@kekkerel @PraxisOfEvil @SapientPearwood Personal and second-hand experience (YMMV), but if you’re interested in herbal medicine, a few books that are very much worth having are:
- The Lost Book of Herbal Remedies (Nicole Apelian and Claude Davis)
- Encyclopedia of Herbal Medicine (Andrew Chevallier)
- The Modern Herbal Dispensatory (Thomas Easley and Steven Horne)
I also occasionally read Dr. Axe articles.
For growing your own, the best teacher is experimentation. Find some herbs you think are interesting, check what kinds of climates they grow best in, and if it matches your climate, buy some seeds and give it a try. It’s not an exact science, either…I’ve had some things grow very well where I am that the guidebooks said wouldn’t and vice versa.
