The Phytochemical and Pharmacological Properties of Persicaria odorata: A Review

Abstract

World Health Organization (WHO) reported that 88% of its member or 61 countries acknowledge the use of traditional and complementary medicines. Persicaria odorata is being used as traditional herbs to treat fever, nausea and promoting hair growth. Besides, it is used as an anti-inflammatory agent in Vietnam to relieve swelling and treat wounds, sores, and ulcers. This review aims to evaluate the phytochemical and pharmacological status of P. odorata. P. odorata is a plant with a high content of phenols and flavonoids. Among the essential chemical constituents in the P. odorata are methyl gallate, (+)-catechin, eupatoriochromene, n-dodecanal, polygonumins A, α-humulene and anthraquinone. P. odorata also exerts many pharmacological effects such as antioxidant, anti-inflammatory, antibacterial and anticancer effects. The commonly used part of P. odorata for extraction are leaves followed by the aerial part, rhizomes and stems. Nevertheless, more studies are needed to identify the efficacy and toxicity of P. odorata. New drugs could be developed from the active compounds of P. odorata in the future.

Anticancer Activities of Polygonum odoratum Lour.: A Systematic Review

“…Therefore, the phytochemical components of each extract might differ. In 2021, Azmi et al reported that different phytochemical constituents were present in various parts of P. odoratum ( Azmi et al, 2021 ). Moreover, the different extraction methods used by the studies produced diverse chemical profiles ( Chansiw et al, 2019 ; Nguyen et al, 2020 ).…”
