Incense is a mixture of bark, herbs, and resins. Bark from sandalwood and cinnamon
are commonly used in the mix. Some of the herbs in the mixture may include henna,
sage, and lemon grass. Other woods, roots, and dried flowers are also used. Resin
is dried tree sap. The two most famous resins are frankincense and myrrh. To gather
resin, the bark of a tree is cut. The sap is allowed to slowly drip out. As the sap
dries, it becomes hard and forms into “tears”. It takes three months for the sap
to dry completely. The tears are then scraped off and used as resin.
