Bloodroot-Flower-2Bloodroot Flower

Bloodroot is a variable species growing from 20 to 50 cm tall, normally with one large, sheath-like basal multi-lobed leaf up to 12 cm across. The flowers are produced from March to May, with 8-12 delicate white petals and yellow reproductive parts. The flowers appear over clasping leaves while blooming. 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 lump these different forms into one highly variable species. Bloodroot stores sap in an orange colored rhizome, that grows shallowly under or at the soil surface. Over many years of growth, the branching rhizome can grow into a large colony. Plants start to bloom before the foliage unfolds in early spring and after blooming the leaves expand to their full size and go summer dormant in mid to late summer.Bloodroot-Flower

Bloodroot grows throughout the mid to eastern states of the U.S. east of the Mississippi and from southern Canada to the northern half of Louisiana and Georgia. 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.

Toxic Principle:
The red-colored latex from this plant contains several alkaloids similar to those found in the Opium Poppy, and include sanguinarine, chelerythrine, protopine, and homochelidonine, as well as resins. 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. All parts of the plant are poisonous but the toxins are most highly concentrated in the root after leaves are completely open. The active alkaloid levels vary greatly between regions as well as populations

Poisoning Symptoms include:
Skin may destroy tissue and lead to the formation of a large scab. Depending on the toxicity level if ingested it could lead to overdose.
