Your nervous system is your antenna to the world - taking in and filtering all the information and experience you encounter in a day.

This highly sensitive system is easily disturbed - both by physical problems like neuropathy, but also by psychological troubles like uncompensated stress and emotional turmoil.

Indeed the whole field of psychoneuroimmunology is devoted to understanding the complex interplay of factors and feedback loops that makes it insensible to talk about nerve states and emotions as separate phenomena. We'll bring this heady theory down to earth and give you simple, practical tools to keep your nerves nourished and your emotions on an even keel with the help of some of our gentlest, yet most powerful, herbal allies.

The course includes 15+ hours of video instruction, as well as PDF handouts, quizzes and homework assignments, and integrated discussions where you can talk directly with Ryn and Katja.

This course begins in Spring 2020.

Supplementary content will be added in the weeks leading up to the course's start date. Video lessons will be released beginning on the start date.
