' in December 2019, which spread across all over the Globe. WHO officially termed the disease caused by the new Coronavirus as ``Coronavirus Disease 2019 (COVID-19)'' on 12 February 2020. Being viral disease, at present no specific treatment or vaccines approved for COVID-19. Social distancing and practicing healthy lifestyle to boost immunity are the best possible options to deal with it. Though there is progress in Medical science regarding immunization and development of medicine, there is lack of vaccines for prevention of many viruses and effective antiviral medicines. India's Ministry of traditional medicine or AYUSH (Ayurveda, Unani, Siddha, Homeopathy) issued ``Advisory'' advocating preventive measures against the viral infection on 29 January 2020. There is severe criticism to ``Advisory of AYUSH Ministry'' from Indian Medical experts across the Nation for making such declaration in this global health crisis. The traditional healthcare system of the Nation offers supporting lifestyle for immunity enhancement which aids in keeping away from different kinds of infectious ailments. In recently occurred Corona epidemic it has been noted that it mainly affects the Respiratory system. AYUSH Ministry issued ``The Advisory'' to enhance defensive mechanism of the body for prevention of disease and not declared it as a curative measure for the Corona virus disease. This review focuses on the efficacy of the measures recommended by AYUSH Ministry on the basis of literature and researches available on them.

\section{Introduction}
The 2019{\textendash}20 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019, caused by ``severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)''. It was reported in ``Wuhan, Hubei province, China'' in December 2019. In subsequent weeks, disease extends and spreads across China and other countries. On 12\ensuremath{^{th}} February, 2020, ``Coronavirus Disease 2019 (COVID-19)'' is the term given by World Health Organization to the disease caused by new Coronavirus (9). WHO declared ``COVID-19'' outbreak  as pandemic on March 11 \unskip~\citep{831168:19821479}. 

Corona virus disease (COVID-19) is a zoonotic disease that is it pass from animal to humans, by intimate contact with infected animal and later it can be transmitted from one individual to another through droplets infection while coughing or sneezing or by touching infected surface. Fever, dry cough, tiredness, running nose, difficulty in breathing, bodyache, sore throat, vomiting and diarrhea are the main symptoms. Provisionally it can be diagnosed by clinical symptoms. Confirmatory tests are ``Reverse transcription polymerase chain reaction (rRT-PCR) of infected secretions'' or ``CT imaging of chest'' \unskip~\citep{831168:19821482}. 

Being viral disease, at present there is no treatment available for Corona infection but at this time medicines and vaccines for fighting against infection are under trial. Management strategies are symptomatic and supportive to maintain vitals, oxygen saturation, blood pressure and treatment of complications like secondary infection or organ failure (As per guidelines of WHO \& ICMR).  Good balanced diet and good healthy lifestyle by practicing yoga and meditation help to boost immunity. Preventive measures are of supreme importance like hand hygiene, respiratory hygiene, environmental cleaning and social distancing to prevent bacteria and viruses from spreading.

With the world gripped by the contagion of the novel Coronavirus strain from China, India's Ministry of traditional medicine or AYUSH (Ayurveda, Unani, Siddha, Homeopathy) issued an ``Advisory '' advocating preventive measures of Ayurveda against the viral infection on 29 January 2020 \unskip~\citep{831168:19821500}. There is severe criticism to ``Advisory of Ministry of AYUSH'' from medical experts of Indian Medical Association and Healthcare experts across the country for stating such statement at the time of global health crisis as there is no evidence. 

AYUSH system of healthcare supports traditional health practices. The traditional Healthcare system of the Nation offers supporting lifestyle for immunity enhancement which aids in keeping away from different kinds of infectious ailments. In recently occurred Corona epidemic it has been noted that it mainly affects the Respiratory system. AYUSH Ministry issued ``The Advisory'' to increase defensive mechanism of the body for prevention of disease and not declared it as a curative measure for the Corona virus disease. This review mainly focuses on the efficacy of the measures recommended by AYUSH Ministry on the basis of literature and researches available on them. 
    
\section{Materials and Methods}
Relevant literature, internet information and available research articles from Pubmed, Google scholar were searched, analyzed and summarized. 

The Advisory given by ``AYUSH health Ministry'' includes the immunity boosting measures for self care during ``COVID-19 epidemic''. Enhancing the body's natural defense mechanism plays an important role in maintaining optimum health. As there is no medicine available for COVID-19 till date, it will be good to take preventive measures which boost our immunity in these times. Measures shall be taken to strengthen the immune system through a balanced diet and healthy lifestyle practices.

Ayurveda emphasized on prevention of disease than cure. Ayurveda's extensive knowledge base on preventive care derives from the concepts of ``Dinacharya (Daily regimes)'' and ``Ritucharya (Seasonal regimes)'' to maintain healthy life. 

Ministry of AYUSH recommends certain guidelines for ``self care'' including health measures for prevention by enhancing immunity specially for strengthening respiratory health.

\section{Results and Discussion}
In Ayurveda epidemic diseases are described under the name of ``\textit{Janapadodhwnsa} \textit{vyadhi}''. According to Ayurveda, all types of bacterial, viral and epidemic diseases can be correlated with \textit{Sannipatik Jwar} (Fever caused by all the three \textit{Doshas}). Similarly as per symptoms of COVID-19, it is clear that it mainly affects upper respiratory tract. Hence the above mentioned guidelines in Table~\ref{tw-4854798374b3} are mainly based on Ayurveda principles which have action on respiratory and immune system. These measures help in balancing \textit{Tridoshas} and have ability to improve and strengthen the respiratory functions. 

Under general measures it is advised to practice healthy habits for maintaining personal hygiene by frequent hand washing with sanitizer or soap and water for 20 seconds. Then it is advice not to touch frequently with unwashed hands to the eyes, nose, and mouth, avoid visiting to individuals having symptoms by adopting social distancing and staying at home, cover the mouth while coughing or sneezing and wash the hands following coughing or sneezing. Frequently handled objects and surfaces should be clean with disinfectant. Mask should be used to cover nose and mouth while going outside. If symptoms of Corona disease observed then contact to nearest hospital immediately. All these measures are helpful in preventing spread of infection of CORONA-19. These all measures are mentioned in Sushruta Samhita while describing causes of \textit{Kustha } and termed it as ``\textit{Aupasargikaroga''} due to their nature of spreading from diseased person to healthy one through repeated contact. 

In Ayurveda for prevention, as stated in point no 1 of Table~\ref{tw-4854798374b3}, personal hygiene and good healthy practices are mentioned through concept of ``Daily regimen and Seasonal regimen''. ``Daily regimen'' described by Ayurveda is an ideal daily routine activity as per the nature's cycle for maintenance of good hygiene and health. It helps in maintaining equilibrium of \textit{Doshas} (biological energies of the body) and the \textit{Agni} (digestion fire) in proper state. It has also beneficial effects on physiological functioning of the body and mind. If one follows these practices properly, it will help in strengthening immunity and purification of the body by removal of wastes. 

 A ``Seasonal regime'' is the routine activity according to particular season described by Ayurveda. It helps to preserve good health as per the change of season. The main purpose of Seasonal regimen is to prevent disorders caused due to seasonal derangement of \textit{Doshas}. According to season, unique diet, behavioral activities and specific procedures are described in Ayurveda, to stay healthy. These help in maintaining equilibrium of \textit{Doshas} in the body and keep body and mind healthy \unskip~\citep{831168:19821491}.

According to Advisory of AYUSH Ministry against COVID-19 for ``self care'' stated in point no 2 of Table~\ref{tw-4854798374b3}, it is advised to drink hot water \unskip~\citet{831168:19821485}, by simply boiling it or reducing its quantity to 1/8th part or \ensuremath{\frac12}  part. \textit{Ushnodaka} increases digestive power, alleviates \textit{Kaphavata} and \textit{Pittadosha}. It is useful in fever, thirst and it also opens the obstructed channels. It is desirable in Respiratory disorders like cough, cold, asthma and fever. \textit{Ushnodaka} makes liquefaction of the dried and solidified phlegm by melting action and enables it to move. It helps in relieving obstruction of breathing by its bronchodilatory and expectorant action \unskip~\citep{831168:19821485}. \textit{``Shadang Paniya} is the aqueous decoction of a polyherbal preparation containing equal amount of six herbs namely ``\textit{Musta } (\textit{Cyperus rotundus }Linn\textit{.})\textit{, Parpat (Fumaria officinalis }Linn\textit{.)}\textit{, Usheer(Vetiveria zizanioides }Linn\textit{)}\textit{, Chandan (\textit{Santalum album}. }L\textit{.), }\textit{Udeechya ( Pavonia odorata }Willd\textit{)} \textit{ \& Nagar (\textit{Zingiber officinale}}Roxb\textit{.)} \textit{''} processed in water (10 gm powder boiled in 1 litre water, until it reduces to half)". It is used in initial stages of fever and thirst. It reduces excessive thirst, burning sensation, restlessness and distaste. It helps in increasing appetite. It alleviates aggravated \textit{Pitta }and\textit{ Kapha Dosha}. It reduces \textit{Ama} (toxic undigested food particles) and \textit{Amavisha} (toxins) from the body thus causing detoxification. Research paper presented by (March 2015) in National Conference on ``Novel tools and treatment approaches in health care system (ISSN:0975-8232)'' proved in vitro antibacterial activity of\textit{``Shadang Paniya''}. 

Yoga, Pranayama \& Meditation mentioned in point no 3 of Table~\ref{tw-4854798374b3}, are important to improve respiratory health and immunity, thus are involved in the prevention and healing from COVID-19. Practice of Aasana, Dhyana and Praanayama is the best way for mitigating the isolation anxiety during lockdown period and can practice at home in isolation.  Yoga provides good physical health, reduces mental stress, and improves all physiological functions of the body. Yoga, Asanas, Pranayama and Meditation are very beneficial and easy to perform at all ages and conditions. Many Research studies proved that Yoga has excellent effect on the number of red and white blood cells. In one research study they found significant increase in the level of neutrophils and significant decrease in level of platelets after three weeks of Yoga practice. Increased Lymphocytes after practicing Yoga proved that it improves immunity. They found significant increase in hemoglobin and antioxidant superoxide dismutase (SOD) level with a significant fall in leukocytes in the yoga group as compared to the control group \unskip~\citep{831168:19821488}. 

Spices like Haldi (Turmeric), Jeera (Cumin), Dhaniya (Coriander) and Lahsun (Garlic) possess appetite stimulating, digestive, and antimicrobial property which help in improving general health which are advised to follow in prevention as stated in point no 4 of Table~\ref{tw-4854798374b3}. Haridra (\textit{Curcuma longa} Linn.) has \textit{Tridosha} alleviating, bronchodilator, antipyretic, analgesic and antiinflammtory properties.
