Medical astrology (traditionally known as Iatromathematics) is an ancient medical system that associates various parts of the body, diseases, and drugs as under the influence of the sun, moon, and planets, along with the twelve astrological signs. Each of the astrological signs (along with the sun, moon, and planets) is associated with different parts of the human body. The underlying basis for medical astrology, astrology itself, is considered to be a pseudoscience or superstition as there is no scientific basis for its core beliefs.
Medical astrology posits the association of each sign of the zodiac with parts of the body, and was already mentioned by Marcus Manilius (1st century AD) in his epic poem (8000 verses) Astronomica. The signs of the zodiac were believed to preside over the parts of the body, covering the body from head (Aries) to toe (Pisces), as follows:
- Aries - head, face, brain, eyes
- Taurus - throat, neck, thyroid gland, vocal tract
- Gemini - arms, lungs, shoulders, hands, nervous system, brain
- Cancer - chest, breasts, stomach, alimentary canal
- Leo - heart, chest, spine, spinal column, upper back
- Virgo - digestive system, intestines, spleen, nervous system
- Libra - kidneys, skin, lumbar region, buttocks
- Scorpio - reproductive system, sexual organs, bowels, excretory system
- Sagittarius - hips, thighs, liver, sciatic nerve
- Capricorn - knees, joints, skeletal system
- Aquarius - ankles, calves, circulatory system
- Pisces - feet, toes, lymphatic system, adipose tissue
The western astrology planets are also associated with certain portions and functions within the body:
- Sun - heart, spine, and general vitality
- Moon - stomach, digestive system, female organs, lymphatic system
- Mercury - brain, central nervous system, thyroid gland, five senses, hands
- Venus - throat, kidneys, thymus gland, sense of touch, ovaries
- Mars - muscles, head, adrenal glands, senses of smell and taste
- Jupiter - liver, thighs, feet, growth, pituitary gland
- Saturn - skin, hair, teeth, bones, the body's defenses, spleen
- Uranus - parathyroid gland, neural activity, aura
- Neptune - pineal gland, psychic healing
- Pluto - pancreas, metabolism, elimination
After examining an individual's natal chart, a medical astrologer may give advice to the client about the areas of the body in which they are most likely to experience trouble. For instance, an individual with the Sun, Moon, Ascendant, or many planets in the sign of Aries is presumed to have more headaches than other people because of the association of Aries with the head. A person with Taurus strong in the natal chart is predicted to have many sore throats and problems with the voice because of the Taurean association with that particular part of the body.
