Reddit mentions of Grow Your Own Drugs

you might find value in Rosemary Gladstar's books on medicinal herbs. There are a few that might be of interest to you. medicinal herbs for beginners, 175 herbal recipes for vibrant health, herbs for stress and anxiety, and family herbal are a few good ones to look into.

In the related listings I found several other great titles with good reviews on them. Among them, there was the herbal apothecary, the complete medicinal herbal, and the herbal medicine maker's handbook

I would also suggest James Wong, an ethnobotanist. He has a series that was on the bbc about using plants to make medicinal items. It was on youtube for a bit but is no longer there in its entirety. He does have a book on the series, though-
grow your own drugs. A sequel with more recipes can be found here- a year with james wong.

I also find that many sustainable living, foraging, and related sites tend to have good recipes you can sort through. here are a few of the ones i have saved.

lastly, a basic google search for "herbal remedies" brought me a few websites that look promising.

mother earth news- herbs for ailments and wounds

botanical.com has a few resources for recipe and information about plants, but it is more limited than i would like.

the family herbalist looks very promising.

there are probably a ton more out there, but i hope that some of these or the terms they use can help you find what you are looking for.
