《纲目拾遗》：“《纲目》水藻集解下有马藻，叶亦对生，形亦微似，而实非一物。盖藻可食，此则不可食。故主治亦别也。俗呼边箕萍。《群芳谱》麻藻萍之异种，长可指许。叶相对联缀，不似萍之点点清轻也。按麻薸即今蜈蚣萍。”临床应用 相关配伍
"Compendium of Materia Medica: In the section on aquatic plants in the Compendium, there is a mention of horseweed, which has leaves that grow opposite each other and a shape that is somewhat similar, but in reality they are not the same. While horseweed can be eaten, this plant cannot. Therefore, their main medicinal uses are also different. Commonly known as 'Bianji Ping'. In the 'Compendium of Materia Medica', it is mentioned that hempweed and duckweed are different species, with a length that can be measured by a finger. Their leaves are arranged opposite each other, unlike the scattered and light appearance of duckweed. According to 'Compendium of Materia Medica', hempweed is what is now known as Centella asiatica. Clinical applications and relevant combinations."
