Collinsonia, also called stoneroot, is a North American plant. Herbal traditions used it to support digestion and soothe occasional hemorrhoid discomfort. No modern scientific studies confirm these uses.
Collinsonia is usually taken as a liquid extract or tincture. Doses vary widely because no standard dosing has been set through research.
Safety information is limited, so talk to a healthcare professional before using it, especially if you are pregnant, nursing, or taking medications.
