According to locals, this wild herb is present throughout Vietnam. The majority of Vietnamese people use them in salads. When dunked in a Vietnamese dipping sauce, this salad, known as gi rau càng cua in Vietnamese, tastes incredible. The herb crab claw is nourishing, cooling, and antipyretic. It is also effective in treating some skin conditions. When I inquired on the preparation of the crab claw herb, one vendor said, "Beef salad with oil vinegar sauce." There are numerous more methods to prepare this dish, she added. I suppose there are countless possibilities, just like with many other Vietnamese plants.
