Enhalus acoroides (L.f.) Royle is a seagrass, in a monotypic genus of marine flowering plants belonging to the family of Hydrocharitaceae. E. acoroides is wide spread in the Indian to Pacific Oceans. 1 There are approximately 50 species of seagrasses in 12 genera around the world and E. acoroides is common in the major seagrass areas of Southeast Asia. 2 In Thailand, it is one of twelve seagrass species are found in 19 provinces. 3 It occurs in brackish water canals down to the lower intertidal and subtidal zones on mud, muddy sand and sandy coral substrates. In the gulf of Thailand, it grows on coarse substrate ranging from medium and coarse sand to coral rubble at a depth of 0.5-1.0 m. 4 Many studies have shown the benefits of E. acoroides. It has long been recognized as critical coastal nursery habitat for estuarine fisheries and wildlife. It functions as direct food sources for fish, waterfowl, dugongs, manatees and sea turtles. It also participants in nutrient cycling processes and acts as a stabilizing agent in coastal sedimentation and erosion processes. 5-7 The seeds of E. acoroides have been traditionally eaten in the Philippines. The raw seeds are described as crunchy and sweet while boiled seeds contained more starch and taste like cooked sweet potato. 8 In folk medicine, it has been used for a variety of remedial purposes, e.g. for the treatment of fever and skin diseases, muscle pains, wounds, stomach problems, a remedy against stings of different kinds of rays and tranquillizers for babies.
