Intro to Herbal Nervines
What are Nervines?
Nervines, simply put, are herbs known to relax, stimulate, or support the human nervous system.
How do they work?
Nervines are a very broad category, but in general they affect receptors on nerve cells, neurotransmitters, and other aspects of the nervous system and can be grouped by their action into
"anxiolytics, hypnotics, nerve stimulants, narcotics, nootropics, analgesics, and antidepressants"
(Dr. Sharol Tilgner; Herbal ABC's 2018)

Exploring the Wonderful World of Herbs
Want to take a deeper dive into the wonderful world of herbalism, but not sure where to begin?
Herbalism is a deeply complex, whole-body, multi-systems specialty and therefore the in-depth knowledge and expertise needed to practice adequately and safely should not be left up to Artificial Intelligence, which is known to hallucinate and make up information.
First Up:
-
Join a real-life in-person "Plant Walk" with an accredited Herbalist
-
Take an online or in-person class with Deep Roots Herb School (by Cameron Strouss, B.S., FH, RH (AHG), Aroma), or an accredited herbalist in your area.
-
Learn from the experts (Books, Herbal Databases, etc.), not AI.
You will get the most practical herbal instruction by doing hands-on activities with a real-life expert.
Knowledge as an empowering and joyous lifelong pursuit:
-
Use the herbal databases and reference books as a starter guide, and let your curiosity guide your search
-
Listen to expert interviews and podcasts (I'd recommend starting with Herb Reality, Herbs with Rosalee, and Herb Radio)
