government health bureauc-rats have often supported and pushed such shit. Many of these medicines and knowledge originally comes from ancient plant medicine. But one cannot patent wild plants (Well I guess Monsanto would love gene modify and patent even the trees) .
Find a plant medicine that work. Next claim the plant substance gives too big variation in the dose, so not should be used as medicine directly. Next synthesize it, now finally a standardized dose! Or even better change the molecule structure slightly, patent and synthesize. Do some cancer research on some rats for some months and if no cancer show up and ears dont fall off, well then claim no side effects and that everyone should take it all the time!
"Hippocrates, Galen, Pliny the Elder and others believed willow bark could ease aches and pains and reduce fevers. It has long been used in Europe and China for the attempted treatment of these conditions. This remedy is also mentioned in texts from ancient Egypt, Sumer, and Assyria. The first "clinical trial" was reported by Reverend Edward Stone, a vicar from Chipping Norton in Oxfordshire, England, in 1763 with a successful treatment of malarial fever with the willow bark. The bark is often macerated in ethanol to produce a tincture.
The active extract of the bark, called salicin, after the Latin name Salix, was isolated to its crystalline form in 1828 by Henri Leroux, a French pharmacist, and Raffaele Piria, an Italian chemist, who then succeeded in separating out the acid in its pure state. Salicylic acid, like aspirin, is a chemical derivative of salicin."
I think I cloned quite some Salix alba also in my younger days. Loads of different trees here in my garden...the deers eat a lot of them, 4 deers in my garden all summer.
dont eat too much willow bark, not good for u, but good to have at hand.
