Sorrel


Sorrel

Some 200 species of annual, biennials, and perennials makes up this genus, which ranges throughout northern temperate regions. Rumex scutatus is one of the few species with any merit as an ornamental, though it may be difficult to eradicate when well established. Rumex crispus (curled dock) and R. obtusifolius (broad-leaved dock, lapathum), long used to treat skin complaints, are similar in constituents, containing laxative atnrhquinones; they stimulate bile flow and trigger the excretion of toxins. Rumex crispus gained ascendency among 19th century American physiomedicalists and predominates in modern practice. The roots of R. aquatica (water dock) are powdered as a dentifrice and used internally in similar ways to R. crispus. According to Pliny, Julius Caesar's soldiers were cured of scurvy by the use of herba britannica (since identified as R. aquatica). Rumex acetosella (Sheep's Sorrel) is best known as an ingredient of "essiac", a native American anti-cancer remedy that also includes Arctium lappa (See, Burdock), Rheum palmatum (See, Chinese Rhubarb), and Ulmus rubra (See, Slippery Elm). Most species contain oxalates, similar to those found in spinach and rhubarb. Oxalates are poisonous in excess, especially for those with a tendency to rheumatism, arthritis, gout, kidney stones, and hyperactivity. They are also acidic, which may affect sensitive teeth. In the past, young leaves of several species of Rumex were picked as pot herbs. Culpeper regarded docks as "exceedingly strengthening to the liver and as wholesome a pot herb as any" (The English Physician Enlarged, 1653). Most people today would find docks unpalatable, but sorrels remain popular.

Sorrel takes its name from the French word surele, which means "sour". This acidic herb was often eaten by Egyptians and Romans to counteract and overly rich diet. Pliny the Elder, a noted Roman scientist, wrote that those who carried sorrel on their person were protected from scorpion stings. The fresh or dried leaves of the sorrel plant have astringent, diuretic, and laxative properties, and are also used to treat fevers and scurvy.

Clump-forming perennial with pale green stems and sagittate leaves, to 15cm (6in) long. Red-brown flowers are borne in slender, loose spikes from early summer, followed by tiny, hard fruits.
