If you are feeding herbs for healing or calming purposes then it is most effective to feed the herbs on a daily basis throughout one full blood cycle, which is 3 months (12 weeks). The condition should be vastly improved over this time to the point where further supplementation should no longer be necessary.
Herbs as a rule should not be fed to pregnant animals, as many of them have uterine or hormonal stimulant properties. Before feeding a herb to a broodmare or foal, please consult with a vet or holistic animal practitioner to substantiate safety of a specific herb. The information provided by us on this site is intended solely for animals older than six months of age.
