@Tai Chi,
rapid reactions to prophylaxis using Ivermectin (a well known veterinary antihelminth) is showing promising by lessening symptoms of covid in moderate to severe cases.
Studies being done are like th early mask studies, (non randomized, small sampling and only post infection). But data shows that it Could be some hopeful news for the population of India.
We use "Ivomec" as an anti worming agent for horses and non meat cattle (breeding stock). The tim required to take the animls off Ivermwctin so they can be sent to market is too long to hang on. For meat animls we use fullers earth and chrysnthemum and topical sprays.
Since we have cut down on cannibalism on earth, ivermectin can be used eeither as a drench or a time release caplet
