Frankincense, also known as olibanum, is made from the resin of the Boswellia tree. It typically grows in the dry, mountainous regions of India, Africa and the Middle East.
Frankincense has a woody, spicy smell and can be inhaled, absorbed through the skin, steeped into a tea or taken as a supplement.
Used in Ayurvedic medicine for hundreds of years, frankincense appears to offer certain health benefits, from improved arthritis and digestion to reduced asthma and better oral health. It may even help fight certain types of cancer.
