Damascus Rose in an incense resin that was developed by an incense company for the church by clergy looking for something that smelled a little different than traditional incense. It is an imitation of a hybrid of Iranian Rose, Bulgarian Rose, Turkish Rose, Raif Rose, Arab Rose a, Ispaphan Rose and Castile Rose. Very sweet smelling and mostly (never say never) hypoallergenic. Unlike pur sap resins, it burns cleaner and doesn't load up the charcoal as much. Very fragrant and indoor friendly.
