Trema derives from the Greek word for hole, alluding to the pitted seeds. Orientalis is Latin for orient.

Anabiong is a small tree, 5 to 8 meters high, with elongated branches. Leaves are distichous, the upper surface rough; the lower, pale and covered with soft dense hairs, oblong-ovate to lanceolate, 8 to 15 centimeters long, with the base frequently unequal, broad and heart-shaped, and the apex long and thinly pointed, and prominently 3-nerved with finely toothed margins. Cymes are dense, hairy, 1 to 2.5 centimeters long. White flowers are numerous, about 3 millimeters long. Fruit is ovoid, about 3.5 centimeters long.

- In deserted clearings, thickets, and second-growth forests, often abundant, and found throughout the Philippines, at low and medium altitudes, in some places ascending to 2,000 meters.
- Also occurs in India to southern China and southward to northeastern Australia and Polynesia.

- Bark contains a little tannin.
- Study isolated three new compounds (dihydrophenanthrenes and phenyldihydroisocoumarin) from the extracts of trunk bark and root bark.
- Study yielded the presence of tannins and phenolic compounds, fixed oils, fats, phytosterols, and flavonoids.
- Study yielded 8 compounds: ampelopsin F, (-) epicatechin, (+)-catechin, (+) syringaresinol, cinnamic acid among others.

- Dye: The bark tannin used in roughening and coloring fishing lines.
- Veterinary:
Leaf decoction used to deworm dogs.
- Fodder:
Leaves, pods, and seeds used as fodder. In the Philippines, fed to cattle, goats, and water buffalo. High fiber content and toxins limit the use of leaf meal in feeds—the limitation can be overcome by extracting protein from the leaves. (1
- Fuel:
Coppices to provide for firewood and charcoal. (1
- Fiber: Appropriate for paper and pulp production. Paper has good tensile strength and folding endurance. (1


Ethnobotanical Study / Blood Pressure Lowering:
Trema orientalis was one of 33 species of plants used for treatment of hypertension. Used as a leaf decoction, its effect was attributed to polyphenols, potassium retention and the promotion of diuresis. (4)
Anti-Convulsive Effect:
Study of a methanol extract from dried leaves showed anticonvulsive activity on tonic flexion and tonic extension. (6)
Glucose-Lowering: Study was done on the glucose-lowering effect of the aqueous stem bark extract in normal and streptozotocin-induced diabetic rats. Results showed T. orientalis stem bark extract significantly reduces blood glucose in STZ-induced diabetic rats by a mechanism different from the of sulfonylurea agents. (7)
Chromium and Nickel Tolerance: Callus from contaminated and uncontaminated sources of Trema orientalis were tested in vitro for tolerance to chromium and nickel. Results showed seeds from contaminated sites were tolerant to chromium and nickel, suggesting a potential for use in sustainable revegetation programmes on chromiferous mine wastes. (9)
Antibacterial / Bark Extracts: Study evaluated the antibacterial efficacy of aqueous bark extracts of T. orientalis on six selected bacterial strains. Results showed the selected bacterial strains were highly susceptible to the test materials, and corroborates its application in traditional medicine. (10)
Reinforcement of Jute Pulp with Trema Orientalis Pulp: The addition of jute fiber pulp to the T. orientalis pulp increased tear strength. The pulp blends showed increased sheet density. Tensile index and burst index of blended pulp increased with beating degree and proportion of T. orientalis increased. (1
Iron Chelating / Antiradical Activity / Leaves: A methanol soluble fraction extracted from leaves showed antiradical activity of 69.73% on a DPPH assay, almost similar to ascorbic acid. Iron chelating activity was 40.74%. The results suggest a potential for processing industries and a good source for an iron chelator. (1
Black Powder for Blasting and Fireworks Purposes: Study of generated flames exhibited characteristics of black powder used for blasting purposes. The flames from ignition of black powder of Trema orientalis were comparable to that of foreign black powder. Results showed a potential for use of T. orientalis black powder for blasting in dimensional stone quarries, sporting and fireworks uses. (1
Anti-Sickling Powder for Blasting and Fireworks Purposes: Study evaluated the effect of anthocyanins extracts from T. orientalis on sickle cells. The anthocyanin extracts exhibited antisickling activity, possible through interference with intracellular polymerization of HbS or scavenging of free radicals preventing erythrocyte sickling or hemolysis. (1
Safety / Genotoxicity Testing: Study evaluated the safety of five plants widely distributed in Africa. Using bacterial reverse mutation, T. orientalis was one of four that showed negative results, suggesting potential safety of the plants for use as supplements in high doses. (1
Laxative Effect: Aqueous extract was shown to have a laxative effect, inducing stimulation of rabbit duodenum contractility. Also, an aqueous extract exerted cholinimimetic and anticholinesterase effects. (17)
Mosquito Larvicidal Potential: In a study of four plants for mosquito larvicidal potential against Culex quinquefasciatus, a crude extract of Trema orientalis showed an LC50 2.95%. (18)
Analgesic / Antidiarrheal: Study evaluated the potential analgesic and anti-diarrheal activity of methanol and aqueous extracts of leaves in experimental acetic acid induced writhing and castor oil induced diarrhea in mice. The aqueous extract showed significant (p<0.001) analgesic effect. In anti-diarrheal screening, both extracts increased latent period (p<0.025) and decreased the number of stools (p<0.025) comparable to standard loperamide. (
In Vitro Thrombolysis / Clot Lysis Effect: Study evaluated the clot lysis effect of crude extracts of five Bangladesh plants viz., Trema orientalis, B. monnieri, C. frutescens, B. oleracea and U. sinuata in an invitro thrombolytic model using streptokinase as positive control. Chloroform fractions showed the highest clot lysis activity with T. orientalis at 46.44 ± 2.44%, compared to streptokinase at 80.77 ±1.12%. (
Antioxidant / Phenol Content: In a study of Ivory Coast medicinal plants, Trema orientalis showed the highest total phenol content (240.73 ±47.31 mgGAE/g). The extract showed dose dependent DPPH radical scavenging activity. Phytochemical screening yielded steroids and polyterpenes, polyphenols, flavonoids, lucoanthocyanins, gallic, catechins, quinones, coumarins, cardiotonic glycoside, saponins.

Antibacterial / Leaves: Study evaluated methanol and aqueous extract of leaves for antioxidant and antibacterial activities. Results showed strong antioxidant activity by DPPH assay with methanol extract IC50 of 110.25 µg/mL. Both extracts showed antibacterial activity at low concentrations. (
Antitrypanosomal / Leaves: In an in vitro antitrypanosomal study of 36 plant extracts from 10 plant species, Trema orientalis was one of the species that showed remarkable antitrypanosomal activity with high selectivity for trypanosomes. (
