Medical astrology is a branch of astrology that explores the relationship between the signs, planets, and houses in the birth chart and various physical and mental health conditions. It is based on the belief that the positions of the planets and other celestial bodies at the time of a person's birth can influence their physical and emotional health.
Astrologers who practice medical astrology will typically examine the individual's birth chart to identify potential health issues and to gain insight into the underlying causes of those issues. For example, the placement of the Moon in the birth chart is associated with the body's fluids and the digestive system, while the placement of Mars is associated with the muscular system and inflammation.
Some astrologers also use the concept of medical horary astrology, which involves casting a chart for the moment that a person first experiences symptoms of a health condition. This chart can provide insight into the underlying causes of the condition and may also suggest potential remedies or treatments.
