Astrology and Medicine – the charts

There are three primary methods of medical charting in astrology. The first is the natal chart which is used to discern patterns and constitution. The second is the decumbiture which is the chart calculated for the moment a person develops a condition. The last is the medical horary, which is calculated at the moment the physician understands the inquiry. The horary was often conducted at the time the urine was inspected. Culpeper had very low regard for this method, emphasizing the Decumbiture as the appropriate method for medical practice.

One factor that drives chart selection is the availability of accurate data. It was uncommon for the average person to possess their birth data in premodern times. This fact predisposed the medical astrologer towards available data in the form of either the decumbiture or the medical horary.

In decumbiture – the 1st house is the patient, the 6th is the disease, the 7th is the physician, the 10th is the treatment. The placement of the moon can be compared with the natal chart if available.

In medical horary, the 1st house is the physician, 10th is the patient and the 7th is the condition. The moon is a vital consideration. Planets that it has close association with at the time of inquiry speak to the condition. Further, the moon may be checked at 10 and 40 degrees from the moment of inquiry to understand its status at that time.
