  1. aPersicaria hydropiper (L.) is synonymous with Polygonum hydropiper (L.). Persicaria hydropiper (L.) and Persicaria odoratum (L.) are commonly used interchangeably in literature while they are two distinct species. Efforts were made to identify the species of laksa plants used in the study. The plant was probably Persicaria hydropiper (L.). A specimen of the plant has been deposited in the National University of Singapore Herbarium for future reference.
