How It Works

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.8, 9

How to Use It

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 1:1 to 1:5) is often recommended for use three times per day. 10 The purified volatile oil is generally avoided for reasons discussed in the side effects section.
