I make all natural creams and oils as well as other items (using essential oils) as my business. I usually test thoroughly before marketing a product. In this case I am not marketing & I am highly qualified to comment for those who are interested in using essential oils. Geranium and Peppermint are often used for neuralgia. Eucalyptus is an anti-neuralgic. Peppermint & Eucalyptus are also analgesics. At the request of another member I began working on something to assist TN flare ups. This morning I developed a mixture that worked for me for about two hours. I used 8ml jojoba oil (sweet almond oil would be my second choice), 2 drops Geranium essential oil, 2 drops Eucalyptus essential oil, & 1 drop Peppermint essential oil. A cream lasts longer than an oil but sometimes does not have the same effects. As I have two badly sprained wrists and face imminent hospitalization, it will be some time before I can make a cream and test it. I thought it best to get this out while I could. Best Wishes to All.
