Edible Uses

Edible Parts: Leaves.

Edible Uses: Drink.

Leaves - raw or cooked[9]. They can be used in salads, soups, stews etc[183]. Somewhat bitter due to the presence of tannin in the leaves, though this can be removed by washing the leaves[177]. A cold water infusion of the freshly chopped or dried and powdered leaves is used as a refreshing beverage[161, 183]. Very tasty[168].

Self heal has a long history of folk use, especially in the treatment of wounds, ulcers, sores etc[7]. It was also taken internally as a tea in the treatment of fevers, diarrhoea, sore mouth, internal bleeding etc[4, 222]. In Korea it is used to treat oedema, nephritis, scrofula and goitre[279]. The whole plant is alterative, antibacterial, antipyretic, antiseptic, antispasmodic, astringent, carminative, diuretic, febrifuge, hypotensive, stomachic, styptic, tonic, vermifuge and vulnerary[4, 9, 13, 21, 176, 218]. It has an antibacterial action, inhibiting the growth of Pseudomonas, Bacillus typhi, E. coli, Mycobacterium tuberculi etc[176]. It can be used fresh or dried, for drying it is best harvested in mid-summer[4]. The plant is experimentally antibiotic and hypotensive[218, 222].

Other Uses

Dye; Ground cover.

An olive-green dye is obtained from the flowers and stems[168]. The plant is a good ground-cover in sunny positions or light shade[200].

Cultivation details

Thrives in any damp soil[1], in full sun or in light shade[238]. Plants are apt to become troublesome weeds in turf that is at all damp[1]. Self heal is a good plant for growing in the spring meadow[24].

Propagation

Seed - sow in mid spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed then it can be sown outdoors in situ in mid to late spring. Division in spring or autumn. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
