Yes. Some herbs like digitalis and such are quite powerful. But you have to measure your bodyweight and constitution versus quantity and knowledge which part of the plant to use.
Also the consistency of the active substances differs per plant. So think for the more potent plants, you need chemistry and knowledge of herbs/plants to use it safely and effectively. Less harmful things like lotus seed or dandelion are safe for general use and effective enough.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
