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. Bay Laurel (and other essential oils of Mediterranean plants) were the subject of research into possible anti-viral activity. Bay Laurel was noted to have 'interesting' anti-viral action against the SARS coronavirus, or SARS-CoV, which causes severe acute respiratory syndrome.

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. Laurel leaf essential oil can be safely used as an immune system support agent, particularly when one may be exposed to higher-risk situations, or may find their immune system depleted from traveling or stress.

Further, Bay Laurel essential oil is indicated by some authorities for nerve regeneration (blending with Helichrysum may be useful), as well as rheumatoid arthritis. The oil has a lovely aroma, and would make an excellent addition to arthritis/joint/muscular formulas not only due to its therapeutic action, but its beautiful spicy & herbaceous scent!
