There is an estimated total of 1200 species of Piper in the pantropical and neotropical regions. Works on Philippine wild Piperaceae have been extensive. Candole (1910) reported 133 species of Piper and 26 of Peperomia; Merill (1923), 115 Piper, 25 Peperomia, and Quisumbing (1930), documented 87 Piper and 21 Peperomia.
Kubamba is an erect, suffrutescent plant, 1 to 2 meters high. Leaves are membranaceous with conspicuous, glandular, brown to black dots beneath, broadly ovate to suborbicular-ovate, 17 to 37 centimeters long, 15 to 32 centimeters wide, the base subpeltate, multiplinerved and equilaterally deeply heart-shaped, the apex with a pointed tip, somewhat hairy on the nerves on both surfaces, and the margins ciliate. Petioles are very long, more or less hairy, 11.5 to 27.5 centimeters long. Spikes are numerous, umbellate, axillary, hermaphroditic, 5.5 to 12 centimeters long, 2 to 3.5 millimeters in diameter. Rachis is smooth. Bracts are stalked, peltate, about 1 millimeter long, with semilunar, triangular disk. Fruit is free, crowded, obovoid-trigonous, 0.75 to 1 millimeter long, about 0.5 millimeter in diameter, glandular, with the apex truncate and umbonate. Stigmas are cuspidate. Stamens are two, 0.2 millimeter long and with very short stalks.
– In damp forests at low and medium altitudes throughout the Philippines.
– Introduced from tropical America.

• Anti-Venom: Phospholipases A2 are important constituents of snake venoms, responsible for their toxic actions. Study showed extracts from P umbellatum and P peltatum showed inhibition of the enzymatic activity of myotoxin 1, a PLA2 from Bothrops asper, and isolated 4-nerolidylcatechol which completely inhibited the enzyme activity of B asper myotoxin.
• Aristolactams / Antioxidant / Antifungal: Study isolated four alkaloids, piperumbellactams A-D from the branches of P umbellatum together with three other known compounds. Some compounds showed a-glucosidase enzyme inhibition, DPPH radical scavenging activity and antifungal activity.
• Antioxidant: In a study evaluating the antioxidant capacity of 14 herbs/spices from Cameroon, P umbellatum led the antioxidant activity on one assay method.
• Essential Oil: Major essential oil constituents of the fruits showed to be linalool (14.4%) and (E)-nerolidol (10.0%); from the leaves, B-pinene (10.8%), B-caryophyllene (28.2%) and (E)-nerolidol (16.5%).
• Anti-Plasmodial: Study of extracts of seven Cameroon plants used by traditional healers showed P umbellatum extract had moderate activity against P falcifarum. Crude methanol extract of leaves showed strong dose-dependent antimalarial activity against P. berghei-infected mice.
• Insecticidal / Anti-Cockroach: Study yielded isoasarone, a compound shown to be capable of causing immediate hyperexcitation and complete inhibition of the cockroach cercal nerve activity.
• Antimicrobial: Study evaluated a methanol extract and fractions of P. umbellatum for antimicrobial activity. Results showed in inhibition of all test microorganisms at the doses used. MIC for the ME and n-hexane fraction was <25mg/ml. Powdered samples extracted in three different solvents showed activity against five pathogenic organisms (Staphylococcus aureus, Klebsiella pneumonia, Escherichia coli, Streptococcus mutans, and Candida albicans).
• Contraceptive Effect: Study evaluated the effect of a methanol extract of leaves on conception and sexual behavior in rodents. The extract protected the rodents from conception from one to three gestational periods. There was dose-related inhibition of regular estrus cycle and ovulation. The contraceptive effect may be due, in part, to secondary metabolites which included phenols and saponins.
• Anti-Cancer / Anti-Inflammatory: Study evaluated the evaluated the anticancer (in vitro antiproliferative activity and in vivo Ehrlich solid tumor model) and anti-inflammatory (carrageenan induced inflammation model) activities of a standardized dichlormethane extract of P. umbellatum leaves. Treatments showed no toxicity. Results showed reduced paw edema and leukocyte migration suggesting that the anticancer activity could involve antiproliferative and anti-inflammatory effects.
