Bitter orange Citrus aurantium and its active constituent, synephrine, are sometimes included in weight-loss formulas. Synephrine has been found to activate a type of nerve receptor that helps regulate carbohydrate and fat metabolism. Studies in healthy adults have noted single doses of bitter orange extract increased fat-burning during exercise in men and women, and energy used during digestion, a major avenue for expending calories, in women, but not men.

Synephrine is a weak stimulant, and is often combined with stronger central nervous system stimulants, particularly caffeine, which may increase calorie-burning.

Bitter orange has a complex chemical makeup, though it is perhaps most known for the volatile oil in the peel. The familiar oily residue that appears after peeling citrus fruit, including bitter orange, is this volatile oil. It gives bitter orange its strong odor and flavor, and accounts for many of its medicinal effects.

Besides the volatile oil, the peel contains flavones, the alkaloids synephrine, octopamine, and N-methyltyramine, and carotenoids.

Usually 1 to 2 grams of dried peel is simmered for 10 to 15 minutes in a cup of water; three cups are drunk daily. As a tincture, 2 to 3 ml with a weight-to-volume ratio ranging from to is often recommended for use three times per day. Decoctions of bitter orange substantially increased blood levels of cyclosporine in pigs, causing toxicity.

Bitter orange might, therefore, interact with drugs that are metabolized by CYP3A. To be on the safe side, bitter orange should not be combined with prescription medications, unless someone is under the care of an experienced natural medicine clinician.

Bitter orange oil may possibly cause light sensitivity photosensitivity , especially in fair-skinned individuals. The oil should not be applied topically and anyone who uses it internally should avoid bright light, including tanning booths.
