Astrology of the Body and Health
Medical astrology correlates astrological symbolism with human physiology, anatomy, and health. Each zodiac sign governs a body region (Aries rules the head; Taurus the throat; Gemini the lungs and arms; continuing through Pisces and the feet). Each planet rules specific organs and physiological processes: the Sun rules the heart; the Moon rules the stomach and fluids; Saturn rules the bones and joints. The natal chart is read as a constitutional blueprint potential health strengths and vulnerabilities.

Using Medical Astrology Responsibly
Medical astrology should never replace professional medical diagnosis or treatment. Its value is constitutional understanding chronic tendencies, timing of health challenges (via transits and progressions), and the psychological roots of physical symptoms. A 6th house Saturn in Capricorn may point to a lifetime tendency toward skeletal or joint issues; this is a prompt for preventive care, not a diagnosis. Always work with qualified healthcare professionals; use astrology as a complementary lens for self-understanding and wellness planning.
