A curandero is a traditional native healer or shaman found primarily in Latin America and also in the United States. A curandero is a specialist in traditional medicine whose practice can either contrast with or supplement that of a practitioner of Western medicine. A curandero is claimed to administer shamanistic and spiritistic remedies for mental, emotional, physical and spiritual illnesses. Some curanderos, such as Don Pedrito, the Healer of Los Olmos, make use of simple herbs, waters, or mud to allegedly effect their cures. Others add Catholic elements, such as holy water and pictures of saints; San Martin de Porres for example is heavily employed within Peruvian curanderismo. The use of Catholic prayers and other borrowings and lendings is often found alongside native religious elements. Many curanderos emphasize their native spirituality in healing while being practicing Catholics. Still others, such as Maria Sabina, employ hallucinogenic media. Most of the concepts related to curanderismo are Spanish words, often with medieval, vernacular definitions.

Shamanism or samanism is a religious practice that involves a practitioner interacting with the spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination, or to aid human beings in some other way.
