#KnemaAngustifolia

For generations, the robust trees of Knema angustifolia—known in Thai as กำลังเลือดม้า (gamlang lueat ma) or sometimes as ประดงเลือด, and in English by its scientific name—have quietly offered their bark to folk healers across Thailand’s countryside. Local herbalists, passed down wisdom through word of mouth, have prized its blood-red sap for its reputed power to invigorate blood, fortify the body in times of weakness, and ease various ailments. Today, as the world looks anew at traditional remedies, a new chapter is being written for this storied botanical, reaching from Lanna village clinics to the cutting-edge labs of modern phytochemistry and pharmacology.
