Benito Ruiz Alvarez, a traditional doctor, or “i´lol” in the Tsotstil language, performs a healing for Josefa López Santis in San Cristóbal de las Casas, a city in Mexico’s Chiapas state. Ruiz Alvarez uses prayers, plants, candles, stones, incense and a traditional drink called posh as part of the ceremony. The facility is owned by the Organización de Médicos Indígenas del Estado de Chiapas, an organization of doctors and midwives with Tsotsil ancestry who preserve medicinal traditions, including midwifery, botany and bone setting.
