Dongoyaro — the West African neem tree whose leaves, bark, and twigs form one of the most complete natural pharmacopoeia available to African communities. Antimicrobial, anti-parasitic, and immune-modulating.
For West African diaspora, the dongoyaro tree is synonymous with medicine — it is the tree that stood in every compound, the tree that the grandmother sent children to when they were sick. In Nigerian-American households, dried neem leaf is often carried back from visits to Nigeria or ordered online when someone is sick and wants the 'home medicine.'
Neem leaf's azadirachtin and gedunin have documented antimalarial activity in multiple in vitro studies — they disrupt the Plasmodium falciparum life cycle. A 2007 Nigerian randomized trial showed neem leaf extract equivalent to chloroquine in reducing malaria parasite load. Nimbolide has shown selective toxicity to cancer cell lines (prostate, colon, pancreatic) in multiple studies — one of the most studied natural anticancer compounds from Africa. The chewing stick tradition (neem twig as toothbrush) has been validated by oral health research: neem twigs inhibit Streptococcus mutans (primary cavity-causing bacteria) and reduce plaque formation. Blood glucose reduction in T2D animal models is well-documented.
Medicinal leaf tea: simmer 10-15 fresh or dried leaves in 2 cups water 10 min; strain; drink 1 cup. Very bitter — add honey for palatability. Topical use: fresh leaf paste applied to skin infections. Chewing stick: fresh young twig chewed at the end until frayed; use as toothbrush. Available at West African grocery stores and online as dried leaves, powder, or capsules.
