Usages médicinaux

• Lady's mantle has a long history of herbal use, mainly as an external treatment for cuts and wounds, and internally in the treatment of diarrhoea and a number of women's ailments, especially menstrual problems [9, 244].
• The herb is alterative, antirheumatic, astringent, diuretic, emmenagogue, febrifuge, sedative, styptic, tonic and vulnerary [4, 7, 9, 21, 46, 165].
• The leaves and flowering stems are best harvested as the plant comes into flower and can then be dried for later use [4].
• The fresh root has similar and perhaps stronger properties to the leaves, but is less often used [4].
• The plant is rich in tannin and so is an effective astringent and styptic, commonly used both internally and externally in the treatment of wounds [4].
• It helps stop vaginal discharge and is also used as a treatment for excessive menstruation and to heal lesions after pregnancy [4, 244].
• Prolonged use can ease the discomfort of the menopause and excessive menstruation [268].
• The freshly pressed juice is used to help heal skin troubles such as acne and a weak decoction of the plant has been used in the treatment of conjunctivitis [244].

Autres usages

Culture

Propagation

• Graine - Semez au printemps sous un chassis .
• The seed usually germinates in 3 - 4 weeks at 16°c [133].
• When large enough to handle, prick the seedlings out into individual pots and grow them on a cold frame for their first winter, planting out in late spring or early summer .
• Division au printemps ou à l'automne .
• The divisions can be planted out direct into their permanent positions, though we find it best to pot them up and keep them in a sheltered position until they are growing away well .
