Bloodroot is spring perennial native to the East Coast of North America. Bloodroot is the only species in the genus Sanguinaria, which is included in the poppy family. Bloodroot is most closely related to Eomecon of eastern Asia. Bloodroot plants are variable in leaf and flower shape and have in the past been separated out as different subspecies due to these variable shapes. Currently most taxonomic treatments include these different forms in one highly variable species. The sap from the bloodroot plant is a vibrant orange red colour and is poisonous. The latin name 'sanguinaria' is derived from the latin word 'sanguinarious' which means to bleed. The species name 'Canadensis' translates to of Canada in reference to the abundance of the plant in Canada.

Bloodroot is generally used as a spring ornamental plant. Commercial uses of sanguinarine and bloodroot extract include dental hygiene products.

Within the realm of rational and holistic medicine, Bloodroot was a traditional remedy of native North Americans who used it to treat fevers and rheumatism, to induce vomiting and as an element in divination. In modern herbal use it is chiefly employed as an expectorant, promoting coughing and the clearing of mucus from the respiratory tract. The root is used locally as an anesthetic, or sedative tonic. Bloodroot is taken internally in the treatment of bronchial, respiratory tract and throat infections, and poor peripheral circulation. Externally, the root is used in the treatment of skin diseases, warts, nasal polyps, benign skin tumours, sore throats and chilblains. An infusion of the root or the sap of the fresh root is used. The root can be harvested in the autumn, dried and stored for later use. It should not be allowed to become damp since it will then deteriorate. Sanguinarine, which is obtained from the root, is used as a dental plaque inhibitor. The root is used to make a homeopathic remedy that is used to treat migraine. The US FDA has approved the inclusion of one of the active constituents, sanguinarine, in toothpaste as an antibacterial and anti plaque agent. A red dye is obtained from the sap of the root and was used as a face paint by North American natives. The crushed root has also been applied to the body as an insect repellent.

Bloodroot is considered to be toxic and should not be used as a food source.

Bloodroot can grow in light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acidic soils. Bloodroot can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Notes:  

Bloodroot grows from 5cm to 15cm tall with one large basal palmately scalloped leaf up to 12cm across, with five to nine lobes. The leaves and flowers sprout from a reddish rhizome with bright orange sap that grows at or slightly below the soil surface. The rhizomes grow longer each year, and branch to form colonies. Plants start to bloom before the foliage unfolds in early spring. After blooming the leaves expand to their full size and go summer dormant in mid to late summer. The flowers bloom from March to May depending on the region and weather. They have 8 to 12 delicate white petals and yellow stamens, and two sepals below the petals, which fall off after the flowers open. The flower stems are clasped by the leaves. The flowers are pollinated by small bees and flies. Seeds develop in green pods which are 40mm to 60mm long, and ripen before the foliage goes dormant. The seeds are round and black to orange-red when ripe, and have white elaiosomes, which are eaten by ants.

The following health hazards should be noted when handling or choosing a location to plant bloodroot:
