Bursera graveolens, known in Spanish as palo santo ("holy wood"), is a wild tree native from Mexico and the Yucatán Peninsula to Peru and Venezuela that inhabits the South American Gran Chaco region (northern Argentina, Paraguay, Bolivia and the Brazilian Mato Grosso). It is also found in Costa Rica, El Salvador, Guatemala, Honduras, Colombia, Ecuador, Peru and on the Galápagos Islands. The tree belongs to the same family (Burseraceae) as frankincense and myrrh. It is widely used in folk medicine for stomach ache, as sudorific, and as liniment for rheumatism. Aged heartwood is rich in terpenes such as limonene and α-terpineol.
Palo Santo is used for crafting objects and to produce burning sticks and incense. Production of essential oil is attracting most of the modern interest. Chemical composition, as reflected by aroma, is variable. The essential oil of Palosanto is generally termed "Palo Santo Oil", and has received the Chemical Abstract Services number, 959130-05-3. When used as an ingredient in cosmetics the INCI name "Bursera graveolens wood oil" should be listed.
The use of Palo Santo from B. graveolens is traditional in South America, especially in Ecuador. According to the local customs, it is used against the "mala energía" (bad energy) ("Palo Santo para limpiar tu casa de la mala energia, Palo Santo para la buena suerte" or "Palo Santo to clean your house of bad energy, Palo Santo for good luck"), which may sometimes refer to clinical disease. Its use reportedly dates back to the Inca era. Palo Santo is common today as a type of incense.
