桔橙精油的與眾不同


撰文╱米恩・羅德里奎茲醫學博士

桔橙是柑橘(mandarin orange)和甜橙(sweet orange)的混種,是一種獨特而歷史短暫的柑橘樹。儘管類似的物種在中國已經生長了多個世紀,但普遍相信第一棵桔橙樹自然生長在19世紀晚期的阿爾及利亞花園中,後來被引入加州,在那裡培育了幾種不同的品種。至今,桔橙可在全世界生長,並以甜美的味道和從果皮萃取出來的精油為人所知。

是什麼使桔橙與眾不同?

桔橙在柑橘類植物中非常獨特,比其他柑橘樹更能適應溫度變化,具體來說,不需要炎熱的溫度。像北非、地中海和加州等平均氣溫較高的地區能生產最珍貴的桔橙(以大小和數量而論),但整體來說中國是產量最大的產區。隨著得天獨厚的生長環境,果皮內含的芳香化合物具有和野橘類似的香氣,並帶有淡淡的檸檬味。

要如何使用桔橙精油?

桔橙精油的主要成分是檸檬烯,已具有許多研究證實其效益。
