Summary of Medical Uses and Benefits for Equine and Canine Health: Milk Thistle Leaf is a gentle, supportive herb traditionally used to nourish and protect the liver, with a mild diuretic action that can also support the urinary system. Its key benefits include:

• Liver Support: Contains antioxidant compounds that help to protect liver cells from oxidative stress and support normal liver function.
• Supports Natural Detoxification: May help the liver process and eliminate waste products more efficiently, which is beneficial for animals on long-term medication.
• Gentle Diuretic Action: The leaf, in particular, has a mild diuretic effect that can help support the body's natural elimination of excess fluid.
• Urinary Tract Support: Its soothing and cleansing properties may help to maintain a healthy urinary tract and support normal kidney function.
• Digestive Comfort: Can have a mild bitter action that supports healthy digestion and bile flow, promoting overall gastrointestinal wellbeing.

Precautions:

• Avoid use in animals with a known allergy to plants in the Asteraceae family (e.g., daisies, chamomile, ragweed).
• As it may influence liver enzyme pathways, it can theoretically interact with medications processed by the liver; veterinary advice is essential for animals on prescription drugs.
• Its diuretic effect means it should be used with caution in animals with kidney disease or those on diuretic medications.
• May cause mild digestive upset, such as loose stools, in sensitive individuals when first introduced.
• Do not use in pregnant or lactating animals without veterinary supervision.
• A veterinary diagnosis is required for any animal showing signs of liver disease before using this supplement.
