There are approximately 400 distinct ethnic groups in Indonesia (ethnic and sub-ethnic). Traditional medical practices are one example of the kinds of knowledge that have been handed down from one generation to the next in every nation, tribe, and subgroup within those nations. The people who live in the Lumajang Regency continue to have faith in the efficacy of traditional medicine. The practice of traditional medicine or shamans who treat residents around their residences in a number of districts in Lumajang, one of which is the Sumbersuko district, is evidence that this is the case. In the Sumbersuko District, there are a total of eight speakers who continue to uphold traditions related to the use of natural materials in medical practice. Interviews and questionnaires are being used as tools for the descriptive methodology that underpins this research project.
