Astrology for Herbalists: core curriculum

Level 1 - apprentice. For those who haven't studied traditional astrology before. Three modules introduce key traditional astrological concepts and historical figures, how to calculate charts by hand, and the use of decumbiture (illness), consultation, and birth charts in medical astrology to guide prognosis, diagnosis and treatment.


Level 2 - intermediate. Suitable for students with a good grounding in traditional medical astrology, three modules provide a deeper dive into the technicalities of traditional medical astrology, incorporating additional prognostic tools such as crisis charts, answering medical questions with astrology (horary), and using the birth chart to calculate temperament and analyse congenital, inherited or "constitutional" health issues.


Level 3 - practitioner. Suitable for herbalist practitioners of medical astrology or those who have completed the preceding six modules! Three modules covering various topics such as controversial "length of life" techninques and their ethics and application, use of primary and secondary directions, profections and solar returns in the birth chart, medical elections, analysis of global health concerns with mundane astrology, and more!

Hi, I’m Marcos!


I began practising as a medical herbalist in 2004, initially specializing in complementary care for people living with HIV, working from Neal’s Yard Remedies’ Therapy Rooms and Tony's Holistic Centre in London. I worked as a dispenser in Middlesex University’s training clinic for their Western Herbal Medicine BSc in 2009-2010, and later as a clinical supervisor for the Western Herbal medicine BSc and MSc courses at Middlesex from 2013-2018, and for Westminster University in 2021-2022, and Heartwood online in 2020-2023.

I'm also a medical and horary astrologer, and a lifelong student of renaissance and classical astrology. I'm an affiliate tutor for Kepler College in the U.S.A., the UK Qualified Horary Practitioner (QHP) school, and a faculty member of the Academy of Astrology UK. My first book, The Secret Life of Chocolate (thesecretlifeofchocolate.com), was released in 2020, and the forthcoming paperback "herbalist edit" of this book - Pharmakakawa: Theobroma cacao in medicine and ceremony, is due for release in 2024.
