Morphological Description

Musanga cecropioides is a fast-growing, evergreen, dioecious tree in the Urticaceae family, reaching heights of 18–45 m with an umbrella-shaped crown:

·       Bole: Straight, cylindrical, 50–100 cm in diameter, pale whitish to yellow, rough with granular texture; supported by stilt roots 2–3 m tall (Burkill, 1985).

·       Leaves: Large, palmately compound, 30–60 cm across, with 7–11 leaflets, ovate, 10–20 cm long, glossy green (Berg & Hijman, 1989).

·       Inflorescence: Axillary, enclosed in wine-red stipular sheaths, unisexual, with small yellowish flowers (Burkill, 1985).

·       Fruit: Compound, fleshy, edible, orange when ripe, 2–3 cm wide, borne in clusters (Fern, 2024).

Distribution and Habitat

Musanga cecropioides is a pioneer species native to tropical Africa:

·       Range: Sierra Leone to Angola, east to Uganda and DR Congo; introduced in Madagascar (Berg & Hijman, 1989).

·       Habitat: Wet tropical rainforests, secondary forests, disturbed areas (e.g., old farms, fallows); thrives at 0–1,500 m elevation, rainfall 1,500–3,000 mm/year, well-drained soils (Fern, 2024).

Ethnopharmacology

Musanga cecropioides is widely used in African traditional medicine, with phytochemicals like saponins, flavonoids, and tannins (Adeneye et al., 2006),It is widely used in traditional African medicine for its diverse therapeutic properties. The bark, leaves, roots, and latex are employed to treat various ailments due to the plant’s anti-inflammatory, analgesic, antimicrobial, antioxidant, and antidiabetic properties. Traditional uses include the treatment of rheumatism, fevers, wounds, ulcers, toothaches, and respiratory conditions such as asthma and coughs. The stem bark and root decoctions are also used for malaria, gastrointestinal disorders, and as a liver tonic. Phytochemical analyses have revealed compounds such as flavonoids, alkaloids, saponins, and tannins, which are believed to underlie its medicinal effects. Though traditionally well-regarded, further pharmacological studies are necessary to scientifically validate its efficacy and determine safe dosages for therapeutic use.

·       Galactagogue: Bark sap with maize pap in Nigeria boosts lactation. Burkill (1985) notes its traditional use among Yoruba women.

·       Antibacterial/Antifungal: Root sap in Cameroon fights infections. Uwah et al. (2013) found sap extracts (MIC 25 µg/mL) active against Escherichia coli.

·       Hypotensive: Bark decoctions in Ghana lower blood pressure. Dongmo et al. (2002) showed leaf extract (35 mg/mL) reduced rat blood pressure by 20%.

·       Antidiabetic: Stem bark in Nigeria manages diabetes. Adeneye et al. (2007) reported 500 mg/kg extract lowered glucose in diabetic rats by 35%.

·       Anti-inflammatory/Analgesic: Leaves in Osun, Nigeria, treat rheumatism. Sowemimo et al. (2015) found 150 mg/kg leaf extract inhibited edema in rats by 71%.

⚠  Toxicity Profile: High doses of stem bark extract (>3,000 mg/kg) caused transient sedation and reduced locomotion in rats. Sap may irritate skin due to phenolic compounds. Avoid in pregnancy due to oxytocic effects (Adeneye et al., 2006; Ayinde et al., 2006).

Additional Uses

·       Timber: Lightweight wood (density 0.3 g/cm³) for rafts, toys, crates; hollowed boles for canoes (Fern, 2024).

·       Water Source: Stilt roots and stems yield potable water in dry seasons (Burkill, 1985).

·       Culinary: Wood ash as vegetable salt; fruit flesh edible but rarely consumed (Berg & Hijman, 1989).

·       Ecological: Pioneer species aiding forest regeneration; shade tree in coffee plantations (Fern, 2024).
