Food Uses of Purple Loosestrife
Young leaves eaten in small amounts. There are claims that the root is edible, although this is questionable as I can find no reference in the ethnobotanical record. Note: It is illegal to dig up roots without landowner’s consent.
Herbal Medicine Uses of Purple Loosestrife
Purple loosestrife has been used in traditional (folk) medicine as a treatment for diarrhoea, chronic intestinal catarrh, haemorrhoids, eczema, varicose veins and bleeding of the gums REF.
A red hair dye was once made from the flowers REF. The dye can also be used as a food colouring.
The plant is high in tannins, so moderate use of the edible leaves and shoots is advised.
