Piper sarmentosum is a plant in the Piperaceae family used in many Southeast Asian cuisines. The leaves are often confused with betel, but they lack the intense taste of the betel leaves and are significantly smaller.
Leaves are sold in bunches and are usually eaten raw.
Leaves are also used in traditional Asian medicines. Chemical analysis has shown the leaves contain the antioxidant naringenin. Amides from P. sarmentosum fruit have been shown to have anti-tuberculosis and anti-plasmodial activities.
