Taingan-daga is a small variable, prostrate, creeping herb, somewhat pubescent with long, scattered hair, the stems creeping, up to 50 centimeters in length, usually rooting at the nodes. Leaves are trifoliate, with three small heart-shaped leaflets, their petioles 5 centimeters long or less, sessile. Leaflets are obcordate, 0.5 to 1.5 centimeters long and stalkless. At noontime, the leaflets droop like folded umbrellas. At night, the leaflets close and fold together. Flowers are yellow, one to several on each peduncle, subumbellately disposed, nearly 1 centimeters long. Petals are obcordate. Fruits are capsules, hairy, tomentose, subcylindric, 1 to 1.8 centimeters long, divided into minute segments with numerous black seeds the size of sand grains.
– In waste places, open grasslands, etc., from sea level to an altitude of 2,200 meters throughout the Philippines.
– Also occurs in the warmer parts of the Old World.

• Antibacterial: In a study of the traditional medicinal plants from North East India, OC showed antibacterial activity against E. coli. In a study of aqueous extracts of leaves of 46 plants, Oxalis corniculata was one of only 12 that exhibited antibacterial activity against test pathogens.
• Antibacterial: Leaf material was tested for antibacterial activity against three important pathovars of Xanthomas and fourteen human pathogenic bacteria. Results revealed significant antibacterial activity attributed to the presence of phenolic compounds.
• Anti-fertility: Report on the post-coital antifertility activity of the whole plant of Oxalis corniculata in female albino rats.
• Abortifacient: Report on the abortifacient activity of O corniculata.
• Antifungal: Study on the water extract of Oxalis corniculata showed it to be active against Aspergillus niger.
• Anti-Urolithiasis / Antibacterial: Of 17 plants studied, O corniculata was one of six with antibacterial efficacy that showed promising roles in the prevention and cure of urolithiasis.
• Anti-Epileptic: Study showed the methanol extract of Oxalis corniculata increased the monoamines on rat brain, which may decrease the susceptibility to MES and PTZ-induced seizures in rats.
• Antitumor / Antioxidant: Study of ethanol extract of Oxalis corniculata showed significant antitumor and antioxidant activities in Ehrlich ascites carcinoma (EAC) induced in Swiss albino mice. There was effective inhibition of tumor growth in ascitic and solid tumor models.
• Antibacterial / Cream Formulation: Study of aqueous extract OC showed strong antibacterial activity especially with increased extract concentration. A cream formulation showed potential as a topical to protect the skin against S. aureus and E coli.
• Cardioprotective: In vitro studies confirmed that O. corniculata extract could protect the myocardium against ischemic insult and the protective effect can be attributed to its antioxidative and antihyperlipidemic activities.
• Novel Galacto-Glycerolipid / Anti-Amoebic / Anti-Giardia: Study of extracts identified several compounds that showed anti-amoebic activity in axenic cultures of E. histolytica. Of the different compounds, the strongest anti-amoebic activity was found with GGL (galacto-glycerolipid). GGL was also found to be effective in killing Giardia lamblia, another protist pathogen that causes diarrhea in humans.
• Anxiolytic: Study evaluated an ethanolic extract for anxiolytic effect in mice using the open field test, elevated plus maze test, and anti-fighting test. Results suggest anxiolytic activity, consistent with the anxiolytic effects of diazepam.
• Anti-Inflammatory / Antioxidant: Study evaluated the anti-inflammatory and antioxidant activity of a methanol extract of whole plant. There was significant antioxidant activity by scavenging DPPH and NO radicals and TBARS method. There was significant biphasic response in the paw edema induced by carrageenan.
• Antibacterial: In a study of three medicinal plants for antimicrobial activity, the leaves and seeds extracts of Oxalis corniculata showed high antibacterial activity against E coli and Bacillus subtilis.
• Antidiabetic / Antihyperlipidemic: Study evaluated the antidiabetic, antihyperlipidemic, and antioxidant effect of O. corniculata in alloxan-induced diabetic mice. Results showed free radical scavenging, and antidiabetic and antihyperlipidemic effects. Effects were compared to glibenclamide as reference drug.
• Hepatoprotective: Study showed a hydroalcoholic extract of Hummaz (O. corniculata) counteracted the hepatotoxic effect induced by CCl4 and PHH. Although the protection by Silymarin seemed relatively greater, Hummaz can be used as hepatoprotective agent in some liver disorders.
• Gastroprotective / Antiulcer: Study investigated a methanolic extract of O. corniculata in pylorus ligated and indomethacin-induced gastric ulcerations in Wistar rats. Results suggest OC possesses significant antisecretory and antiulcer effects.
