Pain Pathways and the Correlating Herbs

Understand the pain pathway and A & P; interventions to help

  Enroll in Course

Many of our clients come in with both acute and chronic pain.

The best way to assist them in their healing path is to have a deeper understanding of the mechanism of pain, the reason for it physiologically and ways of relieving it when necessary.

This class will explore the pain pathway from the origin, all the way up to the recognition in the brain. Next the class will discuss the different types of pain; acute, chronic, nociceptive, inflammatory, dysfunctional and neuropathic, their etiology and mechanisms. Finally the class will explore the latest findings in pain research, the myriad of methods to interrupt the pain pathway, how these methods work and finally their indications and contraindications.


"“I love Tammi's way of bringing complicated subjects to life in an accessible and fun way. She never patronizes or talks down to us. She just invites us in through a kind of magical door." – Marlaine Darfler, Massage Therapist

Tammi Sweet

Tammi Sweet loves to teach. It’s her superpower. She has a magical ability to connect with almost anyone when teaching and help them understand complex material.

For over 30 years, Tammi has shared her gift of teaching at various colleges, massage schools and herbal schools throughout the country. Her background in physiology makes her an invaluable resource to developing herbalists, massage therapists and anyone wanting to care for their bodies alike, who want to deepen their foundational knowledge of the body.

In addition to her physiology expertise, Tammi is also a practitioner and teacher of herbal medicine. She is deeply influenced by her studies with accomplished herbalists, including Rosemary Gladstar, Pam Montgomery, Brooke Medicine Eagle,Tom Brown, Jr. and especially Stephen Buhner’s pioneering work on the heart as an organ of perception.

In 2007, Tammi set out to “combine all the things I love into one curriculum and teach whatever I wanted in ways that made sense--on my own terms.” So she and her partner Kris Miller launched the Heartstone Center for Earth Essentials.

At Heartstone, Tammi and Kris run two residential programs, an Herbal Apprenticeship and Journey of the Heart. They also offer online courses that integrate physiology and plant medicine with Tammi’s love of teaching, such as her signature course Anatomy & Physiology for Herbalists.

Tammi’s vision is for Heartstone to co-create a space with the land, where people can come "home," take refuge and find the sacred both on the land and within themselves and facilitate healing. When not teaching, Tammi loves to spend time alone and ‘recharge’ by exploring the land, writing, and hiking.
