The Office of the State Minister of Social Affairs supervises all activities in the field of social welfares. Houses for the aged, orphanages and schools for the handicapped are found all over the country, operated by either the government or by private institutions. Especially well-known is the Rehabilitation Centre for the physically handicapped in Solo, Central Java. Modern hospitals, community health centers have been set up. Through such efforts, modern medicine is gradually taking over from more traditional methods, although the practice of witchdoctors and the use of herbs for curing has not entirely disappeared, especially in isolated areas. Quite well-known are the herbal medicines of Java known as “jamu”, now becoming increasingly popular.
