Bursera graveolens, known in Spanish as palo santo ('sacred wood'), is a wild tree native to the Yucatán Peninsula and also found in Peru and Venezuela.

Bursera graveolens is found in the seasonally dry tropical forests of Peru, Venezuela, Colombia, Ecuador, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, and El Salvador, and on the Galápagos Islands. The tree belongs to the same family (Burseraceae) as frankincense and myrrh. It is widely used in ritual purification and as folk medicine for stomach aches, as a sudorific, and as liniment for rheumatism. Aged heartwood is rich in terpenes such as limonene and α-terpineol.
