Seville or sour orange as it is called in Jamaica has medicinally uses. The dried outer peel of the fruit of bitter orange, with the white pulp layer removed, is used medicinally. The leaves are also commonly used in many folk traditions. The bitter orange tree is indigenous to eastern Africa, Arabia, and Syria, and cultivated in Spain, Italy, and North America.

There is a rare type of Seville's oranges in Jamaican that does not have thick dimpled skin, in fact, you won't know the difference between it and sweet oranges just by looking at it.
Bitter orange is used similarly in a wide variety of traditions. In Mexico and South America the leaf is used as a tonic, as a laxative, as a sedative for insomnia, and to calm frazzled nerves.
The peel of the fruit is used for stomach aches and high blood pressure. 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 odour and flavour, 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.

Bitter orange oil may possibly cause light sensitivity (photosensitivity), especially in fair-skinned individuals. Generally this occurs only if the oil is applied directly to the skin and then exposed to bright light; in rare cases it has also been known to occur in people who have taken bitter orange internally. The oil should not be applied topically and anyone who uses it internally should avoid bright light, including tanning booths.
