Planets in Medical Astrology
Psychologically, the planets represent certain essential functions of the mind and personality. Physiologically, the planets represent essential bodily functions, and have affinities with certain organs and organ systems.
Classical Greek or Hellenistic Astrology had only seven planets: the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn. Together, these represent or symbolize all the basic, ordinary functions and drives of the body and mind.
Three of these planets are Yang or emissive in nature: the Sun, Mars and Jupiter.
Three of these planets are Yin or receptive in nature: the Moon, Venus and Saturn.
The seventh, or Mercury, is neutral or hermaphroditic, and can be either emissive or receptive, depending on its placement.
Starting in the 18th century, three more planets were discovered: Uranus, Neptune and Pluto. They also have their respective correspondences and significations in Medical Astrology.
In addition, there are also various important points in the natal horoscope that aren’t really planets but function as such in astrology’s symbolic language. The most important of these in Medical Astrology is the Ascendant or Rising Sign. Other important points include the angles and the lunar nodes.
Functional Classifications of the Planets
The planets can be classified into four different functional groupings, as follows:
- The Luminaries: the Sun and Moon. These “planets” provide most of the light in the heavens. Similarly, they represent the main power sources of the bodymind that drive all its functions.
- The Personal Planets: Mercury, Venus and Mars. These rapidly moving planets represent important factors that define basic characteristics of your personality: how you think (Mercury), how you love (Venus), and how you fight (Mars). In Medical Astrology, they flesh out and expand on the core functions of the Sun, Moon and Ascendant.
- The Social / Developmental Planets: Jupiter and Saturn. These slower moving planets aren’t so personal, and define how we relate to larger groups of people, and to society in general. Medically, they’re important regulators of the overall metabolism and govern the slower growth and developmental processes of the organism.
- The Outer Planets: Uranus, Neptune and Pluto. Whereas the seven classical planets are sufficient to represent all the basic, ordinary functions of the bodymind, the outer planets represent certain extraordinary functions or capabilities that could even be called paranormal.
