Anthelmintic Cathartic Diaphoretic Diuretic Sialagogue Tonic
Seven barks was used by the North American Indians as a remedy for kidney and bladder stones and is still used for these purposes in modern herbalism[254]. It is considered to both encourage the expulsion of stones and to help dissolve those that remain[254]. The roots are anthelmintic, cathartic, diaphoretic, diuretic, emetic and tonic[4, 21, 46, 165, 222, 238]. They are used in the treatment of kidney stones, mucous irritations of the bladder, cystitis, nephritis, enlarged prostate and bronchial afflictions[222, 238, 254]. Excessive doses can cause dizziness and bronchial congestion[238]. The fresh roots are very succulent and can be easily cut, when dry they become very tough and resistant[4]. They are harvested in the autumn and it is best to cut them into short sections before drying them[4, 254]. The scraped bark is used as a poultice on wounds, burns, sore muscles, sprains etc[222]. The bark is chewed in the treatment of stomach and heart ailments[222]. The leaves are cathartic, diuretic, sialagogue and tonic[4].

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.

Propagation
Seed - surface sow in a greenhouse in spring[113]. Cover the pot with paper until the seed germinates[78]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 8cm long, July/August in a frame. Overwinter in a greenhouse and plant out in late spring[78]. Thick growths make the best cuttings, but these should be placed in individual pots[78]. Good percentage[113]. Cuttings of mature wood in late autumn in a frame[200]. Mound layering in spring. Takes 12 months[78]. Division of suckers in late winter[113]. They can be planted out direct into their permanent positions. Leaf-bud cuttings of the current seasons growth in a frame[200].
