Frankincense essential oil is typically extracted from the resin of the Boswellia carterii or Boswellia sacra tree. Frankincense is the hardened gum-like material (resin) that comes from cuts made in the trunk of the Boswellia carteri tree. Also known as olibanum, frankincense essential oil has a sweet, woody scent and is sometimes used to relieve stress. The oil is amber or greeny yellow in colour with a warm, spicy, slightly peppery scent. Thousands of years ago, frankincense was used in rituals for purification and the exorcism of evil spirits. It is believed that frankincense has the same effect on our bodies and fear, resentment, worry and confusion — and minds, cleansing negative thoughts — replacing them with a feeling of well-being and tranquillity. Frankincense oil> name is based on the term “frankincense,” which means “high-quality incense” in French. This oil has been used from ancient times for its soothing and medicinal characteristics.
