I do have my own personal favourite books but you have to bear in mind where you live (are you in the US?) and whether you are interested in only western herbal medicine or would you like to incorporate traditional chinese and ayurvedic medicine too. The two best books I can recommend that I find really useful are The Complete Herbal Tutor by Anne McIntyre and Practical Herbs by Henriette Kress. Good luck and above all, remember that you don’t need a school to learn these skills - there is so much information freely available on the internet and the plants themselves are the best teachers. Take your time, get to know them, experiment and enjoy the adventure!
The profession of herbalism was abolished in France in 1944, and only pharmacists and medical doctors are legally allowed to practice now (and this therefore creates a monopoly that goes against EU law.)
This petition asks the French Minister for Health to reinstate the profession. We still need more signatures, please help to support herbal medicine in France! Thank you!
