The Tincture Making 101 Mini Course and Mastering Herbal Formulations Course both teach about making herbal preparations, considering phytochemistry and solubility, and formulating herbal blends. TM101 of course focuses solely on tinctures, with lots of video tutorials, while MHF also shares guidance on making other herbal preparations as well. Both discuss phytochemistry and solubility in some depth, with MHF getting in deeper. TM101 includes a lesson on formulation including the ABCS Formulation method, while MHF includes a multi-lesson unit on formulation and discusses a step-by-step approach to formulation as well as the triangle method of formulation - and considerations for topical formulas as well.

If your focus is learning how to make tinctures using multiple methods and getting an introduction to building formulas, TM101 is a great fit. If you are focused on diving in deep into formulation, MHF is a great fit. They really would complement one another, as well!
