Medical Astrology is no longer a specialty that only a few astrologers can learn to use, as was the case for the last century.  Presented here is a step-by-step approach in teaching the logic of this field, which traditionally was part of every natal astrologer's work. Included are natal. horary, and electional methods, as well as an extensive history of medical astrology and its uses.  Dr. Lehman offers the traditional astrological methods for this system, also emphasizing that medical astrology was always an adjunct to medicine, not a complete system by itself.
