Frankincense comes from species of the Boswellia tree in the Burseracaea family. There are over 30 different species, but only a few provide tears that are of good enough quality to be useful. These include Boswellia serrata, B. carteri, B. frereana, and B. sacra. Frankinsense tears can be used for incense, 
Other actions include anti-inflammatory, anti-fungal, astringent, antiseptic, expectorant, carminative, anti-depressant, analgesic, emmenagogue. Frankincense is particularly useful for helping with joint inflammation, repair of the skin, and bronchial issues.
