Jatropha curcas Linn., is a member of the Euphorbiaceae family. It is a deciduous, succulent, monoeious shrub or small tree which can reach up to 8 m tall. The stems arise from a thich, perennial rootstoch, with watery to whitish latex. The bark is smooth, grey or reddish, shiny and peeling off in papery scales. The leaves are alternate, simple, stipules are minute; petiole 10 – 20 cm long, glabrous; the blade is broadly ovate in outline, usually shallowly 5-lobed, measuring about 7-14 x 5.5 – 14 cm, base shallowly or deeply cordate, apex acute, margins entire, glabrous, 5 – 7-veined from the base. The inflorescence a terminal or axillary umbel-like cyme, often paired, with a solitary female flower terminating each major axis and many male flowers on lateral branches; peduncle up to 5 cm long, hairy; bracts elliptical-lanceolate, measuring about 1 cm long, acuminate. The flowers are unisexual, regular, greenish yellow; male flower has ovate calyx lobes, measuring about 2mm long, petals fused in lower half, lobes oblong to ovate measure 3 mm long, disk composed of 5 free flands, stamens 8, in 2 distinct whorls, the 5 outer fused at the base, the 3 inner with filaments completely fused. The female flower has ovate-lanceolate calyx lobe measuring about 4 – 5 mm long, hairy, petals 6 mm long, free, disk composed of 5 free glands, ovary superior, ovoid-ellipoid, 3-celled, styles 3, fused at base, stigma 2-lobed, staminodes 10. The fruit is a broadly ellipsoid capsule measuring about 2.5 – 3 cm x 2 cm, smooth-skinned, initially fleshy and green, turning yellow and eventually dry and black, late dehiscent, 3 seeded. The seeds are ellipsoid, measuring about 1 – 2 cm long, mottled black and coarsely pitted. [5]


It is native of tropical America and now it is widespread. It is now in cultivation in many tropical third world countries with the advent of biodiesel. [3]

Plant Use

Jatropha curcas is used medicinally by many communities where it grows wild or cultivated. Amongst the reputed use is to arrest bleeding and promote healing of cuts and wounds. For this the latex is being applied over the lesion. The roots are used to expel intestinal worms, treat gonorrhoea and snake bites and insect stings. 

Recently, the plant had been promoted for the production of biodiesel in many developing countries including Malaysia. [5] [7] [8]

Toxic Parts

Whole plant. [1]


Jatrophin (curcin), a violent purgative that stimulates bowel movement, a dermatitis producing resin, a purgative oil, and a glycoside. The poison kills by interfering with the synthesis of protein in intestinal wall cells. The seeds can be eaten if thoroughly roasted to remove the poison. [1] [2] [4]

Risk Management

In the past J. curcas has been used as live fencing in villages, but today it is not a popular plant in urban and rural gardens anymore. It only poses dangers in areas where it is being grown in plantations for the production of biodiesel. Workers of such plantations should be made aware of the dangers of this plant and should be instructed to be cautious when handling them. [5]

Clinical Findings

Reaction time is between 15 to 20 minutes. Difficulty in breathing, sorethroat, bloating, dizziness, vomiting, diarrhoea, drowsiness, dysuria, and leg cramps. The abdominal symptoms of intense pain, nausea, vomiting, and diarrhoea may appear within an hour after ingestion. These symptoms had been attributed to the presence of cucanoleic acid in the oil.  In severe poisoning, muscular spasms and collapse may ensue and may even be fatal. Childrean are especially vulnerable because of the pleasant-tasting seeds. [1] [2] [9]


Gastric lavage is often done unless vomiting has been extensive. Treated with bismuth subcarbonate and magnesium trisilicate to protect the stomach. There is no known antidote for curcin. There has not been any report of fatality published. All patients recovered well after conservative and supportive therapy. [1]
