Clinical skills

A deeply-rooted approach to assessing and treating clients with herbs, hydrosols and essential oils based on the Traditional Chinese Medicine (TCM) Diagnostic Patterns of Disharmony, Yin-Yang and the Five Elements, and techniques including tongue and face diagnosis. Look forward to many clinical observation hours in class to see this in practice.

This is combined with the compelling research evidence for the benefits of herbs and essential oils and their key chemical compounds — empowering practitioners with an integrated pharmaco-energetic understanding of how 200 different plant medicines exert their therapeutic actions.

Expert guidance

Our Diploma Course is unique in that it provides live learning experience every week (not pre-recorded self paced videos) with both Gabriel and AC as well as 1:1 mentorship. The purpose of this course is to give you the skills and knowledge required for forging - or further developing -  your Clinical Herbalism and Aromatherapy professional practice or your herbal product-making or retail business. 

AC and Gabriel are passionate about sharing their knowledge and expertise and, between them, have over 50 years of experience working with and teaching Herbalism and Aromatherapy.

Herb Craft

Our program features a deep-dive into sustainable Herb Craft and Medicine Making — encompassing the growing and preparation of herbs for extraction and distillation as tinctures, glycerites, and other extracts; liniments, salves, and ointments; and how to use essential oils and herbal hydrosols.

AC teaches how to craft herbal-infused oils; vinegars and oxymels; syrups, tinctures and fluid extracts; mushroom powders; liniments (topical herbal-infused rubbing alcohols); salves and creams; infusions, decoctions and tea blends, and more!
