Frankincense resin is a very old sap from the Boswellia tree. It is commonly used to purify a space by burning on charcoal. It can be paired with herbs, oils, or used by itself. Any new age metaphysical shop should have resin like this available. Create a sacred space for yourself by placing the resin over burning charcoal an wafting it around whatever item you are working with or room you are working in.
