In our current era of possibly over-engineered medical intervention, in which care is often substituted for cure, many people choose to explore traditional medicine as an adjunct to modern treatment. It is here that medical astrology holds importance: Medical astrology is not a form of medicine, but an add-on to traditional medicine. It provides a timing system, and an alternate method for evaluating the dynamics of humoural distribution in the body. In traditional medicine, the humours are the four primary fluids which mediate the health and physiology of the organism.

As a sophisticated system which developed over many centuries, medical astrology has various facets and cuts across many of the conventional astrological subdivisions:

  • Natal astrological applications include characterizing each person in terms of their elemental balance (thereby constructing a healthy lifestyle) and studying their disease susceptibilities by traditional organ type.
  • Horary applications include questions concerning the development of disease, and the study of decumbitures (astrological charts set for the onset of a disease or condition).
  • Electional applications include selecting times for surgery, the commencement of a treatment protocol, or the commencement of any other medical procedure.
  • Dynamic applications include studying the chart for future periods of stress that could indicate the development of chronic disease.
  • Psycho-spiritual applications include considering the ways that obstructions to the soul’s functioning and purpose back up into the body as disease.

The challenge, from a student’s standpoint, is that the breadth of disciplines necessary to do medical astrology well is close to daunting. Not only does medical astrology demand competence in natal, horary, and electional astrology, it also demands detailed understanding of traditional medical theory and its many philosophical implications. The STA Practitioners Level Medical Astrology Course offers a unique study opportunity for this particularly specialized subject. It fulfils the needs of astrologers who are seeking to appy its principles in practice, and also acts as a pre-requisite qualification for anyone wishing to advance to the STA Masters Level Medical Astrology Course, a top-level study course, which is designed to refine knowledge of this subject to a level of ultimate expertise.

This course introduces the natural philosophy which enlivened the historical development of Hippocratic and Galenic medicine. It explores the logic of traditional therapeutic methodologies to show how astrological systems were used for the analysis and timing of critical procedures. If you have ever used herbal preparations, you have employed components of this system, perhaps without realising. Knowledge of the framework largely depends on combinations of planetary rulerships and elements to offer deeper understanding of the use of herbs, extracts, flower essences, and essential oils.

The course also facilitates a more specialized, perceptive and confident judgement of medical horaries and decumbiture charts that were introduced in the STA Practitioners Level Horary Course. Delegates will be taught how to focus on identifying potential disease indicators in the nativity, as well as providing a system for designing wellness lifestyle decisions which positively address future patterns and natal imbalances.

This advanced level astrology course offers the STA Practitioners Level Medical Astrology Course in an online format. Lectures and workshops are delivered weekly over a period of 16 weeks through a combination of supplied course notes, modern media presentations, and online tutorials (there is an additional study break around the middle of the course). Lessons are structured as tutorials followed by assignments with thought-provoking questions, and consolidation of principles through practical application of demonstrated technique. Students study at their own pace and within their own time, but always with supplementary group discussion and access to the tutor.

A typical session will include: a live presentation, reading, an individual assignment (e.g., chart examples or workbook activities) and an assignment which encourages group interaction (e.g., forum discussion). Each week Lee will guide that week's course content, review student assignments, give personalized feedback and be available for questions and guidance.

Students receive their own set of personalised course notes which includes explanations of key principles, workbook-style activities, example medical astrology charts and answer sheets. This student workbook will also be cross-referenced with Lee Lehman's book, Traditional Medical Astrology, which acts as an accompanying text-book for the course.

Policies, Requirements and Recommendations

  • Students on this course do not need to have previous experience in medical astrology. However, this course specialises in advanced-level astrological training so it is necessary for participants to have a firm understanding of all basic astrological principles, and to have already studied certain principles that are generally taught as part of the study of horary astrology. For that reason, we recommend students to have previously undertaken the STA Practitioners Level Horary Course.
  • This is an English language delivery of the course so it essential that students have a fluent understanding of the English language.
  • Chart calculation is not taught as part of this syllabus, except for techniques specific to medical astrology (such as the calculation of temperaments, critical periods, etc). Participants are expected to be competently able to draw up and interpret astrological charts using basic natal techniques.
  • The course materials should be accessible on all modern computers. It is assumed that students have access to a printer, and it is necessary to have stable internet access, as all coursework is done online through the STA Course Portal. Students are required to download a free video conference program, Zoom, to enable interactive online sessions with the tutors and fellow students.
  • Students should regularly commit to the course and expect to spend between 4 to 8 hours per week to comfortably make it through all the course material and the associated exercises. The qualifying certificate is only issued to students who demonstrate their study and understanding of the material by successfully completing the set assignments.
  • Tuition materials are provided in a serialised form throughout the course, as PDF downloads. All materials used in the delivery of this course are strictly copyrighted and provided for personal study only – no element of them whatsoever can be reproduced or recirculated in any form. Video tutorials are not available for personal download and can only be accessed by logging in to the secure course portal. Graduates are allowed continued access to these videos and any other resources on the course portal for 12 months subsequent to the formal completion of the course, but tutorial support ceases two weeks after the formal completion of the course.
  • Places held by a deposit must be paid in full before the agreed deadline. If the full payment is not completed by the advertised deadline we reserve the right to offer the placement to someone else. In the unlikely event that the course is cancelled or postponed, STA will refund all course fees but will not be liable for any other additional costs personally incurred by participants.
  • If a student pays for the course and then changes his or her mind for any reason, a cancellation will be arranged and the refund of any payment is provided within 30 days of that payment. No refunds are allowed after this 30-day period or after the delivery of any formal course material has commenced. This is due to the fact that places on our courses are strictly limited and once a course is full we prevent further enrolments: therefore deposits paid to secure and hold a registration are non-refundable and non-transferable after the 30 day ‘cooling off’ period has expired.
