I first picked up a bottle of Organic Essential Oil of Litsea Cubeba (May Chang) 25 years ago when its piercing sherberty aroma blew my mind. I combined it with Organic Essential Oil of Bourbon Geranium in what has become our best selling Aromasoar Solid Organic Perfume. I personally prefer Litsea Cubeba which derives from the Laurel family to Lemon for instance which is awfully musky and oftentimes too sweet in a perfume. Litsea has the added advantage of not 'turning' like citrus oils. The perfumes were devised to lift one's mood whilst travelling. And as they're non liquid they slip through security with no problems at all. I love to use this aroma combo to re energise on a long journey. I'm 3 hours to Glasgow airport in the morning before I even jump on the 'red eye' and I can tell you this one works its magic every time!
