Homeopathy is widely practiced in Great Britain in the thoroughbred game. For several years before my retirement, I sold homeopathic remedies in the U.S. with varying degrees of success with many equine problems. Two of the most responsive were "nervousness" and "respiratory problems". A surprising number of buyers were veterinarians...
Some of you may be interested in which remedies and strengths to use for some common equine problems. You can download a simple guide which I wrote and offered when I was more active. Available for the next week. Good Luck!
(I do NOT sell these remedies any longer, suggest you use Google if you're interested)
