About this speaker
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 35 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 and massage therapists alike, who want to deepen their foundation as practitioners. 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, Tom Brown, Jr. and especially Stephen Buhner’s pioneering work on the heart as an organ of perception.
Tammi also offers online courses that integrate physiology and plant medicine with her love of teaching, such as her signature course Anatomy & Physiology for Herbalists. The other branch of her teaching is Cannabis. Teaching these two courses led to publishing two books; The first; The Wholistic Healing Guide to Cannabis and her second, The Beginner’s Guide to Growing Cannabis.
Heartstone Center for Earth Essentials was founded by Tammi Sweet and Kris Miller 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.
Woodland Essence's intention & practice is to offer high quality herbal products prepared by hand from organically grown & ethically wildcrafted plants. The challenges of tick-borne infections has fueled our search for plant medicine that can help people on their journey back to health & well-being.
