Re: Medication in horary
Just so you know, if you are seeking medications, there are Planets that rule them, and you want them to be in good condition when you do that. However, that applies only to herbal or homeopathic treatments. I do not know how to convert that to cover modern chemical based medicines.
Still, as far as how a medication will affect someone, you look to the Moon, her condition, and Planets in aspect to her. So the Moon in Air Signs would affect the digestive tract, and if the Moon were in good condition, and any aspect with Venus/Jupiter or a trine from Sun or Mercury it should work well.
If the medication was intended for something else, and Moon was in an Air Sign and impeded or in bad condition, then you might see side-effects in the digestive tract. The Air Signs also signify blood.
Water Signs signify bodily fluids (among things) so perhaps dry-mouth or cotton mouth is a side affect (common with many anti-depressants). Could also result in excessive urination or just the opposite (water retention).
Addressing his pupil, Satyacharya said, "The science of Astrology is a great secret. It should be guarded with care. This sacred science of Astrology should never be taught to bad people. Nor should it be revealed to too many people and very frequently. It should be taught only to a few chosen disciples who really deserve and have the necessary qualifications."
