Please note that I am not writing it is not working. As there has not been a multitude of studies done ( done to an accepted scientific quality) we must be careful.
Plants and fungi ( plus many animalia) contain powerful pharmacological agents. New ones are discovered all the time.
The dangers in taking untested medications are many.
Contain toxins? Interact between each other with negative result?
Interact with pharmacological medication?
Effect on the foetuses? Transmits through the breast milk?
Many more aspects to be considered!
Just two wellknown examples.
Grapefruit interacts with several pharma medicines.
St Johns wort ( Hypericum perforatum) too.
Both interacting negatively.
We must be careful of damaging ourself in our quest for health!
One negative with funghi not many foragers think about is that they can concentrate stuff like heavy metals, including radioactive isotopes.
One aspect with herbal medicines that I find very appealing is that most traditional herbals are very mild.
Yes, you can take a prescription sleeping pill. You can also take an infusion of herbs, and have ( basically) the same effect, without the negatives.
