When I had COVID, I didn't realize at first that it was what I had, until I partially lost my sense of taste, and then it went to my chest, and my chest burned. Mainly in the upper half. None of the other natural remedies I usually take for viruses really did anything for me for reducing or eliminating symptoms, but when I tried resveratrol, it stopped my chest from burning. I took one capsule every day. I should have read the bottle because it said the dose was 2 capsules, which would have been 500 mg, but one capsule (250 mg) at least gave me relief from the burning. Eventually it cleared up. I took the resveratrol once a day for about 10 days, and the virus never went deeper into my chest. I have since done some reading on it, and in addition to being anti-inflammatory (the reason I chose to take it to begin with), it also apparently helps reduce viral replication. So, if I ever have to do this again, I would take the full 2 capsule dose and hopefully would knock it out faster.
