Long Pepper Alkaloids Curbed Weight Gain in Mice

Thai Long Pepper · ดีปลี · Piper retrofractum

Thai Long Pepper — ดีปลี (dee-plee) — Piper retrofractum.

It dries into a knobbly little spike, hard as a twig, and one bite runs hotter and sweeter than a black peppercorn, with a slow warmth that climbs the back of the throat. Cooks pound it fresh into nam prik and grind it into northern larb spice blends. Piperine gives it that heat; in high-fat-diet mice, alkaloids from the fruit curbed weight gain and blood fats. How to use Thai long pepper: the dried fruiting spike, a pinch at a time.

Long pepper is an old Thai spice making a comeback — a knobbly dried spike, hotter and sweeter than a peppercorn, ground into curry pastes and warming tonics. Isolated piperine can alter some medication levels, but that has not been shown for ordinary culinary doses of this whole fruit; ask your doctor before using concentrated products with prescriptions. Give the vine a trellis and it grows easily from cuttings when the rains come.
