In general, it should be noted that you need to do the previously mentioned test to determine whether Ivermectin is effective or not. In fact, one needs to increase the statistical population to prove that this drug doesn't have placebo properties. An experiment should be created where there are two groups, and the first group should receive the same drug, and it should be said that it is a drug and doesn't have many therapeutic properties. The second group should receive the same drug and patients should be informed that this drug has therapeutic properties. If this drug (Ivermectin) is a useful drug for coronavirus, it should be useful for both, otherwise it's just a placebo. But the interesting thing is that Ivermectin originated in the soil in the first place. Professor Satoshi Omura isolated an unusual Streptomyces bacterium in soil with William Campbell in 1975 and discovered that the bacterial culture could cure mice infected with the roundworm Heligmosomoides polygyrus. Campbell isolated the active ingredients from bacterial culture and named them "avermectins" (Crump and Omura, 2011). ---------- [More Information ][1] [1]: https://www.growkudos.com/publications/10.22541%252Fau.167407917.79134712%252Fv1/reader
