Medical Astrology has its foundation in classical astrology and is a very specialised branch of astrology that deals with the health and wellbeing of the human body. The task of a medical astrologer is to analyse a person's birth chart and determine bodily strengths and weaknesses, susceptibility to illness and disease and even nutritional deficiencies. Medical Astrology is in no way a substitute for professional medical advice, however it can be used to gain a deeper understanding of general health related issues.
