Name “gliricidia” derives from the Lain ‘glis’ (dormouse) and caedere (to kill). The Spanish name “mata-raton” refers to the tree’s rodenticial properties.
As the tree pods hang-dry in the sun, they curl and explode, making a popping cracking sound. A cluster of trees with their pods snapping and popping and falling to the ground, in unison, make a fascinating afternoon of nature’s concoction of sound.
The tree is common in the southern Tagalog areas, shedding leaves around December and flowering February and March. In some areas, the blooming of its pink flowers is so profuse to deserve a comparison with the cherry blossoms.

Kakawati is a smooth, deciduous tree, 3 to 10 meters high. Leaves are 15 to 25 centimeters long with 13 leaflets which are opposite, oblong-ovate, 4 to 6 centimeters long, with a pointed tip and rounded base. Racemes are numerous on leafless branches, containing many flowers. Flowers are pink, 2 centimeters long, with a truncate calyx. The standard is reflexed and pale-yellow in the median part. The pods are narrowly oblong to oblanceolate, 10 to 14 centimeters long, about 2 centimeters wide, containing 6 to 8 seeds.
– Thoroughly naturalized throughout the Philippines in settled areas at low and medium altitudes.
– Planted as an ornamental flowering tree for its beautiful pink flowers.
– Introduced by the Spaniards from Mexico.
• Phytochemical studies have yielded a formosin (an isoflavan, reportedly with anti-tumor capacity), formononetin, gliricidin-6a-gliricidol-9a, medicarpin (pterocarpan), 7,4′-dihydroxy-3′-methoxyisoflavin, 2’O-methylsepiol, tannin, and a trihydroxyflavone.
• Heartwood yielded a stigmastanol glucoside and 3’4-dihydroxy-trans-cinnamic acid octacosylester 2 along with three other known constituents.
• Study yielded two new triterpene saponins (1 and 2), possessing 3beta, 21beta, 24–trihydroxy-22-oxoolean-12-ene as aglycon, together with known aromatic compounds.
• Tannins are considered potentially antidiarrheal, antidysenteric, antimutagenic, antioxidant, bactericidal, hepatoprotective, pesticidal and viricidal.
Leaves, bark, roots.
– Dermatitis, skin itching: Apply juice or decoction of leaves, bark or roots on the skin as antipruritic.
– Fresh leaves applied to the skin as insect repellent.
– As counterirritant: Crush leaves and apply as poultice for rheumatic pains, sprains and closed fractures.
– Sap of bark, leaves and roots have been used for wound healing.
– Treatment of scabies.
– In Guatemala, the bark and leaves are used to treat skin diseases.
– In Guatemala and Costa Rica, bark decoction is used against baterial and protozoal infectons.
– In many folkloric regimens of other countries, used for headache, bruises, burns, colds, cough, fever, fatigue, gangrene, gonorrhea, skin itches and sores; as antidote, insecticide, insect repellent.
– In Panama, decoction of leaves used in urticaria, rash, burns, and erysipelas.
– Wood: Wood is hard and durable used for small housing needs, posts, implement handles and firewood. In the Tagalog areas, popularly used as a living fence.
– Fleas and Ticks: Leaves have a fetid smell; crushed, used to rid dogs of fleas and ticks and cattle, of ticks.
– Plant used as rodent poison.
– The juice from leaves is applied to daily for one week to areas affected by external parasites,
– Insect repellent: In Latin American, used by farmers to repel insects. Leaves are ground up, mixed with water, and the resulting paste use to bathe animals, and repeated every 7 to 14 days, decreasing the infections from tropical warble fly.
• Anti-Pseudomonas: Crude extract of Gliricidium sepium showed potential antipseudomonas drug potential with an in vitro study showing a minimum inhibitory concentration at 1%.
• Anti-Scabies:The study concluded that the “kakawati” preparation is as effective as sulfur lotion in the treatment of scabies.
• Antimicrobial: Study of 10 medicinal plants in Colombian folk medicine, including G sepium, was done screening for antimicrobial activity. The ethanol extracts were all active against S aureus except for J secunda.
• Antimicrobial:A possible alternative in the treatment of non-nosocomial infections: G. sepium was one of ten medicinal plants screened for antimicrobial activity, all of which were found effective against three or more pathogenic microorganisms, corroborating their use in folkloric medicine.
• Saponins: Study yielded three new hederagenin-based acetylated saponins from the fruits of Gliricidia sepium.
• Insecticidal / Nematicidal / Antibacterial: Study showed nematicidal activity against Meloidogyne incognita nematode with 60% mortality; mosquito repellent activity against Aedes aegypti with maximum 78% repellency; and antibacterial activity against E. coli, S aureus, Pseudomonas spp, S typhi and Klebsiella spp with best results against E Coli.
• Antimicrobial / Bark: Study on the antimicrobial activity on the bark of five tree species showed G sepium to have antimicrobial effects against S epidermis, S aureus, P aeruginosa, B pumillus and V cholerae.
• Anti-Scabies: In a study of scabies treatment among selected residents of Titay, Zamboanga, results showed a significant difference between pre-treatment and post-treatment scores after one week. However, there was a noted increase of scabies lesions 2 and 4 weeks after.
• Antimicrobial: Study investigated an ethanolic extract of Gliricidia sepium for antimicrobial activity against gram-positive, gram-negative bacteria, and fungi. Maximum inhibitory activity was between 0.5 and 1 mg ml-1 against bacteria and 2.5 mg ml-1 against fungi.
• Antibacterial / Bark, Flower and Leaf: Study investigated various extracts of bark, flower, and leaf for antibacterial activities against various pathogenic bacteria. Results showed various extracts of flower, bark, and leaves can be used as potential external antiseptic and incorporated into drug formulations.

1. White candlesticks
2. Coconut oil or any cooking oil: 500 cc
3. Kakawati leaves 250 g
1. Clean kakawati leaves thoroughly
2. Chop leaves finely
3. Add 250 g (approximately 1 glass) of finely chopped leaves into 2 glasses of coconut oil.
4. Mix while boiling.
5. Gather leaves on the surface of the oil, then drain using a strainer.
6. Get 4 white candles (‘esperma”) and chop finely.
7. Add to the boiled preparation and mix until all chopped candles are melted.
8. Again, using a strainer, drain and transfer mixture into a clean glass container. Let it cool.
• Tannins: In South America, in times of scarcity, the forage is fed to livestock. Although goats can consume large quantities of plants with tannins, some animals, like cattle and sheep may not tolerate it due to a salivary protein binding factor that binds the tannins.
