Hi @soonerchris, Welcome to Connect. My vote leans toward snake oil but then I'm no medical expert. It's good that your mother has you to help her navigate this condition. There is another discussion on neuropathy clinics that you might find helpful here:

-- Neuropathy Clinics: https://connect.mayoclinic.org/discussion/neuropathy-17/

A couple of legitimate sites to learn more about neuropathy and treatments:
-- Neuropathy Commons: https://neuropathycommons.org/neuropathy/neuropathy-overview
-- Foundation for Peripheral Neuropathy: https://www.foundationforpn.org/

Has your mother been diagnosed with neuropathy and on any treatments?
