This is classical case of intellectual nonsense....
They are just taking advantage of the current situation...
At the most the so called drugs have multi vitamins and minerals... They are not immunoglobulins or antivirals...
I some how feel these kind of un-scientific claims should be banned by all goverments...I fact alternative medicines like homeopathy etcsetc also be removed from medical systems..
Allopathy went till dna/rna level and these traditional alternative medicines rely upon beliefs of people
