Bay Laurel or Laurel Leaf essential oil is well-regarded in aromatherapy due to its unique molecular structure. It contains elements of nearly all of the primary chemical groups which make up essential oils. The result is a broad range of therapeutic uses.

Most outstanding is the mention it receives by Dr. Kurt Schnaubelt in 'Advanced Aromatherapy': "Its positive effects on the lymphatic system are undeniable. Rubbing a few drops of bay laurel on swollen lymph nodes will produce an immediately noticeable relieving effect. The positive and pleasant effect of this oil is so distinct and strong that one application will normally suffice to convince the most hardened skeptic to use it."

The oil has traditionally been used to alleviate digestive complaints, but its modern aromatherapy applications make use of its antiseptic, anti-microbial, expectorant, mucolytic, anti-bacterial and anti-infectious properties. It may be included in blends for breathing support, and the aroma may be more appreciated by some that other oils used for this purpose.

Further, Bay Laurel essential oil is indicated by some authorities for nerve regeneration (blending with Helichrysum may be useful), as well as rheumatoid arthritis.
