Description

Persicaria minor is native to South East Asia, including Malaysia, Thailand, Vietnam and Indonesia.[3] It grows wild in cooler highlands, but is also found in wet lowland areas near rivers, ditches, and canals. It is a creeping plant with slender stems, and grows upright to a height of 1 to 1.5 meters. The creeping stem is green with reddish tinge, is cylindrical in shape, and has short nodes about 9 mm apart. Its leaves are long and narrowly-tapering, alternately arranged, and green with short, reddish petioles. Its flowers are minute, pale violet, and are 12 to 15 cm long.[4]

Uses

Persicaria minor is an edible herb. In Malaysia and Singapore, the shoots and young leaves are eaten raw as part of salad (ulam); used as an aroma spice additive in peppery dishes such as laksa, nasi kerabu, asam pedas and tom yam; used as tea leaves; and used for topical applications.[5] Its oil has been used for aromatherapy and in treatments for dandruff.

In Malaysian traditional medicine, P. minor has been used in post-natal tonics and for treatment of digestion.[4]

Pharmacological studies on P. minor have indicated anti-oxidant, LDL oxidation, anti-inflammatory and anti-microbial activities,[6] digestive enhancing and anti-ulcer activities,[7] as well as cognitive enhancing activities.[8] Comparative studies have been carried out to analyse the metabolites not only in the plant's leaves, but also in its stem and roots.[9]
