Veterinary Herbal Medicine Overview

Veterinary herbal (or botanical) medicine is the practice of using plant products to treat diseases in animals . It’s a practice with ancient roots, dating back thousands of years and forming the origin for many modern pharmaceuticals . Today, about 75% of the world’s population still relies on herbal medicine for basic healthcare, and its use is growing in veterinary medicine, especially for chronic conditions like arthritis, skin issues, and anxiety

What is Holistic Veterinary Medicine?

Holistic medicine is a broader philosophy of care. As defined by the American Holistic Veterinary Medical Association (AHVMA), it is a form of healing that considers the whole patient—body, mind, and spirit—in its approach to achieving optimum health and treating the root causes of disease .

It’s an Approach, Not Just a Modality: A veterinarian practices holistically by considering all aspects of a patient’s life and health, regardless of the specific tools they use .
Integration of Therapies: After a thorough exam, a holistic veterinarian will choose the best combination of conventional therapies (like drugs or surgery) and complementary ones. These can include acupuncture, chiropractic, nutritional therapy, flower essences, physical rehabilitation, and, of course, herbal medicine

Always consult a licensed veterinarian with training in herbal medicine before giving any supplement to your pet. Herbal therapy should support, not replace, conventional veterinary care.
