Prunella vulgaris grows 5 to 30cm high (2-12inches), with creeping, self-rooting, tough, square, reddish stems branching at leaf axis.
The leaves are lance shaped, serrated, and reddish at tip, about 2.5cm (1 inch) long and 1.5cm (half an inch) broad, and growing in opposite pairs down the square stem. Each leaf has 3-7 veins that shoot off of the middle vein to the margin. The stalks of the leaves are generally short, but can be up to 5cm (2 inches) long.
The flowers grow from a clublike, somewhat square, whirled cluster; immediately below this club are a pair of stalkless leaves standing out on either side like a collar. Flowers are two lipped and tubular. The top lip is a purple hood, and the bottom lip is often white; it has three lobes with the middle lobe being larger and fringed upwardly. Flowers bloom at different times depending on climate and other conditions, but mostly in summer (from June to August in the USA).
Self-heal propagates both by seed and vegetatively by creeping stems that root at the nodes.
Heal-all is a perennial herb found throughout Europe, Asia and North America, as well as most temperate climates. Its origin seems to be European, though it has been documented in other countries since before any history of travel. In the Republic of Ireland it is currently abundant in the west in the counties Galway and Clare, the southwest in Kerry, the south coast, and is also found around the central basin of Ireland. It is often found growing in moist areas, waste ground, grassland, woodland edges, and usually in basic and neutral soils.
Heal-all is edible, and can be used in salads, soups, stews, and boiled as a pot herb. The Cherokee cooked and ate the young leaves. The Nlaka'pamux drank a cold infusion of the whole plant as a common beverage. The plant contains vitamins A, C, and K, as well as flavonoids and rutin.
Topically, a poultice of the plant is applied to irritated skin, as a disinfecting agent and to pack wounds in the absence of other wound-care material. It was considered by the Chinese to "change the course of a chronic disease".
The plant's chemical constituents include betulinic acid, D-camphor, D-fenchone, cyanidin, delphinidin, hyperoside, manganese, lauric acid, oleanolic acid, rosmarinic acid, myristic acid, rutin, linoleic acid, ursolic acid, beta-sitosterol, lupeol, and tannins.
