L. lavandulifolia is distributed from India, and the Mascarenes to China and southwards throughout Malesia, though rare in Borneo and Papua New Guinea.


In Malesia, L. lavandulifolia is said to be used to heal chronic leg sores, dermatosis, as an anthelminthic for roundworms, and for appeasing affections of the nerves. In Java, a poultice is especially applied in veterinary medicine in order to cleanse stinking wounds from fly larvae. In Java, it is also used as a vegetable, and as a fodder for cattle.
