Amour Natural Frankincense (Boswellia carterii) 100% Pure Essential Oil Aroma Frankincense is a woody, spicy fragrance, with a hint of lemon. It is often described as having a ‘haunting’ aroma, perhaps partly referring to its historical significance during religious and spiritual ceremonies. Affects Frankincense is a calming oil, useful for people with anxious and obsessional dispositions. The oil is also renowned for rejuvenating mature skin properties, reputedly smoothing out wrinkles and helping with the appearance of age spots and crows feet. The oil is slightly astringent which is also good for balancing oily skin. This astringent nature of frankincense is also good for clearing mucus in the lungs and therefore is particularly useful for enhancing lung function.
