According to the experts at the Natural Medicines Comprehensive Database, Cobroxin and Nyloxin are new homeopathic products used for chronic pain. They come as an oral spray and topical gel.
The bad news is that these products contain a “5X homeopathic dilution” of cobra venom. This means that they contain a concentration of about 0.001% cobra venom.

As I discuss in my chapter on “Homeopathy,” in my best-selling book, Alternative Medicine: The Christian Handbook, although virtually all homeopathic products contain no detectable active ingredient (no even a single molecule), these two chronic pain products contain a small amount that could potentially have some effect.

Preliminary research has evaluated cobra toxin given as an injection. But there is no reliable evidence about this homeopathic dose when taken orally or applied topically.

The NMCD advises healthcare professionals, “Until more is known about safety and effectiveness, advise patients not to take these products.”
