Edible Uses
Edible Parts: Leaves Seed Stem
Edible Uses:
Young leaves - cooked[8, 22, 46, 61]. A bitter taste, especially if the older leaves are used[105, 183]. The leaves are usually cooked in at least one change of water in order to reduce the bitterness[183]. Leaves can also be dried for later use[12]. The leaves have a much milder flavour when they are first produced in early spring[K]. Young stems - cooked[257]. Seed - raw or cooked[102, 172]. The seed can also be ground into a powder and used to make a gruel or added to cereal flours when making bread etc[102]. It is rather small and fiddly to harvest.

A tea made from the roots has been used in the treatment of jaundice, whooping cough, boils and bleeding[4, 257]. An infusion of the root has been used as a wash, especially for children, to treat skin eruptions[257]. One report says that the root has been used as a contraceptive to stop menstruation[257]. The root is harvested in early spring and dried for later use[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.
