Eczema Foot care Salve Skin
A poultice of the pounded, dampened leaves has been applied to the feet to treat sweaty feet[257]. A cold infusion of the plant can be used as a lotion on swollen knees and ankles[257]. The plant has been used as a head wash and to treat scabs and eczema[257].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Hair Insulation Tinder
The seed floss makes an excellent tinder for starting fires, a spark from a flint will quickly ignite it[212]. The seed floss can be used as an insulation in shoes etc[212]. An infusion of the leaves alone, or the leaves and stems, has been used as a hair wash to prevent gray hair[257].

Cultivation details
Prefers a deep moist soil with its roots in the shade[11, 200]. Dislikes poorly-drained heavy clay soils, but grows well in clay if grit is added for drainage[11, 200]. Dislikes light sandy soils[11]. Does well on chalk[1]. Succeeds in acid as well as alkaline soils[200]. When planting out, in order to avoid the disease 'clematis wilt', it is best to plant the rootball about 8cm deeper in the soil. This will also serve to build up a good root crown of growth buds[200]. A twining plant[182]. The leafstalks wrap themselves around twigs and branches for support. When a side of the stalk touches an object, the growth on that side slows down whilst the other side grows at its normal rate - this causes the leaf stalk to entwine the object it is touching[212]. Plants in this genus are notably resistant to honey fungus[200]. Plants seem to be immune to the predations of rabbits[233]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54].

Propagation
Seed - best sown as soon as it is ripe in a cold frame[164, 200]. Sow stored seed as soon as it is obtained in a cold frame. Pre-soak the seed for 12 hours in warm water and remove as much of the tail and outer coat as possible[164]. A period of cold stratification is beneficial[164]. The seed germinates in 1 - 9 months or more at 20°c[164]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for the first winter. Plant out in late spring or early summer, after the last expected frosts. Internodal cuttings of soft to semi-ripe wood, late spring in sandy soil in a frame[200]. Layering of old stems in late winter or early spring[200]. Layering of current seasons growth in early summer[200].
