Throughout West Africa and Asia, including South-East Asia, Japan, northern Australia, Micronesia and Polynesia. It has recently been recorded from Texas (United States).
In Peninsular Malaysia, a decoction of the leaves, or leaves of other Lindernia species, is given as a medicine after childbirth. In the Moluccas, it is applied to boils and itches, herpes-like sores, and to sores caused by forest ticks. In Indo-China, the plant is considered to have emetic and cathartic properties, and has given good results in treating bilious disorders, dysentery, amenorrhoea, and hepatitis. It is one of the commonest plants in Chinese pharmacies in Indonesia and Malaysia. In Brunei, the powdered herb mixed with rice water is drunk to relieve diarrhoea, vomiting and cholera.
