Guaiacwood (Bulnesia sarmientoi)

Guaiacwood Essential Oil is obtained from the heartwood of Bulnesia sarmientoi, a plant in the Zygophyllaceae family. The plant is associated with the Gran Chaco region of South America, and the oil is valued for its smoky, balsamic, woody, slightly sweet, and faintly rosy with incense-like depth.

Traditionally, guaiacwood has been appreciated for its distinctive aromatic character. In modern aromatherapy, guaiacwood essential oil is used for blends where its specific scent profile can shape the mood of a formula rather than act as a generic fragrance.

This oil has a recognizable personality: smoked wood, balsam, incense, soft rosewood, leather, warm resin. That makes it useful for targeted blending when you want the exact character of guaiacwood, not just a broad essential oil note.

Bath

For bath use, always dilute first into a suitable dispersing base such as liquid soap, carrier oil, bath gel, or bath salts before adding to water. This helps distribute the oil more evenly throughout the bath and reduces the risk of irritation from undiluted essential oil contacting the skin directly.
