Sanguinaria canadensis is also known as bloodwort,redroot,red puccoon, and sometimes pauson. It has also been known as tetterwort, although that name is also used to refer to Chelidonium majus. 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. In bloodroot, the juice is red and poisonous.Sanguinaria canadensis (bloodroot) is a perennial, herbaceous flowering plant native to eastern North America. It is the only species in the genus Sanguinaria, included in the family Papaveraceae, and most closely related to Eomecon of eastern Asia.
Bloodroot grows from 20 to 50cm (7.9 to 19.7in) tall. It has one large basal leaf, up to 12cm (4.7in) 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 8-12 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 40 to 60mm (1.6 to 2.4in) 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.
Bloodroot is native to eastern North America from Nova Scotia, Canada southward to Florida, United States, and west to Great Lakes and down the Mississippi embayment.
Sanguinaria canadensis plants are found growing in moist to dry woods and thickets, often on flood plains and near shores or streams on slopes. They grow less frequently in clearings and meadows or on dunes, and are rarely found in disturbed sites. Deer will feed on the plants in early spring.
Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate. They also benefit from growing in a medium made richer by the ant nest debris.
The flowers produce pollen, but no nectar. Various bees and flies visit the flowers looking in vain for nectar, for instance sweat bees (Lasioglossum and Halictus), cuckoo bees (Nomada), small carpenter bees (Ceratina), and bee flies (Bombylius). Some bees come to collect pollen, including mining bees (Andrena), which are the most effective pollinators.
Sanguinaria canadensis is cultivated as an ornamental plant. The double-flowered forms are prized by gardeners for their large showy white flowers, which are produced very early in the gardening season. Bloodroot flower petals are shed within a day or two of pollination so the flower display is short lived, but the double forms bloom much longer than the normal forms. The double flowers are made up of stamens that have been changed into petal looking like parts, making pollination more difficult.
The cultivar S. canadensis f. multiplex 'Plena' has gained the Royal Horticultural Society's Award of Garden Merit.
Bloodroot produces benzylisoquinoline alkaloids, primarily the toxin sanguinarine. The alkaloids are transported to and stored in the rhizome. A number of plants in Papaveraceae and Ranunculaceae, as well as plants in the genus Colchicum (family Colchicaceae) and genus Chondodendron (family Menispermaceae), also produce such benzylisoquinoline alkaloids.
Sanguinarine kills animal cells by blocking the action of Na+/K+-ATPase transmembrane proteins. As a result, applying bloodroot to the skin may destroy tissue and lead to the formation of a large scab, called an eschar. Bloodroot and its extracts are thus considered escharotic.
Applying escharotic agents, including bloodroot, to the skin is sometimes suggested as a home treatment for skin cancer, these attempts can be severely disfiguring. Salves derived from bloodroot cannot be relied on to remove an entire malignant tumor. Microscopic tumor deposits may remain after visible tumor tissue is burned away, and case reports have shown that in such instances tumor has recurred and/or metastasized. Similarly, internal use is inadvisable.
Bloodroot was used historically by Native Americans for curative properties as an emetic, respiratory aid, and other treatments.
In physician William Cook's 1869 work The Physiomedical Dispensatory is recorded a chapter on the uses and preparations of bloodroot, which described tinctures and extractions, and also included at least the following cautionary report:
Greater Celandine (Chelidonium majus), a member of the Poppy family (Papaveraceae) was used in Colonial America as a wart remedy. Bloodroot has been similarly applied in the past. This may explain the multiple American and British definitions of "Tetterwort" in 1913.
Bloodroot extracts have also been promoted by some supplement companies as a treatment or cure for cancer, but the U.S. Food and Drug Administration has listed some of these products among its "187 Fake Cancer 'Cures' Consumers Should Avoid". Oral use of products containing bloodroot are strongly associated with the development of oral leukoplakia, which is a premalignant lesion that may develop into oral cancer.
This plant has also been used in medical quackery, as was evidenced by the special product produced by Dr. John Henry Pinkard during the 1920s and 1930s. Some bottles of "Pinkard's Sanguinaria Compound", made from bloodroot or bloodwort, was seized by federal officials in 1931. "Analysis by this department of a sample of the article showed that it consisted essentially of extracts of plant drugs including sanguinaria, sugar, alcohol, and water. It was alleged in the information that the article was misbranded in that certain statements, designs, and devices regarding the therapeutic and curative effects of the article, appearing on the bottle label, falsely and fraudulently represented that it would be effective as a treatment, remedy, and cure for pneumonia, coughs, weak lungs, asthma, kidney, liver, bladder, or any stomach troubles, and effective as a great blood and nerve tonic." John Henry Pinkard plead guilty and was fined $25.00.
Commercial uses of sanguinarine and bloodroot extract include dental hygiene products. The United States FDA has approved the inclusion of sanguinarine in toothpastes as an antibacterial or anti-plaque agent.[non-primary source needed][non-primary source needed] However, the use of sanguinaria in oral hygiene products is associated with the development of a premalignant oral leukoplakia,which may develop into oral cancer. On 24 Nov 2003, the Colgate-Palmolive Company of Piscataway, New Jersey, United States commented by memorandum to the United States Food and Drug Administration that then-proposed rules for levels of sanguinarine in mouthwash and dental wash products were lower than necessary. However, this conclusion is controversial.
Some animal food additives sold and distributed in Europe contain sanguinarine and chelerythrine.
Bloodroot is a popular red natural dye used by Native American artists, especially among southeastern rivercane basketmakers. A break in the surface of the plant, especially the roots, reveals a reddish sap which can be used as a dye.
