Vietnamese Herb Name: Rau Dắng

Common Culinary Herb Name: No common culinary name has really been established.   We use Bitter Herb (Greens) from the literal translation of the Việt name.  Slender Carpetweed is occasionally used in scientific context of Glinus Oppitisifolus. Other references also identify this plant as Bacopa Monnieri (Scrophulariaceae family, Water Hyssop). Both botanical names above  fit the descriptions of the plant very well, so there is still uncertainty in it’s correct taxa. With some still limited resources, we will continue to research the true scientific identity of this plant. The above mentioned Bacopa Monieri is used commonly as an herbal pill, whose medicinal qualities have origins from Ayurvedic medicine. But our research shows that Glinus Oppositifolius  is also being used as a culinary herb with bitter tasting characteristics . So for now,  we identify the plant as that for the time being. If there is anyone out there with some more information to share regarding the scientific identity of this herb,  your input is appreciated.
