Advanced Herbal Formulae is a practitioner-level course in the art and discipline of composing herbal medicines as true formulae—coherent, intentional works designed to meet a defined therapeutic aim with precision. Moving beyond single-herb thinking, we study how plants behave in relationship: how to build a formula’s architecture, how to balance force with gentleness, and how to refine a prescription until it is both effective and elegant. Using the spagyric method of separation, purification and cohobation, you will learn various ways these processes can be utilized to create the classic formulations of herbal spagyric alchemy - the tincture, the essence, the elixir, the primum ens, the magistery and the summit of the whole work, the herbal stone. This program is for serious students who wish to deepen their craft and develop confidence in designing complex blends for real-world conditions. By the end, you will be able to construct advanced formulas with clarity, justify each formula's role, and revise your work through disciplined reasoning rather than guesswork—bringing your herbal practice into a more exacting, professional, and reliable form. This course is a mixture of a video lecture, practical video demonstrations, written content and a final assessment for completion.
