    The leaves are styptic[240]. They are dried and applied as a powder to cuts, sores and the ruptures caused by leprosy[272], The powder absorbs the moisture of the disease and forms a layer that is removed after 1 – 2 days[272]. An effective cure for most cuts and sores, though it does not effect a complete cure for leprosy[272]. The leaves are also used externally in the treatment of ague[240, 243].

    A paste of the leaves is used as a poultice to remove thorns from the skin[272]. A paste made of the leaves mixed with equal amounts of Bidens pilosa, Drymaria cordata, Galinsoga parviflora and the rhizome of Zingiber officinale is used to treat snakebites[272].

Cultivation & Habitat

Seed – sow late winter or early spring in a warm greenhouse and only just cover the seed. Prick out the seedlings when large enough to handle and plant out after the last expected frosts[200]. Seed can also be sown in situ in the spring and, for earlier blooms, it is possible to sow it in late summer or early autumn, though it will need to be overwintered in a warm greenhouse[200].
Succeeds in full sun in a sheltered position in any reasonably fertile moisture-retentive soil that does not dry out in the summer[200]. Plant vigour and flowering periods are much reduced on dry soils[200]. This species is not frost hardy, though it can be grown as a summer annual in Britain[200]. The fresh plant is malodorous[200].
