McDowells Herbal Treatments - White Willow

Known as the original source of salicin—the natural compound that later inspired the development of aspirin—willow bark remains a widely used herbal support for horses today.

In equine care, willow bark is often given to help manage inflammation and discomfort associated with conditions such as arthritis, rheumatism, or general aches and pains. Once ingested, the salicin in willow bark is converted by the body into salicylic acid, which works similarly to aspirin by reducing the production of certain prostaglandins—hormone-like compounds that trigger inflammation and pain in the joints and muscles. Multiple studies have shown willow bark’s natural anti-inflammatory properties, making it a gentle, plant-based option for supporting comfort and mobility in horses.
