Guaiacwood essential oil is extracted by steam distillation process from the broken wood and sawdust of the plants. Guaiacwood is an ornamental evergreen tree with pretty rich blue flowers and the trunk is greenish-brown in color. It is traditionally used for treating rheumatish and rheumatoid arthritis, gout and venereal disease. This semisolid oil is a sweetly smoky, earthy and mysterious base note. It has a touch of rose to the aroma, and years ago was used to adulterate Rose Otto.
Emotionally the oil is relaxing and calming, a wonderful destressor. The tree is called sacred by the natives of Paraguay, so the oil might also be a good addition to a sacred or meditative blend. Physically it is said to be anti-inflammatory. Some source
