Cholagogue Demulcent Diuretic Laxative Refrigerant Urinary Vulnerary
Pellitory of the wall has been valued for over 2,000 years for its diuretic action, as a soother of chronic coughs and as a balm for wounds and burns[254]. In European herbal medicine it is regarded as having a restorative action on the kidneys, supporting and strengthening their function[254]. The whole herb, gathered when in flower, is cholagogue, slightly demulcent, diuretic, laxative, refrigerant and vulnerary[4, 7, 61, 165, 238]. It is an efficacious remedy for kidney and bladder stones and other complaints of the urinary system such as cystitis and nephritis[4, 238, 254]. It should not be prescribed to people with hay fever or other allergic conditions[238]. The leaves can be usefully employed externally as a poultice on wounds etc[4]. They have a soothing effect on simple burns and scalds[7]. The plant is harvested when flowering and can be used fresh or dried[238].

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.

Propagation
Seed - sow spring or autumn in a cold frame. Prick out the seedling when they are large enough to handle and plant them out in the summer. If you have sufficient seed then it can be sown in situ in autumn or spring. Division in spring. 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.
