Antiviral herbal medicine, Active Zinc from Yasad Bhasma, Zinc Ionophore, RNA dependent RNA polymerase (RdRp) inhibitor.


In the present pandemic corona (Covid 19) situation as there is no specific drug recommended, many individual drugs & combination of drugs have been tried and tested. But in the war against Corona, a ray of hope in the global medical treatment is Zinc Ionophore with Zinc as there are quite a good number of doctors tried and still trying with a positive feedback.

HCQ role in Corona viral treatment is as a Zinc IONOPHORE.  Whereas Zinc as a mineral can’t directly enter in the cell, hence HCQ (as Zinc Ionophore) carries the Zinc ion in to the cell. REMDESIVIR helps to stop viral multiplication. Zinc is a strong RNA dependent RNA polymerase (RdRp) inhibitor which suppress viral RNA multiplication.

But HCQ has its own limitations in its usage because of the side effects like QT prolongation based cardiac toxicity, Nausea, vomiting, blurred vision or other vision change, Chest discomfort, pain, or tightness. Decreased urination. Defective color vision. Difficulty in breathing.

QUERZIN is an Ideal Natural alternative to REMDESIVIR but with the same mode of action as Zinc  ionophore. Active Zinc from YASAD BHASMA and selected herbs like Camella sinensis  extracts, Vitis vinefera extract provide antiviral property as well as boost our immune system very effectively which help to build immunity and contribute to herd immunity.

Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
People of all ages can be infected by the new coronavirus (2019-nCoV). Older people, and people with pre-existing medical conditions (such as asthma, diabetes, and heart disease) appear to be more vulnerable to becoming severely ill with the virus.
The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. QUERZIN also prevents pandemic virus spread in this present situation by improving herd immunity of our society.

    In the times COVID19, was looking for something which can counter virus effect, without having side effect or basically ayurvedic medicines.
    One of my friend suggested me this with couple of scientific evidences and their effectiveness of ingredients on virus effect on body. Was very much convinced after seeing all the videos and working of coronavirus and how it impact our body.
    Now coming to point where how to prove its effectiveness.. well till now i have remained safe and sound?. despite traveling for work, for grocery and veggies and all.
    I have suggested to many friend’s and family members and they remain safe and sound till now, who are using this medicine.
    Will suggest everyone to have it have on safety grounds and to protect yourself and your loved ones.. ??
    Safety is better than cure.
