\section{Introduction}
 Corona Virus Disease (COVID-19) is a contagious disease caused by virus. It causes respiratory symptoms such as a dry cough, high fever, sore throat and, difficulty breathing in severe cases. It spreads by coughing, sneezing, personal contact, infected material, mass gatherings; one can avoid infection by regular hand wash, covering of mouth and by maintaining social distance. Cases were reported in Wohan city, Hubei province of china in the month of December 2019. On 7\ensuremath{^{th}} January 2020 they have confirmed COVID-19 as a causative virus. And on 30\ensuremath{^{th}} January 2020 WHO authorities declared that the outbreak constitutes a public health emergency of international concerns (PHEIC). 

No promising medicine is available for treatment and prevention till. Lot of studies is going on for treatment and prevention. In word near about 1,39,5136 cases are confirmed, 81580 confirmed deaths till 9\ensuremath{^{th}} of April 2020\ensuremath{^{}}\unskip~\citep{793928:19447245}. In India 5095 are active cases, 472 cured and 166 total death till 9\ensuremath{^{th}} April 2020 \unskip~\citep{793928:19447245}.\ensuremath{^{}} Lots of efforts are being taken by government for prevention and to stop spread of infections.

Drug has aphrodisiac property like Rasayan and Vajikaran properties mentioned in the ayurveda. Such drugs are always useful for building immunity and acts as an antioxidant. This property of plant may be useful for fighting viral infections and other complications. Also studies shows that maximum deaths are in vulnerable patients. In vulnerable patients we can use this plant for Rasayan and Vajikaran therapy. 

Local peoples are using this plant for diphtheria, head ache, demulcent and expectorant and diseases of lungs\unskip~\citep{793928:19447242}.\ensuremath{^{}} This property of this plant can be useful for infection of respiratory tracts and symptoms of viral infections. As decoction is used for gargles in throat infection hence it can be used for sore throat. Sore throat is one of symptoms in viral infection. 

It has very good pain relief activity\unskip~\citep{793928:19447242}. Peoples can use plant leaves with oil for pain relief. It is very beneficial for old peoples suffering from joint pains. It will save the side effects of pain killer medicines and save the money of general public, as income sources are restricted due to lock down. 

This plant is also used in malaria and fever\unskip~\citep{793928:19447242}.\ensuremath{^{}} Recent studies shows that anti malarial drugs are effective in the treatment of COVID-19. This plant may be used for fever in viral infections. 

As per Ayurvedic literature this plant is used in Prameha \unskip~\citep{793928:19447683,793928:18912173}. Diabetes is considered as one of the co morbidity in COVID-19. Hence this plant may be used to decrease co morbidity in viral infections. This plant has anti oxidant property\unskip~\citep{793928:19447687}. This property is very useful for boosting immunity to fight infections. 

Its Hepato protective property will be useful in the side effects of drugs on liver during the treatment of viral infections. Its wound healing property is proven on scientific basis and can be used in wounds to avoids untoward effects of antibiotics\unskip~\citep{793928:19447242}. \textit{Ehretia Laevis Roxb}.plant shows anti microbial activity on S. aureus, E.

\section{Results and Discussion}
This Ajan Vruksha plant also known as Khandu Chakka herbal plant, may be useful as antiviral drug and useful in symptom like fever and other associated infections in COVID-19 complications. 

This plant has major characteristic of Analgesic, anti arthritic and antinociceptive which is useful in severe body ache, inflammation in viral infection. It has chemical which has antioxidant \& anti-apoptotic property which is useful to built immunity in viral infection. 

Plant has many such chemicals which are useful in malignancy, obesity, blood sugar, cardio vascular diseases, blood pressure and lipids and muscle wasting to minimise the risk in viral infection, because maximum death in COVID-19 are associated with secondary complications. 

Plant has a property to fight infections of fungus and bacteria which may associate with viral infections. This herbal plant has chemicals which have very good effect on neural diseases like brain ischemia, and useful for promotion of neural crest cell survival, sedative, anticonvulsant, anti-Alzheimer, Antiseizure , antidepressant , stroke\unskip~\citep{793928:19447700}. 

Plant has thyroid uptake promotion property which will be useful for thyroid patients. Anticoagulant, antiplatelet property is useful in old age patients and bedridden patients, also this will reduce the risk in heart patients.  Beneficial chemicals to treat the peptic ulcer and cataract are available in this plant. This will help for prevention of diseases\unskip~\citep{793928:19447697}. 

Antiasthmatic property may be used for common cold one of the symptom in COVID-19. Antiosteoporotic and antiosteopenic properties are useful for old age patients and rural people as their movements are restricted due to lock down and limited resources.  

Chemicals present in this plant act as diuretic, has protective effect on human sperm, protection to testicular tissue, reproduction, useful for kidney and reproductive organs diseases\unskip~\citep{793928:19447240}. 

Plant chemical has a property of larvicidal which is useful in malaria. And useful in cosmetics and skin care product, atopic dermatitis, increase immunity, Anti fatigue activity.

Rutin from this plant is responsible for Neuroprotective activity, Retinoprotective, Protective effect on lung tissue hence this will be useful in COVID-19 pandemic. Also it has Cardioprotective ,  Hepatoprotective, Nephroprotective, Protective effect on blood vasculature, Wound healing property , Radio modulatory effects and help in prevention of splenocyte apoptosis. These properties can be used in associated conditions of the patient. 

A chemical from plant is useful in Asthma and can be used in bronchodilator in chest infection. It has antidepressive activity. As many people are in lock down from many days hence there may be chance for depression. To overcome depression this property may be used. 

To protect other organs in infection or for maintenance of proper health by its gastro \& hepato protective, antipancreatitic, anticholytic, anti diabetic \& hypolipidemic effects are very useful. It contains piperazine it may be used as Anti-helmintic. Deworming of population is very important to maintain proper health to fight infection. Phenylephrine is available in this plant; hence this plant may be used as a decongestant in flu like symptoms.
