Warburgia stuhlmannii

Warburgia stuhlmannii is used in several East African traditions as a bitter-tasting, warming remedy for fever and respiratory complaints. In the coastal woodlands of Kenya and Tanzania, people steep or decoct inner bark in water to drink as a febrifuge and to treat coughs and malaria, according to the Kenya Forestry Research Institute’s Ethnobotanical Database and “Medicinal Plants of East Africa.” Inland in coastal Tanzania’s Lindi region, healers prepare a bark decoction for fever and malaria, and also make a poultice by crushing bark with water to apply to skin sores and wounds, as documented by the Uppsala PROTA database. Among communities near the Usambara Mountains of northeastern Tanzania, infusions or decoctions of leaf are taken for colds and chest complaints, while some practitioners macerate bark in alcohol or water to use as a general tonic, noted by Schmelzer and Gurib-Fakim in their African ethnobotanical overview.

A common preparation for a fever or cough remedy is a bark decoction. Roughly 10–20 g of chopped inner bark are simmered in 1 L of water for 20–30 minutes, then strained. The resulting liquid is taken warm, one cup (about 150–250 mL) two or three times daily as needed. A simple 1:5 (weight/volume) tincture can also be prepared by macerating 50 g of dried bark in 250 mL of 50% ethanol for two weeks in a dark place, shaking daily; 1–2 mL can be taken in water once or twice daily. Because Warburgia stuhlmannii contains potent sesquiterpenoids and the safety profile is not fully established, it is best avoided during pregnancy and breastfeeding; children should receive lower doses under practitioner guidance, and people with known liver disease should consult a professional.

Active constituents that support the plant’s traditional uses are sesquiterpenoids characteristic of the Canellaceae, including warburginal, polygodial, muzigadial, and 3β-acetoxyazadirone; these drimane-type compounds are bitter and irritant to mucous membranes and have documented antimicrobial, anti-inflammatory, and analgesic effects, providing plausible explanations for its fever-lowering, cough-relieving, and wound-healing applications, as reported by Campbell et al., 1992, and later confirmed by insect and plant chemistry studies of the genus.

Today, W. stuhlmannii remains in demand in coastal East African communities, with parts collected for local teas, decoctions, and tinctures and cited in regional pharmacopoeias and ethnobotanical records, while continued pharmacological research explores its sesquiterpenoids for anti-infective and anti-inflammatory potential.
