Traditional Medical Astrology
Traditional medical astrology is the branch of astrology that reads health, temperament, bodily regions, and treatment timing through signs, houses, planets, and cycles. It does not stop at symbolic description. In the older material, diagnosis, constitution, and treatment timing belong to the same world of practice.
Core frame
William Morris describes the constitutional side of medical astrology in explicitly humoral terms. He treats temperament as a fundamental part of the art and argues that constitutional analysis starts with the ascendant, nearby planets, and the ruler of the rising sign. He also emphasizes that the background conditions of day, month, and year contribute to the larger picture of the native's humoral balance. That gives this section its basic structure: medical astrology is not only about isolated symptoms, but about constitutional pattern. (Morris, Cycles in Medical Astrology, chapters on constitution and humors)
Body regions and houses
Medical astrology also maps bodily regions onto astrological structure. Morris gives one modern traditional account in which houses are correlated with specific areas of the body, while the ascendant remains a central indicator of the body as a whole. That is why this section includes both sign-based and house-based body mapping rather than treating them as unrelated systems. These pages belong together because practical medical astrology has historically worked through multiple layers of correspondence at once. (Morris, Cycles in Medical Astrology, astro-anatomy sections)
Why elections belong here
The electional material preserved by Dykes makes it clear that traditional medical astrology was never only diagnostic. The same corpus includes chapters on healing the sick, remedies pertaining to surgery, and bloodletting. Those chapters treat the Moon, the relevant houses, and the planet ruling the affected body part as practical factors in choosing when a procedure should begin. That is why Medical Elections belongs in this section just as much as Planetary Humors or Body Parts by Sign. (Dykes, Choices & Inceptions, Part III, chs. II.2.6-8)

How to use the section
The best way to read this section is to move from constitution to location to timing.
Start with the humors and temperament pages, because they explain the older medical logic behind heat, cold, moisture, and dryness. Then move into the body-part and house pages, which show where conditions are being located in the chart. Finish with the electional material, where the same framework becomes procedural and asks when treatment, intervention, or bodily change should be undertaken.
Scope and caution
Traditional medical astrology is historically important and structurally rich, but it is still part of a premodern medical worldview. These pages are most useful as study material for understanding the old astrological logic of health, temperament, and timing. They should not be read as a substitute for modern medical care.
