Queen of Heaven (Lotus flower - "Fit for a Queen") is 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 very aromatic, floral, and sweet smelling and mostly (never say never) hypoallergenic. Used for purification, prosperity, and mental clarity. Unlike pure sap resins, it burns cleaner and doesn't load up the charcoal as much. Very fragrant and indoor friendly.
