The Building Blocks of Medical Astrology
Every object in our perceivable universe is composed of four building blocks called elements (fire, air, water and earth). Our bodies and minds are no exception. Disease arises when an imbalance in those four elements reaches a certain critical level. Too much fire indicates that our body is too hot and too dry, too much earth: too cold and too dry, and so on. That root imbalance will manifest through the weakest parts of our body/mind according to our constitution, history and environmental conditions; what we then see are the symptoms of the imbalance both physically and mentally.
The Four Elements
In Medical Astrology and humoral medicine, such as Eastern Medicine, those four elements are referred to as humors. They are:

YELLOW CHOLER
Element: Fire
Qualities: Hot and Dry

PHLEGM
Element: Water
Qualities: Cold and Moist

BLOOD
Element: Air
Qualities: Hot and Moist

BLACK CHOLER
Element: Earth
Qualities: Cold and Dry
The Diagnostic Method
An astrological horary chart is drawn in order to map out the conditions of a living organism and determine whether there is an imbalance present, its type and its degree. Recognizing these imbalances is the first step towards addressing them, through diet, lifestyle adjustments, and specific therapeutic interventions. This holistic approach aims to restore balance, acknowledging that our health is influenced by a complex interplay of factors.
