Antibacterial Antibiotic Antispasmodic Demulcent Expectorant Homeopathy Hypoglycaemic Warts
The sundew has a long history of herbal use, having been popular for its fortifying and aphrodisiac effects[238]. It relaxes the muscles of the respiratory tract, easing breathing and relieving wheezing and so is of great value in the treatment of various chest complaints[254]. The plant has become quite rare and so it should not be harvested from the wild[254]. The flowering plant is antibacterial, antibiotic, antispasmodic, antitussive, demulcent, expectorant and hypoglycaemic[4, 7, 9, 13, 21, 46, 165, 172, 222, 238]. The plant is used with advantage in the treatment of whooping cough, exerting a peculiar action on the respiratory organs[4]. It is also used in the treatment of incipient phthisis, chronic bronchitis and asthma[4]. Externally, it has been used to treat corns, warts and bunions[257].The plant is harvested in the summer and can be dried for later use[7]. Use with caution[21]. Internal use of this herb causes a harmless colouring of the urine[9]. An extract of the plant contains plumbagin, which is antibiotic against a wide range of pathogens[222, 238]. Because of their protein digesting enzymes, the leaf juice has been used in the treatment of warts and corns[4, 222]. The entire fresh plant, harvested when it is starting to flower, is used to make a homeopathic remedy[232]. It is used mainly in the treatment of coughs[232] and is specific for whooping cough[7].

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.

Cultivation details
Prefers a sandy peaty soil, succeeding in poor soils and bogs[1, 200]. Requires a sunny position[238]. An insectivorous plant, it can survive in nitrogen poor soils because it gets the nutrients it needs from insects[1, 7, 9, 200]. The upper surfaces of leaves are covered with hairs that secrete a sweet sticky substance[7].This attracts insects, which become smeared with it and unable to escape - the plant then exudes a digestive fluid that enables it to absorb most of the insect into its system[7].

Propagation
Seed - best sown thinly as soon as it is ripe into pots of a free-draining soil with some charcoal added and with a layer of finely chopped sphagnum moss on top[175]. Surface sow and keep the compost moist. The seed usually germinates in 1 - 2 months at 20°c[175]. Grow the plants on in the pots for their first growing season, making sure that the soil does not become dry. Divide the plants in the autumn, grow them on in the greenhouse for the winter and plant them out into their permanent positions in late spring.
