Alterative Anodyne Anthelmintic Antiinflammatory Diuretic Eczema Purgative Stimulant
Knotted figwort is a plant that supports detoxification of the body and it may be used as a treatment for various kinds of skin disorders[254]. The whole plant is alterative, anodyne, anti-inflammatory, diuretic, mildly purgative and stimulant[4, 9, 21, 165]. It is harvested as the plant comes into flower in the summer and can be dried for later use[4]. A decoction is applied externally to sprains, swellings, burns, inflammations etc, and is said to be useful in treating chronic skin diseases, scrofulous sores and gangrene[4, 254]. The leaves can also be applied fresh or be made into an ointment[4]. Internally, the plant is used in the treatment of chronic skin diseases (such as eczema, psoriasis and pruritis), mastitis, swollen lymph nodes and poor circulation[238]. It should not be prescribed for patients with heart conditions[238]. The root is anthelmintic[9].

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[238]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed then it can be sown outdoors in situ in the autumn or the spring. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
