The WHO has approved phase 3 trials for some African herbal remedies for Covid. They are turning to science to see whether there are safe and effective traditional therapies to be adopted, it said.
It all sounds a bit "out there" and witch doctorish to those of us in the West, but herbal / plant based (modern) drugs have been with us for many years, some of them are based on thousands of year old remedies. Think along the lines of aspirin, quinine, morphine, penicillin and LSD and you can begin to understand the thinking behind the trials.
Many of them might / will not work, but that is also the case with some of the 140+ Western lab based vaccines we are testing.
