Anticor, (“anti” meaning “before heart”) is a dangerous inflammation or swelling of the horse’s breast. The inflammation, which is located opposite the heart, is similar to the size and shape of an apple.

A veterinarian does the traditional treatment for Anticor as it involves the splitting of the skin where the tumor is located, which allows the matter contained to be removed. This also involves stopping the hemorrhage by using a hot iron. Inflammatory tumors are treated using oil of pompillion, a solution made of buds from black poplar, belladonna, lard, poppy and others. However, if the infected horse has formed abscess, a soft poultice is typically applied first before other treatments.

The only sign of anticor is the inflammation of the chest. It may appear as a hard tumor, develop slowly and becomes inflamed.

Anticor was believed to be caused by sanguine and bilious humour. However, modern medicine has proven that the condition is caused by the inflammation of the throat and the gullet.
