Available at West African grocery stores and markets in major US cities. Online from West African food suppliers. Growing awareness in the diaspora community.
Kolaviron is one of the most potent natural anti-inflammatory compounds documented in West African ethnopharmacology. Multiple Nigerian research studies show kolaviron inhibits COX-2 (same pathway as ibuprofen) at levels comparable to pharmaceutical anti-inflammatories. For asthma: a 2009 study found Garcinia kola extract significantly improved lung function parameters and reduced bronchospasm in asthmatic patients — mechanism: relaxes bronchial smooth muscle (similar to bronchodilator drugs). For osteoarthritis: a 2008 RCT in the Journal of Orthopaedic Surgery and Research found bitter kola extract significantly reduced knee osteoarthritis pain and improved joint function versus placebo. For diabetes: multiple animal studies and clinical observations document blood glucose-lowering activity — mechanism is likely alpha-glucosidase inhibition. The hepatoprotective effect of kolaviron protects against drug-induced liver toxicity in multiple studies — relevant for the high pharmaceutical burden in the APEX population.
Chew 1-2 seeds fresh (very bitter — the bitterness is the point). Traditional preparation: chew one seed slowly, swallow with water. Also available as a powder that can be added to tea. Seeds are shared at traditional ceremonies — eating them together is a ritual of community.
