They have dispelled using Hydrochloroquine based primarily on the severe side effects. There are, as yet, no approved drugs for treating COVID-19. We all know this. The FDA is an administrative body for approving drugs and medications not for researching potential treatments.

You stated: "(Also, we treat Quinine and Quinine-like drugs like Hydroxychloroquine the same class of drug (same family). i.e. we health professional don't give a dam whether it's botantical or synthetic. Ask your doctor or pharmacist if you are confused about the two."

So what you are saying is that you don't care about patient side effects? That's concerning.
