Morphological Description

A large evergreen tree reaching 25-30m height with milky latex in all parts:

·       Leaves: Pinnately lobed (30-50cm long), 10-20 lobes per leaf, glossy adaxial surface

·       Flowers: Monoecious; male inflorescences (15-30cm) with 2000+ flowers, female spikes (5-20cm)

·       Fruit: Syncarpium (10-30cm diameter), 1500-2000 fused flowers, 0.5-6kg weight

·       Bark: Gray-brown with lenticels, exfoliating in thin flakes (5-10mm thick)

Distribution and Habitat

Native to the Indo-Malayan Archipelago (5°N-10°S latitude), now pantropical:

·       Optimal Conditions: 1500-3000mm annual rainfall, temperatures 16-38°C, volcanic soils (pH 5.5-7.0)

·       Historical Spread: Captain Bligh's 1789 voyage introduced 677 plants to the Caribbean

·       Ecological Role: Supports 150+ arthropod species including pollinator Eupristina wasps

Medicinal Properties

·       Antimicrobial: Latex flavonoids (artocarpin) inhibit Staphylococcus aureus (MIC 62μg/ml)

·       Skin Treatment: The latex of the tree is used to treat skin infections and fungal diseases.

·       Antidiabetic: Leaf extract reduces blood glucose by 35% in alloxan-induced diabetic rats

·       Insect Repellent: The crushed leaves can be used as a mosquito repellent.

·       Reducing Inflammation: In some traditional medicine systems, various parts of the plant are used to reduce inflammation.

·       Treat Illnesses: The bark and leaves have been used to treat illnesses like diarrhea, stomachaches, and ear infections in some cultures.

 

⚠  Toxicity Profile

Raw fruit contains artocarpin (0.15% FW) causing nausea (ED₅₀ 850mg/kg in mice). Latex proteases induce contact dermatitis in 12% of handlers (Jones et al., 2018).

 Additional Information

·       Nutrition: 27% carbohydrates, 1.5% protein, 70kcal/100g (boiled); glycemic index 58

·       Timber: Density 560kg/m³, Janka hardness 950 lbf, resistant to marine borers

·       Industrial: Latex used as adhesive (shear strength 3.2MPa); starch for bioplastics
