Soro-soro is an erect, shrubby, branched, fleshy, cactus-like plant growing to 2 to 4 meters. Trunk and older branches are grayish and cylindric; medium branches slightly twisted and stout, fleshy, 4- or 5-angled or winged, the younger ones usually 3-winged, the wings lobulate, with a pair of stout, sharp, 2- to 4-millimeter long spines rising from the thickened bases of each leaf or petiole-scar. Leaves, arising from the sides of wings towards the end of the branches, are fleshy, oblong-obovate, 5 to 15 centimeters long; in young plants, longer pointed or blunt at the tip. Cymes are short, solitary in the sinuses, and usually of 3 involucres. Involucres are green or pale yellow, about 6 millimeters in diameter, with the lobes fimbriate.

- Cultivated in gardens as a hedge plant.
- Nowhere spontaneous.
- Also occurs in India to Malaya.

- Studies have yielded euphorbon, resin, gun caoutchouc, malate of calcium, among others.
- Phytochemical studies have yielded triterpenes like nerifolione, cycloartenol, euphol, euphorbiol, nerifoliene, taraxerol, b-amyrin among others.
- Fresh latex yields 10.95% solid with 18.32% total resinous matter, and 24.50% and 16.23% of total diterpene and triterpene respectively.
- Phytochemicals yielded steroidal saponin, reducing sugar, tannins, flavonoids in the crude extract.

- Considered purgative, rubefacient, expectorant.
- Leaves considered diuretic.
- Root is considered antiseptic.
- Latex considered purgative, diuretic, vermifuge and antiasthma.
- Studies have reported cytotoxic, antiarthritic, anti-inflammatory, wound healing and immunomodulatory properties.

Anesthetic Activity: Both the alcoholic and aqueous extracts from the fresh stem of E nerifolia revealed significant anesthetic activity on intradermal wheal in guinea-pig and foot-withdrawal reflex in frog. (1)
Radioprotective / Cytotoxic: Study isolated Euphol from the triterpenoidal sapogenin fraction of E nerifolia leaf which exerted moderate antioxidant activity with highly significant reduction of gamma radiation-induced chromosomal aberrations. It also showed cytotoxic activity on melanoma cell lines. Results provide scientific basis for claimed anticarcinogenic use. (2)
Wound Healing: In a research for wound healing drugs, E nerifolia was one of the Ayurvedic medicinal plants from Ayurvedic medicinal plants found to be effective in animal models. (3)
Wound Healing / Latex: Aqueous extract of latex of E. nerifolia in surgically produced cutaneous wounds in guinea pig exhibited a facilitation of the healing process as evidenced by an increase in tensile strength, DNA content, epithelization and angiogenesis.
Triterpene: Study isolated a new triterpene from the leaves and stems of Euphorbia nerifolia – glut-5(10)-en-1-one. (4)
Antifungal: Study on the antifungal activity of ethanolic extracts of medicinal plants against Fusarium
oxysporum showed various extracts with inhibition of mycelial growth. However, the bark of E nerifolia exhibited absolute toxicity against the test fungus. (5)
Dermal Irritant / Anti-Inflammatory: The presence of polycyclic diterpene esters in Euphorbia plants sap makes it highly irritant and corrosive causing skin burning, a property that discourages it use despite its many therapeutic potentials. Study of topical latex showed anti-inflammatory activity attributed to the presence of triterpenes euphol, nerifoliol, and cycloartenol. (8)
Chemoprotective Against Liver Carcinogenesis: In a study of DENA-induced liver cancer in mice, EN extract significantly restored the antioxidant enzyme level in the liver and exhibited significant dose-dependent protective effect against DENA induced liver toxicity, mainly attributed to the antioxidant property of the extract. (9)
Free Radical Scavenging / Antioxidant: Study of ethanolic extract of leaves showed EN 0ssesses antioxidant properties and could serve as free radical inhibitors or scavengers. (10)
Psychopharmacological Effects: Leaf extract of EN significantly reduced apomorphine-induced stereotype in mice, devoid of cataleptic effect, suggesting a specific dopaminergic receptor modulating activity. Results indicated anti-anxiety, anti-psychotic, and anticonvulsant activity of the leaf extract in mice and rats. Phytochemicals yielded steroidal saponin, reducing sugar, tannins, flavonoids in the crude extract. (11)
Hepatoprotective: Study of a saponin fraction isolated from the leaf of E. neriifolia on CCl4-induced hepatotoxicity in rat showed hepatoprotection comparable to silymarin. (12)
Renoprotective: Study evaluated the tissue protective effect of an isolated flavonoid and hydroalcoholic extract of E. neriifolia leaves against N-nitrosodiethylamine (DENA) induced renal carcinoma in albino mice. Results showed highest renal-protective activity among all the pretreatment groups. (15)
Diuretic : Study evaluated the diuretic effect of a leaf extract of Soro-soro. Results showed a diuretic effect, more effective with higher concentrations, and more significant than control Diuspec. (16)
