Young Living’s frankincense resin is harvested from Boswellia carterii trees located in northern Africa, near the Arabian Peninsula. Resin is a sap-like substance produced by trees. It flows out of tiny holes in the bark and then hardens to form a barrier against pests. The process of creating these holes and harvesting the resin is called tree tapping. When done correctly, tapping causes no harm to the tree and is a sustainable method for extracting the resin used to obtain essential oils. Most natural resin is amber-colored, similar to honey, but its shade can vary from pale yellow to dark brown. After being harvested, the resin can be chopped or powdered and made into incense or steam distilled to extract essential oils.
