eli5: why are the long term effects of herbal medicines unknown?

528 viewsBiologyOther

for example, ashwagandha or valerian. whenever you search them up it states something akin to “safe to use for up to 6 weeks. long term effects are unknown”

people have been using these medicines for centuries… can’t they just conduct research?

We have more potent, synthetic alternatives to those plants.

Researching the long term effects of a drug costs money. It is considered worth it if there are benefits to distributing and using them, wether those benefits are financial or for the betterment of society.

So, although it would be nice to know what these effects are, there are currently better places to put that research money.
