I know a massage therapist who has recently been diagnosed with carpal tunnel syndrome and wants to avoid surgery so he decided to try a lotion with essential oils and herbal infused fixed oils that may give some relief. I first infused a blend of Jojoba, Apricot Kernel and Evening Primrose oils (all with anti-inflammatory and muscular/neurological relief properties) with Chamomile, Comfrey leaf, Cayenne and White Willow Bark. Then I used this as the oil in the lotion and used essential oils of Yarrow, Sandalwood (sustainable), Rosemary cineole and Peppermint. I'll let you know if it helps. If it does, I'll probably add it to my lotions page. No, actually, I'll probably make it as a salve next time.
One advantage of working in hospice is that I get to play with all the therapy dogs. This is Asher, a Corgi.
