 "The herb has a coriander-like smell with a clear lemony note. Pungency, which dominates in the closely related water pepper, is hardly present." [[http://gernot-katzers-spice-pages.com/engl/Pers_odo.html]]
-"Polygonum odoratum Lour. has been reclassified as Persicaria odorata (Lour.) Soják [Wilson, K. L. Polygonum sensu lato (Polygonaceae) in Australia. Telopea 1988, 3, 177−182]; other synonyms currently used are Vietnamese mint or Vietnamese coriander and, in Malaysia, Daun Laksa or Laksa plant. The aerial parts of Laksa plant are highly aromatic, and they contain many organic compounds such as (Z)-3-hexenal, (Z)-3-hexenol, decanal, undecanal, and dodecanal that are typical for green, citrus, orange peel, and coriander odors. In addition to these aldehydes, 3-sulfanyl-hexanal and 3-sulfanyl-hexan-1-ol were discovered for the first time in this herb. The fresh leaves are pungent when they are chewed, although the active compound has never been identified. The pungency of Persicaria hydropiper (L.) Spach (formerly Polygonum hydropiper L., synonym water pepper) is produced by [[https://en.wikipedia.org/wiki/Polygodial|polygodial]], a 1,4-dialdehyde derived from drimane terpenoids. We also identified polygodial as the active pungent compound in P. odorata (Lour.) Soják." \\
+The steam-distilled essential oil (0.52% yield) from the leaves and stems of Polygonum odoratum Lour. contained dodecanal (44.0%), decanal (27.7%), and decanol (10.8%) as main constituents. \\
