The species is a folk medicinal herb in common use. Although it is widely distributed, the plant has been extensively collected outside Hong Kong for medicinal uses, causing the decline in the population size and number of individuals. In Hong Kong, the species is widely distributed and is not under any particular threat. This species is also protected by the Animals and Plants (Protection of Endangered Species) Ordinance (Cap.187).
