COVID 19 is spreading rapidly. Again. As the “third wave”. There are no dearth of concoctions that claim to “boost immunity”. What should you do ? Should you try them ? They seem to be “harmless” at worst and may be of some use? These are the thoughts among many these days.
My take :
Fact 1 : There is NO scientifically valid research on them
Fact 2 : I practice scientifically researched medicine
Fact 3 : I will “First do no harm”
Therefore I will recommend sticking to the basic prevention methods and recommend seeking early medical attention if sick.
