Indigenous healing practices are extremely diverse throughout Asia but often follow certain patterns and are still prevalent today. Many traditional healing practices include shamanism and herbal medicines, and may have been passed down orally in small groups or even institutionalized and professionalized. In many developing countries the only health care available until a few decades ago were those based on traditional medicine and spiritual healing. Now governments must be careful to create health policies that strike a balance between modernity and tradition. Organizations, like the World Health Organization, try to create policies that respect tradition without trying to replace it with modern science, instead regulating it to ensure safety but keeping it accessible. India in particular tries to make traditional medicines safe but still available to as many people as possible, adapting tradition to match modernization while still considering the economic positions and culture of its citizens.
