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.
There is no "official" English name for it, but it is sometimes called wild betel. It is known as chaphlu (ชะพลู, pronounced [t͡ɕʰá.pʰlūː]) or cha phlu (ช้าพลู, pronounced [t͡ɕʰáː pʰlūː]) in Thai; phak i leut or pak eelerd (ຜັກອີ່ເລີດ) in Lao; and pokok kadok in Malay. In Vietnam, the local name of Piper lolot – lá lốt – is applied to P. sarmentosum also.
P. sarmentosum is found from the tropical areas of Southeast Asia, Northeast India and South China, and as far as the Andaman Islands.
P. sarmentosum leaves are sold in bunches and are usually eaten raw.
