Synonyms

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[1] 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[2] 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.[1] Aged heartwood is rich in terpenes such as limonene and α-terpineol.

Uses

Modern uses

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.

Ethnobotanical uses

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.[3] Palo Santo is common today as a type of incense.

Palo Santo oil was used during the time of the Incas for its reputed spiritual purifying properties. Today, palo santo oil may be applied to the body (such as at the base of the skull or on the spine) to increase relaxation,[3] similar to aromatherapy.

Palo santo may be burned, similar to incense, by lighting shavings of palo santo wood. In Peru, a shaman, or medicine man, reportedly lights palo santo sticks and the rising smoke will enter the "energy field" of ritual participants to "clear misfortune, negative thoughtprints, and 'evil spirits'".[4] Peruvians harvest fallen branches and twigs of the B. graveolens tree, a practice that is regulated by the government of Peru, so trees are not cut for wood harvesting.[5] The charcoal of palo santo sticks can also be used for ritual smudging.

Palo santo wood has also been used in indigenous medicine in South America. In northwest Argentina, the Criollo people burned the wood of palo santo together with the leaves of Ruta chalepensis. The resulting smoke was blown into the ears of patients with otitis. Another medicinal smoke was created by burning palo santo along with yerba mate and feathers of the rhea bird; inhaling this smoke every 9 days was reputed to treat "aire",[6] an illness recognized in many Latin American cultures and believed to be caused by rapid changes in weather temperature.[7]
