A fermented or brewed drink made from mauby bark (Colubrina elliptica), boiled with spices (cinnamon, cloves, anise, orange peel) and sweetened slightly — intensely bitter, slightly fizzy when fermented, the Caribbean's traditional metabolic health tonic.
Mauby is the Caribbean's grandmother medicine — the thing grandmothers made when blood pressure went up and no doctor was accessible or affordable. In the Eastern Caribbean diaspora, the search for mauby bark is the first thing people do when they arrive in a new city. It represents the intersection of Caribbean folk medicine and the legacy of African bark-medicine traditions.
Mauby bark's hypocholesterolemic effects have been demonstrated in multiple Caribbean ethnopharmacology studies. A 2015 study in the West Indian Medical Journal found mauby bark extract reduced total cholesterol by 17.6% and LDL by 22% in hyperlipidemic rat models. The bitter compounds (gentian-class iridoids) stimulate bile acid production and secretion — a mechanism that directly removes cholesterol from circulation. The triterpenoid saponins in Colubrina elliptica are structurally similar to cholesterol-lowering compounds found in red yeast rice and berberine-class plants. The ACE-inhibiting quercetin provides the blood pressure reduction pathway.
Method 1 (brewed): Boil mauby bark pieces (available at Caribbean grocery stores) with cinnamon sticks, cloves, anise stars, orange peel for 20-30 minutes until very dark and intensely fragrant. Strain. Sweeten lightly with raw cane sugar or date syrup. Chill thoroughly. Method 2 (fermented): cool the brewed tea, add a small amount of mauby from a previous batch as starter, allow to ferment at room temperature 1-3 days until slightly fizzy.
