Bitter Orange Essential Oil
Citrus aurantium

Description
As the name implies, Bitter Orange Essential Oil possesses a bitter orange aroma reminiscent of a cross between the sweetness of Sweet Orange Essential Oil and the slight bitterness of Grapefruit Essential Oil. Although it's favored by some individuals, I have less experience in use of this particular oil. I personally tend to lean towards using sweet orange, grapefruit and the other citrus oils.
Bitter Orange Essential Oil is phototoxic. Refer to the safety information mentioned below.

Bitter Orange Essential Oil Safety Information
Bitter Orange Essential Oil is phototoxic. Tisserand and Young recommend a dermal maximum of 1.25% to avoid risk of phototoxic reaction. Avoid using Bitter Orange Oil that has oxidized due to a greater risk of skin sensitization. Reading Tisserand and Young's full profile is recommended.
