Cultivation: Succeeds in most soils so long as they are rich and well-drained. Intolerant of winter-wet soils. Requires an open sunny position. This plant is adored by slugs. A greedy plant, inhibiting the growth of nearby plants, especially legumes.

Propagation:
Through seed – sow March/April in a cold frame or May outdoors. Keep moist and in a shady position until germination takes place. The seed has a limited viability so it should be stored in a sealed container at about 3°c[200]. Temperatures above 15°c inhibit germination. The seed usually germinates in 2 – 9 weeks at 15°c[175]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer. Cuttings of basal shoots in April/May, taken before they become hollow at the base, and planted in a cold frame. Division in spring[111] or early autumn.

Edible Uses: Not Known.

Medicinal Uses:
It is one of the important drugs used as indigenous medicine in India, especially in Unani medicine. Its vernacular name is Jadwar.

The roots of the plant are reported to be useful in a variety of ailments such as aconite poisoning, brain diseases, fungal infection, piles and toothache as analgesic and astringent. A number of studies have been done on its phytochemical and pharmacological properties.

Its use in opium addiction is mentioned in some classical literature, which has been verified and validated in morphine-induced physical dependent de-addiction studies. Some species are reported to have been poisonous. Human Poisoning due to Delphinium Species in the Himalayan Region of Nepal: A Case Report Santosh Adhikari et al. JNMA J Nepal Med Assoc. 2020.

Deguelia utilis

Botanical Name: Deguelia utilis
Family: Fabaceae
Subfamily: Faboideae
Kingdom: Plantae
Order: Fabales
Tribe: Millettieae
Genus: Deguelia
Species: D. utilis

Synonyms : Lonchocarpus utilis A.C.Sm. Derris nicou auct Derris utilis (A.C.Sm.) Ducke Lonchocarpus nicou auct Lonchocarpus nicou utilis (A.C.Sm.) A.M.G.Azevedo

Common Names: Barbasco, cube, timbo, nicou, lancepod

Habitat: Deguelia utilis is native to S. America – Brazil, Peru, Ecuador, Colombia, Venezuela, the Guyanas. It grows in both dense, primary rainforest and also in more open areas of secondary growth, often as a relict of cultivation. It is found in a range of conditions, sometimes in soils subject to periodic flooding, often near rivers, in acid to neutral soils.

Discription:
Deguelia utilis is an evergreen shrub or small tree growing up to around 3 metres tall when young, but generally adopting a more climbing habit as it grows older with stems that can climb 15 metres into the surrounding trees.

It is one of the sources of rotenone, an organic insecticide used as a fish and ant poison. It is commonly found in South America. It has a symbiotic relationship with a certain soil bacteria that forms nodules on the roots and fixes atmospheric nitrogen.

CLICK & SEE THJE PICTURES

Cultivation:
A plant of the moist, lowland tropics, usually in areas with year-round rainfall. Succeeds in moderate sun to fairly deep shade so long as the top growth can climb towards the light. Prefers a neutral to acid soil, usually found on more or less clay soils in the wild. In some areas where it grows it is subject to periodic inundation of the soil. Some forms of this plant do not produce seed, probably as a result of long term cultivation with propagation by cuttings. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.

Propagation: Through seeds – Cuttings root easily.

Edible Uses: Not known

Medicinal Uses:
The plant contains some compounds similar to curare. Traditional healers crush the bark until a white milky substance exudes, they take one spoonful of this and retire. Twenty-four hours later they relate their visions to the tribes people.

Other Uses: The roots contain rotenone, which can be used as an insecticide.

Known Hazards: The plant contains rotenone and has been used traditionally as a fish poison- the rotenone kills or stuns the fish making them easy to catch, but the fish remain perfectly edible for mammals. Rotenone is classified by the World Health Organization as moderately hazardous. It is mildly toxic to humans and other mammals, but extremely toxic to many insects (hence its use as an insecticide) and aquatic life, including fish. This higher toxicity in fish and insects is because the lipophilic rotenone is easily taken up through the gills or trachea, but not as easily through the skin or the gastrointestinal tract. The lowest lethal dose for a child is 143 mg/kg, but human deaths from rotenone poisoning are rare because its irritating action causes vomiting. Deliberate ingestion of rotenone, however, can be fatal.
The compound decomposes when exposed to sunlight and usually has an activity of six days in the environment.

Cultivation:
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland). It prefers moist soil.
Prefers a fertile well-drained loam with some shelter at the hottest part of the day. Plants tolerate occasional lows to about -5°c. This species is probably not very hardy in Britain and will probably require greenhouse protection, though it might be possible to grow it outdoors in the mildest areas of the country, especially if it is given the protection of a warm wall. A very variable species. Dioecious, male and female plants must be grown if seed and fruit is required.

Propagation:
Through seed – sow late winter to mid-summer in a greenhouse and only just cover the seed. Germination usually takes place within 1 – 2 months at 20°c. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Softwood cuttings in early summer.

Edible Uses:
Fruits are edible, eaten – raw or cooked.

Medicinal Uses:
The juice of the leaves is applied to areas of the skin affected by scabies.

Other Uses:
A strong fibre is obtained from the stem bark. It is used for making twine and rope. Wood is used mainly for fuel.
