Distribution: The sweet orange tree is hybrid between mandarin orange (C. reticulata) and pumello (C. grandis), originating in China. Today there are many varieties that are primarily cultivated for their fruit. Oranges are grown throughout the tropical and subtropical regions of the world. The major producers are Florida, California, the Mediterranean region and Brazil. With many of the Citrus species, three distinct essential oils can be extracted, each with somewhat different chemical constituents and medicinal properties. Essential oils extracted from the leaves and young twigs are usually marketed as petitgrain. Petitgrain is primarily extracted from the bitter orange tree (C. aurantium), but it is also extracted from sweet orange (C. x sinensis), lemon (Citrus limon), mandarin (C. reticulata) and bergamot (C. bergamia).

Extraction: Sweet orange essential oil is prepared by steam distillation of the leaves and young twigs.

Indications: Sweet orange essential oil reduces muscle spasms and tension. It helps to relax strained or sore muscles and reduce fatigue.

Contraindications: None when used topically.
