Cat's Claw has been shown in laboratory research to have powerful effects on the process by which certain white blood cells engulf and destroy foreign particles (phagocytosis). In theory, Cat's Claw treats bacterial and viral infections as well as prevent or slow the progression of cancer.

Cat's Claw also boosts the immune system to fight infections, cancer, HIV infection, and allergies. It also alleviates gastrointestinal symptoms, such as those arising from ulcers, gastritis, and hemorrhoids. Wounds are also sped up in the healing process.
