Today, various bitter orange peel extract products are promoted for heartburn, nasal congestion, weight loss, appetite stimulation or suppression, and athletic performance.

The bitter orange fruit extract contains p-synephrine and other naturally occurring chemicals. p-Synephrine is structurally similar to ephedrine, the main component in the herb ephedra, but p-synephrine has different pharmacologic properties (how the component acts). The U.S. Food and Drug Administration banned the use of ephedra in dietary supplements because it raises blood pressure and is linked to heart attack and stroke. Bitter orange is commonly used as a substitute for ephedra in dietary supplements.

Bitter Orange Extract Benefits:

1.Indigestion, Heartburn, and Low Stomach Acidity

Bitter orange extract has traditionally been used as a digestive aid.Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production. As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine, wormwood, gentian,dandelion, blessed thistle, yarrow, devil’s claw, bitter orange, bitter melon, juniper, andrographis, prickly ash, and centaury.. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.


Bitter orange fruit extract has a history of use as a calming agent and to counteract insomnia. There is no clinical trial data to support its efficacy in this regard. The usual amount of tincture used is 2 to 3 ml at bedtime.


Bitter orange peel extract contains synephrine, which might promote weight loss. Although historically used to stimulate appetite, bitter orange is frequently found in modern weight-loss formulas because synephrine is similar to the compound ephedrine, which is known to promote weight loss.
