Skin cancer accounts for 45 to 80% of all equine (horse) cancers, the most common type being sarcoid tumours. Wikipedia
Wheatgrass extract can help remove these tumours and heal the tumour-damaged skin, by applying just a small amount over the affected area(s) just once a week - and persevering.
Case No. 1.
Cansema (black salve), effectively removed the sarcoid growth at the base of this horse's left ear but left an open wound that had not healed after three months. Application of wheatgrass extract healed the wound completely after 5 weeks daily application. (After many more years' experience working with wheatgrass extract for healing, I would now recommend once weekly application.)
Sarcoid wounds are invariably difficult to heal with Cansema because of damage done to the skin and underlying tissue which slows the healing process.
Note: "Dermawheat" preceded "Dr Wheatgrass" as a brand name. The products are identical.
Case No. 2.
The owner stated: "One of my horses had two sarcoids; one on her muzzle, the other on her hamstring. Dr Wheatgrass cream cleared them both up in a matter of weeks. I applied a small amount twice a day."
