Abstract: This present invention describes a method of diagnosing and treating neuropathic pain, Bell's palsy, viral sore throat, pain due to burns, including sunburn, and pain and itching due to insect bites with compositions of essential aromatic oils, all of which contain Pelargonium graveolens (also called geranium oil bourbon or GOB). This invention discloses compositions of one or more of five other essential aromatic oils, particularly lavender, bergamot, blue chamomile, eucalyptus and tea tree, which when added to GOB acts synergistically with the GOB. These compositions can be used alone or in a composition with a pharmaceutically acceptable carrier in topical or oral dosage form. The present invention is an improvement in the methods and expansion of uses as stated in the previous United States Patent issued in 1993 entitled “Diagnosis and Treatment of Various Neuralgias” (Frome)—U.S. Pat. No. 5,260,313.
