Frankincense is one of more than 90 types of essential oils that are popularly used in the realm of aromatherapy. Essential oils are made from petals, roots, peels, and bark of flowers, herbs, and trees. They get their name because they give the plant its “essence,” or fragrance. They can be inhaled or diluted (watered down) and applied to your skin.
Each essential oil has its own unique smell and potential health benefits. Some popular ones include rose, lavender, sandalwood, chamomile, jasmine, and peppermint.
Frankincense is not one of the most widely used oils, but it does have potential health benefits. You may also find it as a resin or extract. It's sometimes sold as a dietary supplement or as an ingredient in skin care or other products.
