My garden is full of 'medicinal' and perfume plants, wild and cultivated that I prepare and use in varying forms - for personal use, only.
The tough thing these days about using the terminology 'medicinal' are the gov regs set in place to prevent scam type herbal supplement businesses and low or incomplete knowledge herbal practitioners.
Herbal medicine has a centuries long history, but imo without in-depth education it can be a dangerous pursuit.
Not trying to preach...but please proceed cautiously if you use plant medicine.
