Frankincense, also called olibanum (Arabic: luban) is an aromatic resin obtained from trees of the genus Boswellia, ours a high concentrated blend particularly from B. carterii. It has strong-smelling, antiseptic, expectorant, and decongestant properties. Frankincense resin (gum, not oil) is edible and often used as traditional medicine in many Asian countries to cure bronchial and urinary infections. In China it is used to relieve menstrual pain, gum, mouth, and throat complaints, and also as a rejuvenating medicine in India. Boswellia trees can grow environments so unforgiving such as growing out of solid rock.
