Bloodroot - Sanguinaria canadensis
Bloodroot, Sanguinaria canadensis, is a flowering herbaceous plant native to the Northeastern United States. It tends to grow in old-growth areas with moist, but well-drained soil and part shade. It is protected in some states so take care if you harvest.
The red root or rhizome can be used to make a dye. Indigenous Americans used it as an emetic, for gastrointestinal issues, for tuberculosis, skin wounds and rashes.
Studies have shown that the sanguinaria component does display activity against cancer cells.1 However, it does not distinguish between normal cells and cancer cells so it can cause tissue destruction and necrosis. 2 Caution is warranted.
Bloodroot, with its antibacterial and antiviral properties, has been used in dentistry to treat periodontal disease. 3 My household finds it effective for stubborn facial blemishes and bleeding gums.
