doTERRA sources its Guaiacwood essential oil sustainably and ethically from Paraguay. We are working side-by-side with our sourcing partner to change the future of the endangered forests in the Gran Chaco basin, one of the most biodiverse regions in the world. The essential oil is steam-distilled from the heartwood of the Bulnesia sarmientoi and mixed with Fractionated Coconut Oil to create doTERRA Guaiacwood essential oil. It has a distinctively earthy, grounding, slightly sweet aroma, and its woody scent creates a calming, peaceful atmosphere.
