Frankincense is known as the king of all oils and has been used since ancient days. Its health benefits are numerous. It is one of my favorite anti-anxiety oils to use during my work shift as a labor and delivery nurse when moms are anxious. Meditation and emotional balance make this a great oil to diffuse during stressful times or depressing times, or simply during your yoga or stretch routine. Many have found skin benefits from wound healing, wrinkles, stretch marks, and warts.
