Ecology and cultivation: Naturalised in tropical countries.
A small climbing tropical vine with alternately compound leaves, indigenous to Indonesia but also growing in Surinam.
The flowers are small, pale, violet to pink and arranged in clusters.
The fruit (a pod) is flat and truncate – shaped (1Â½ – 2″ long).
This seedpod curls back when it opens to reveal the seeds.
Copiously branched climber with slender branches; leaves alternate, pinnately compound with numerous deciduous leaflets; flowers small, in dense racemes on axillary peduncles or short branches; pods 2.5-3.7 by 1.0-1.25 cm; seeds bright scarlet and black or whitish or black or mixed black and white, large like pea.
The small, hard, brilliant red seeds with a black spot are very toxic due to the phytochemical abrin (consisting of 5 glyco-proteins); a single seed if broken, can cause blindness or even death if ingested.
Abrin is a ribosome – inactivating protein (it blocks protein synthesis) and is one of the most deadly plant toxins known.
Fortunately, the toxin is only released if the seeds are broken (and swallowed) but this is unlikely since they have a hard seed coat!
Phenology: Flowering: August and September; Fruiting : January to March (even up to May).
USDA zone 9 – 11.
Can be planted in the spring up to zone 7 as an annual.
These seeds germinate more consistantly if scarified; soak overnight in hot water or until they swell. Sow swollen seeds immediately in seeding mix. Donâ€™t overwater or allow to dry out.
Full sun / partial shade, well – drained moist soil.
Plant in frost free spots.
Chemical contents: Root and Leaf: glycyrrhizin, isoflavanquinones, abrusquinone A, B & C; leaves taste sweet and roots less so; roots also contain precol, abrol, abrasine and precasine. Seed: poisonous, principal constituents being ‘abrin’; a fat-splitting enzyme, haemaagglutinin, urease; alkaloid (abrin), a glucoside (abralin) and a small quantity of fatty oil have also been isolated from seed. Pharmacologically,abrin is considered to be intensely poisonous. Besides abrin, a seed contains hypaphorine, two steroidsÂone oily and the other crystalline- Î²-sitosterol, stigmasterol, 5 B-cholanic acid, abricin, abridin, cholesterol, lectins and toxic proteins.
Medicinal Aplication & Uses:
In Traditional medicinal applications :Leaves, roots and seeds are used.
The seeds are used as a contraceptive, to treat diabetes and chronic nephritis.
The root is used to induce abortion against abdominal discomfort, gonorrhoea, jaundice and haemoglobinuric bile.Also traditionally used to treat tetanus and to prevent rabies.
Jequirity seeds have been used medicinally in the past as a contraceptive, abortifacient, and as a treatment for chronic conjunctivitis. However, they are so poisonous that even external application is no longer justifiable. Even small amounts brought into contact with an open wound can prove fatal. The leaves and roots contain glycyrrhizin and can be substituted for licorice. The leaves have been used in the Ayurvedic tradition in the treatment of asthma, bronchitis, sore throats, dry coughs and other chest conditions. They have been used in Chinese medicine to treat fever. Externally the leaves are used for sciatica, hair loss, skin disease, leprosy, nervous debility and the seeds for paralysis.
