Palo Santo / Bursera graveolens
Palo Santo, meaning “holy wood” in Spanish, is the fragrant wood of Bursera graveolens, a tree in the same botanical family as frankincense and myrrh. When burned, the wood releases a distinctive sweet, woody and citrus-like aroma that has made it a valued incense throughout parts of South America.
The wood also has a history of use in traditional herbal practices, perfumery and essential-oil production.
Botanical Snapshot
Common Name: Palo Santo, Holy Wood
Botanical Name: Bursera graveolens
Plant Family: Burseraceae
Plant Type: Deciduous shrub or tree
Native Range: Mexico and Central America through northwestern South America and Peru
Part Commonly Used: Aromatic wood
Herbal Use & Bioactive Compounds
Palo Santo has been used in regional traditional medicine for a variety of purposes, including preparations associated with pain, arthritis and respiratory or nervous-system complaints. Modern research into these uses remains limited, and much of the available evidence is laboratory or preclinical rather than established clinical evidence.
The aromatic wood contains a complex mixture of terpenes and other volatile compounds. Essential-oil analyses commonly identify limonene as a major constituent, along with compounds such as alpha-terpineol, menthofuran, carvone and caryophyllene. The exact chemical profile varies with the plant material and geographic source.
Culinary Use & Common Forms
Palo Santo is not generally used as a culinary botanical.
It is most commonly available as wood sticks, chips, shavings, powdered wood, prepared incense and essential oil. Traditional wood incense is lit briefly and then allowed to smolder, releasing its aromatic smoke.
Palo Santo essential oil is a concentrated preparation and should not be treated as interchangeable with burning the whole wood.
Safety & Considerations
Burning Palo Santo produces smoke and airborne particles, so it should be used with adequate ventilation, particularly around people with asthma or other respiratory sensitivities.
Essential oil and other concentrated preparations may irritate the skin or sensitive tissues and should be used according to appropriate dilution and product directions. Incense-grade wood should not be assumed to be suitable for internal use.
As with any burning material, Palo Santo should be placed in an appropriate heat-resistant holder and kept away from flammable materials, children and pets.
Sourcing & Sustainability
Accurate identification and responsible sourcing are especially important with Palo Santo. Bursera graveolens is currently classified globally as Least Concern, but individual dry-forest habitats and local populations may still face pressures from habitat loss and harvesting.
In Peru, regulated management of Bursera graveolens includes the use of dead, dry and naturally fallen trees, and current forestry programs are working with local communities to strengthen sustainable harvesting practices. Choosing wood with a clearly identified origin and responsible harvesting information helps support both the dry forest and the communities that manage it.
The name “Palo Santo” is also applied to other plants, including a different South American tree historically known as Bulnesia sarmientoi. It should not be confused with Bursera graveolens when purchasing incense or essential oil.
Spiritual, Magical & Folk Traditions
Palo Santo has longstanding associations with cleansing, protection, healing, prayer and clearing unwanted influences. Its fragrant smoke is traditionally used in parts of South America to cleanse people and spaces and in practices surrounding mal aire, susto and other culturally specific concepts of spiritual or emotional imbalance.
In contemporary spiritual and metaphysical practice, Palo Santo is commonly burned for cleansing, meditation, grounding and preparing a space for ritual or intention-setting.
Cultural & Indigenous Uses
Ethnobotanical research in southern Ecuador documents Bursera graveolens wood being sold in traditional markets for use in baths and incense. Research among Saraguro yachakkuna also records Palo Santo as one of the plants incorporated into traditional preparations and healing ceremonies associated with conditions such as mal aire and susto.
Traditional healers in northern Peru have likewise documented the use of Palo Santo wood and smoke in cleansing practices and preparations intended to dispel unwanted or negative influences. These regional traditions help explain the plant’s continuing association with spiritual cleansing and ceremonial smoke.
