Derris, Paraderris elliptica, is an evergreen climbing shrub with woody stems that grow up to 16m long and commonly found in East Asia. There is no known edible uses of Derris but it has several medicinal uses. It is used traditionally to eliminate microorganisms that cause diseases. It is applied to abscesses and used in the treatment of leprosy. It is sometimes used to cause abortion and increase menstrual flow in women. The root contains a toxic substance known as Rotenone, which is used as an insecticide.

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Abortifacient  Antiseptic  Antitumor  Blood tonic  Emmenagogue  Leprosy  Parasiticide

The plant is traditionally used for antisepsis and is applied to abscesses and against leprosy and itch, and sometimes as an abortifacient[303 ]. The roots are used as emmenagogue[303 ]. The stems are a blood tonic[303 ]. Rotenone, the active insecticidal ingredient found mainly in the root, has been evaluated as a potential antitumor agent[303 ]. It is broadly cytotoxic, the growth-inhibiting effect has been demonstrated both with cultured cells and experimental tumours[303 ]. The roots also contain tubaic acid (0.01% of air-dried root). This compound has shown anti-microbial activity, inhibiting the growth of Bacillus subtilis, Staphylococcus aureus and Escherichia coli at high concentrations[303 ].

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.

Other Uses

Insecticide  Parasiticide

The powdered root is widely used as an insecticide[303 ]. It is effective against a range of horticultural pests, such as aphids and caterpillars, and also against external body parasites like ticks, lice, fleas and flies[418 ]. The root can be up to 2cm in diameter and more than 2 metres long[418 ].

Cultivation details

A plant mainly found in humid, lowland tropical areas, though it can also be grown at elevations up to 1,500 metres. It grows best in areas where annual daytime temperatures are within the range 24 - 30°c, but can tolerate 20 - 36°c[418 ]. It prefers a mean annual rainfall in the range 1,800 - 3,500mm, but tolerates 1,400 - 5,000mm[418 ]. It can survive dry periods of up to 4 months[418 ]. Prefers a position in full sun or in light shade[418 ]. Succeeds in most well-drained soils of at least moderate fertility[418 ]. Prefers a pH in the range 5.5 - 7, tolerating 4.3 - 8.6[418 ]. Plants can commence flowering when about 18 months old[303 ]. The yield of dried roots is 1,100 - 1,800 kg/ha, occasionally up to 3,000 kg/ha, particularly when plants are trellised[303 ]. There is a danger of soil erosion during the first few months after planting and again after harvesting, therefore land suitable for this crop should either be flat or only slightly sloping[418 ]. Several cultivars (mostly clones of this vegetatively propagated crop) are widespread in cultivation and have bean selected for high rotenone content (13% of the roots)[317 ].
