Buñga-buñga is a spreading or prostrate, erect, more or less branched, glabrous, succulent
herb, 0.4 to 1.4 meters high. The ultimate branches are covered with two lines of hairs on the internodes, and the flowering ones are ascending. Leaves are stalkless, simple or pinnately compound, the leaflets elliptic,
crenate or obscurely toothed, usually about 2.5 to 7 centimeters long, thick and succulent. Flowers are minute, 5 to 7 millimeters long, paniculate, pendulous, white, and crowded in very short, axillary heads. Sepals are lanceolate, 2 to 2.5 millimeters long. Fruit is dry and flattened, broadly obcordate utricle, containing one seed.
- Very common weed in open, usually wet places throughout the Philippines, in settled areas at low and medium altitudes.
Entire plant; use fresh.
May be collected the whole year round.
- High in antioxidant carotene.
- Phytochemical studies yielded B-carotene, ricinoleic acid, myristic,
palmitic, stearic, oleic and linoleic acids, a-spiraterol, uronic acid,

- Study of phenolic and
- Slightly tart tasting, cooling, antiphlogistic-analgesic , antidermatosis, antiseptic.
- Considered febrifugal, galactagogue, abortifacient.
• Some places, leaves and young shoots eaten as vegetables.
• In Ceylon, largely eaten as vegetable.
• In Africa, used
for relishes, sauces and soups.
• Considered a famine plant.
• Poultice of pounded fresh
material to sprains, burns and eczema.
• Carbuncle, erysipelas.
• Used as a wash for eyes.
• U used for treating acne vulgaris, dyspepsia,
• Decoction used for nausea, vomiting, diarrhea, dysentery, cough,
bronchitis and diabetes.
• In West Tropical Africa, used as poultice for boils.
• In Sri Lanka,
used for cystitis, gonorrhea, snake bite. Also, used by mothers to increase flow of milk.
• In Ghana, salted
decoction used for hematemesis.
• In India, used
for gastrointestinal problems; also as cholagogue, abortifacient and
febrifuge. Also, used for snake bites.
• In Nigeria, for
headaches and vertigo.
• In Taiwan, for
hepatitis, bronchitis, asthma.
• Used for animal feed supplement.
• Antimicrobial / Wound Healing
on extract of leaves showed significant results in different parameters
of wound healing. The presence of sterols was also confirmed. (2)
• Hepatoprotective: A study on the hepatoprotective effects of Taiwanese herb Alternanthera sessilis on liver damage induced by various hepatotoxins showed hepatoprotective
effects with a reduction of elevation of SGOT and SGPT . (3)
• Ionone Derivatives / Antimicrobial: Chloroform extract of dried leaves yielded
a mixture of diasteromers of a new ionone derivative with low activities
against Pseudomonas aeruginosa and Trichophyton mentagrophytes. (4)
• Antioxidant: (1) Study
showed ethanol extract to have 70% free radical scavenging activity.
(2) Study concludes Alternanthera sessilis showed potent radical-scavenging activity and metal ion chelating activity.
• Antidiabetic: Study
of aqueous extract of aerial parts showed significant dose-dependent antidiabetic activity
with lowering of blood glucose concentration, glycosylated hemoglobin, LDL, total cholesterol. (6)
• Antibacterial: The antibacterial effect of leaves and internodal-segments derived calli of A. sessilis was evaluated against Proteus vulgaris, Strep pyogenes, B subtilis and Salmonella typhi. the ethanolic extracts of leaves and leaves-derived calli were more effective against the selected bacterial than other solvents. Plants extracts showed antibacterial activity against Gram negative P. aeruginosa and Gram positive Staph epidermis. (7)
• Hematinic Activity: Study
showed that Lupo (A. sessilis) has hematinic activity particularly in iron deficiency anemia.
Results suggest AS is a potential drug for augmentation of hemoglobin and serum ferritin in iron deficiency anemia. (8)
• Antipyretic Activity: Study
the ethanol extract of aerial parts of Alternanthera sessilis has dose-dependent antipyretic activity. (9)
• Antibacterial / Antifungal: Plants extracts showed antibacterial activity against Gram negative P. aeruginosa and Gram positive Staph epidermis.
Plant also showed antifungal activity against yeasts S. cerevisiae and Candida albicans.
• Nootropic / Memory Enhancing: Study evaluated the nootropic potential (memory enhancing effects) of methanolic extracts of leaves of A. sessilis and Clerodendrum infortunatum. The higher doses of both extracts exhibited promising nootropic potential, with C. infortunatum showing greater memory enhancing effect.. (14)
• Antidiabetic: Study
investigated the antidiabetic potential of three fractions of crude ethanol extracts in high fat diet and STZ-induced diabetic rats. The red ethyl acetate fraction showed the most potent antihyperglycemic effect with higher pancreatic insulin content and pancreatic total dismutase activity. Results suggest a potential antidiabetic agent for T2DM. (16)
• Anti-Inflammatory: Study
investigated leaf extracts for anti-inflammatory activity by carrageenan-induced rat paw edema method. Extracts showed considerable dose-dependent activity, with the chloroform extract showing higher activity. (17)
• Toxicity Study / Antidiabetic: Study
on extracts from A. sessilis, S. cumini and A. bilimbi appeared safe, with no untoward effects on the kidney and liver when used as treatment for diabetes. (18)
• Silver Nanoparticles Biosynthesis: Study
evaluated the use of aqueous extract in producing silver nanoparticles from silver nitrate aqueous. Phytochemical analysis yielded alkaloid, tannins, ascorbic acid, carbohydrates and protein which served as effective reducing and capping agents for converting silver nitrate into nanoparticles. (19)
