Malapako is a stout, coarse, smooth or somewhat hairy herb, more or less branched, often half-woody, and 0.4 to 1.5 meters high. Leaves are lanceolate, 6 to 15 centimeters long. Flowers are solitary, yellow, axillary, without a stalk or with a very short stalk, borne in the upper leaf axils. Calyx is green. Petals are four, yellow, orbicular-obovate, and about 1 centimeter long. Capsules are green or purplish, clove-like shape, 3 to 5 centimeters long, 5 millimeters thick or less, and 8-ribbed, containing many rounded black seeds. Calyx lobes are persistent, oblong-ovate, and about 1 centimeter long.

– Study of Ludwigia octovalvis yielded thirteen compounds: beta-sitosterol, oleanolic acid, 2alpha-hydroxy ursolic acid, tormentic acid, daucosterol, maltol, luteolin, quercetin, apigenin, methyl brevifolincarboxylate, gallic acid, 3, 4, 8, 9, 10-pentahydroxydibenzo[b, d]pyran-6-one, and ellagic acid.
– Considered astringent, carminative, diuretic and vermifuge.
– Leaves used for tea by the Malay.
– Plant, pulped and steeped in buttermilk, used for diarrhea and dysentery.
– Decoction used as diuretic, vermifuge and purgative; also, used for flatulence.
– As astringent, used for hemoptysis and leucorrhea.
– Mucilaginous leaves used for poulticing headaches and for orchitis and glands in the neck.
– Leaves used for nervous diseases.
– Used for skin diseases.
• Antipyretic: Study was done to evaluate the anti-pyretic potential of a methanol extract of the aerial part of Jussiaea suffruticosa in yeast-induced pyrexia in albino rats. Various doses of MEJS showed significant dose-dependent reduction in normal body temperature and yeast-provoked temperature elevation. The effect was comparable to that of paracetamol.
• Anti-Diarrheal: Study was done to evaluate the anti-diarrheal potential of a methanol extract of J. suffruticosa on experimental models in rats. Results showed a significant reduction in gastrointestinal motility following a charcoal meal in rats. The extract exhibited significant anti-diarrheal potential in all animal models.
• Toxicological Study / Hepatoprotective / immunostimulatory / Cardioprotective: Study evaluated the toxicity profile of an 80% methanolic extract of in BALB/c mice. Results showed no mortality or morbidity in acute and subacute toxicity testing. The extract yielded biologically active principles which may have immunostimulatory, hepatoprotective and cardiovascular protective properties.
• Antioxidant / Antibacterial: Study evaluated twelve extracts of L. octovalvis for their total phenolic content, antimicrobial, and antioxidant activity. There was a strong correlation between total phenolic content and antioxidant activity. Results showed the leaf of L. octovalvis as a potential new source of natural mixture of antioxidant and anti-E. coli O157:H7.
• Chlorophyll a / Anti-Proliferative: Study evaluated the anti-proliferative activity of extracts and active constituent (chlorophyll a; CHL-a) in 3T3-L1 adipocytes. Results showed CHL-a possesses potent anti-proliferative activity, and its apoptotic effects on 3T3-L1 adipocytes are mediated through the activation of CD95 system and AMPK signaling pathway.
