#SomPoi

Som poi, a spiny shrub known to Thai households for centuries, sits at the crossroads of tradition and science. Village life used its pods as a natural shampoo, while leaves and young pods steeped in decoctions were valued for relief from pain, fevers, and digestion issues. Today, researchers are uncovering the plant’s pharmacological potential, offering new health possibilities while honoring Thai heritage.

In many rural Thai homes, som poi remains a symbol of purification and renewal during Songkran and other New Year celebrations. Its use in scented water for ceremonial cleansing reflects a deep cultural belief in harmony with nature and fresh beginnings. Across generations, the plant has also served culinary and cosmetic roles, shaping household routines and local wellness practices.

For centuries, the spiny shrub known to Thais as “som poi” has quietly played a role in kitchens, bathing rooms, and healing traditions across the country. From using its pods as a cleansing shampoo to brewing its leaves for herbal teas, Acacia concinna—once a staple in village life—is now at the center of a scientific renaissance, as researchers unravel its ancient secrets and unlock new health possibilities for the modern age (prosea.prota4u.org; phar.ubu.ac.th).
