Benzoin Incense Sticks

Benzoin is the sap (gum resin) that comes from cuts in the trunk of trees that belong to the Styrax family.
Benzoin is used on the skin for ulcers, bed sores (pressure ulcers), cracked skin, and many other conditions, but there is no good scientific evidence to support these uses.
Benzoin is used in small quantities in foods as a flavoring.
There is some evidence that benzoin might act as a skin protectant and may also help to break up chest congestion by thinning mucous and making it easier to cough up.
