The History of Medicinal Cannabis Hemp used to treat Horses Green Geo 29.12.2013 Medical marijuana Cannabis for dogs and cats is one thing. But medical marijuana for horses!? Yes, it’s true and it’s not a new concept in veterinary medicine. Cannabis has been used as a medical remedy for horses across the globe and the sands of time. From the ancient Greeks to modern-day farriers and horse owners, marijuana has been widely employed to successfully address a range of medical problems. There are numerous historical references to cannabis being used for sedation and as an adjunct to anaesthesia in equine medicine. Cannabis in Greek & Roman Cultures Greek writers reported the use of cannabis in treating horses–especially for dressing sores and wounds–and in treating humans. Here we find the dried leaves used against nosebleed and the seeds used against tapeworms, but the most frequently mentioned treatment involves steeping the green seeds in a liquid such as water or a variety of wine, then pressing out the liquid, which when warmed was instilled into the ear as a remedy for pains and inflammations associated with blockages. According to a collection of horse-remedies known as the “Berlin Hippiatrica”, the chopped leaves can be used to dress a wound: first some vinegar and pitch are brought to a full rolling boil, then wax, mustard, wheat- chaff, and roasted pine-resin are added, and the resulting mixture (presumably cooled) is applied liberally, then chopped cannabis leaves and grass trimmings are put on top before the wound is bound. Another collection, the “Cambridge Hippiatrica,” offers a recipe for the treatment of tapeworms which is identical to the one cited above from pseudo-Galen “On ready remedies” Overview of Potential Equine Therapeutic Applications for Cannabis • Used in a poultice (medicated bandage) to treat skin wounds • Fresh leaves were used to dress horses’ sores, dried ones against nosebleed. • A seed-based remedy used to treat tapeworms in horses • Used to treat colic and other gastrointestinal disorders A Remedy for Equine Colic? Until relatively recently, cannabis was found in a large number of veterinary medications designed to treat colic, spasmodic colon and other ailments in equine patients. The bottles of some of these drugs survive to provide us with evidence of the therapeutic benefits of this ubiquitous plant.
