What are resin essential oils?
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, resin can be chopped or powdered and made into incense or it can be steam distilled to extract essential oils.
