Just a heads up in the foray, here: homeopathic is not the same as herbal use. Homeopathic use could never create the result of an injured or severely compromised horse as cited. The molecules of the original substance--here wormwood--in a homeopathic dose are nil. It's essentially energy medicine that works very powerfully IF THE CORRECT REMEDY IS CHOSEN. If not, no harm; no foul. Herbal use, on the other hand, must be undertaken by someone expert as it, like allopathic medicine (that which is most familiar to us all) can do great harm.
