Molave is a tree that reaches a height of 8 to 15 meters, smooth or nearly so, with inflorescences that may be slightly hairy. Leaflets are three, stalked, ovate to lanceolate, 7 to 18 centimeters long, pointed at the tip, shining and quite smooth. Flowers are blue, numerous, 6 to 8 millimeters long, hairy outside the corolla, borne on terminal, paniculate and ample inflorescences, up to 20 centimeters in length. Fruit is rounded, 5 to 6 millimeters in diameter.

33.18 ±0.49 % crude fiber, 16.94 ±2.69 % crude protein, and 21.76 ± 2.60 % carbohydrates. (14)
- Study of chloroform extract of dried leaves yielded a flavone, retusin. (see study below)
- Wood takes on a yellowish-green or greenish brown tint when boiled in water
Antimicrobial and antifungal properties have been reported.
- Considered carminative, anthelmintic, digestive.
- Studies have suggested antioxidant, larvicidal, antibacterial, wound healing, anti-inflammatory, anti-ulcer, antispasmodic, wound healing properties.
Bark, leaves, stems, wood.
- Decoction or infusion of wood considered a remedy for poisons, as it induces vomiting.
- Decoction of bark used for diarrhea.
- Ayta people of Porac, Pampanga burn dried leaves and stems as repellent against hematophagous insects. (15) Aytas use the peels, stems, and leaves for preparing baths during and after pregnancy. (18)
- In Southeast Asia, used for stomatitis, anorexia, blindness, leprosy, worm infestation, rheumatic swellings.
- In Kerala State of India, bark and wood decoction of Terminalia catappa and V altissima used for bathing women after childbirth.
- Bark and wood used as styptic, emetic, antitoxic, and to treat jaundice and dropsy. (10)
- Wood: Known in the Philippines for its extremely hard wood with a density of 940 kg/m3 at 15% moisture, resistant to fungal, termite, and Lyctus beetle attack, but not to marine borers. Used like teak for shipbuilding and construction in contact with the ground. Also a source of firewood.
- Fish poison: Fruit and bark used as fish poison in the Philippines.
- Fodder: Leaves used as fodder.
- Resin: Exudes a yellow resin when the wood is treated with lime. (10)
- Tannin / Dyestuff: Shavings soaked in water yields a yellow extract.
• Iridoid Glucosides / Antioxidant: Study yielded six new iridoid glucosides together with two known iridoids, agnuside and negundoside, from the ethyl acetate extractive of the leaves of V altissima. Compounds 2 - 4 showed potent antioxidant activity by free radical scavenging and DPPH radical scavenging methods. (1)
• Larvicidal: Study of methanol extracts of four vitex species - V. negundo, V trifolia, V peduncularis and V altissima, showed varying levels of larvicidal activity. The early fourth instar larvae of Culex quinquefasciatus was used for the larvicidal assay. (2)
• Antibacterial / Leaf and Stem: Study of leaf extract showed moderate activity against both Gram-negative and Gram-positive bacteria. (3) Study investigated the antibacterial activities of crude methanolic extracts of Vitex parviflora leaves and stem and Cyanthillium cinereum against human pathogens. Leaf and stem extracts of V. parviflora exhibited high antibacterial activity against Staphylococcus aureus. Increasing concentration of VP leaves showed increase anti-Staphylococcal activity as evidenced by increased diameters of zone of inhibition. (16)
• Wound Healing: Study was done on the wound healing property of ethanol leaf extracts of V. trifolia and V latissima. On comparison with control group. both leaf extracts were found to possess significant wound healing potency. (4)
• Anti-Inflammatory / Antioxidant / Phytochemicals: Study of ethyl acetate extracts of leaves of VA yielded a new tetrahydrofuranoid lignan, altissinone and a new acylated flavone C-glucoside. The extract exhibited significant anti-inflammatory activity in the rat paw edema model. The flavonoids and triterpene acids showed moderate antioxidant and 5-lipooxygenase inhibitory activities. (5)
• Anti-Inflammatory: Study of different leaf extracts of V. altissima was done on male albino rats to evaluate acute and subacute anti-inflammatory activity. Results showed significant anti-inflammatory activity with aqueous and alcoholic extracts and supports the tribal use of the plant for ailments of short duration. (6)
• Antimutagenic / Terpenes and Sterols: Study of ethyl acetate extract of leaves indicated the presence of phytol 1a, with lupeol 1b and ß-amyrin 1c as impurities, and sitosterol and stigmasterol. Micronucleus tests indicated reductions in the number of micronucleated polychromatic erythrocytes induced by Mitomycin C, indicating antimutagenic activity. (7)
• Antiulcer Healing: Study evaluated the extracts of three plants (bataw, molave, and alugbati) on albino mice with ethanol-induced ulcer. Results showed molave and alugbati with greater anti-ulcer activities than bataw. (News: Phil Star) (8)
• Antispasmodic / Bark: Study evaluated a crude bark extract for antidiarrheal effect of V. parviflora as alternative remedy for diarrhea in albino mice. (11)
• Antioxidant Potential / Total Phenolic and Flavonoid Content / Leaves: Study of air-dried leaves yielded a total phenolic content of 356 ± 19.4 mg gallic acid equivalent (GAE) per 100g air-dried leaves and total flavonoid content of 321.16 ± 16.71 mg quercetin equivalent (QE) per 100g air-dried leaves. Results suggest high antioxidant potential of extractable components from the leaves of molave. (see constituents above) (14)
• Flavone / Retusin / Antimicrobial / Dried Leaves: Study of chloroform extract of dried leaves yielded retusin. Antimicrobial testing of retusin indicated moderate activity against fungi, A. niger and low activity against bacteria, P. aeruginosa. It was inactive against fungi C. albicans and T. mentagrophytes and bacteria E. coli, S. aureus, and B. subtilis. (17)
