Actually Cayenne should not be dangerous for diabetics. The reason it feels like it is burning is not actually physical heat, but rather the effect it has on neural receptors for pain. IN FACT, there was a study that used capsaicin cream (the hot part of cayenne) on diabetics with neuropothy of the extremities. It actually started to heal the neuropathy!
Pro tip, capsaicin is expensive. I diffuse organic cayenne (has to be organic, otherwise it is irradiated and wont work) into olive oil. Works great, just do a google search on how to do it. Cheap and easy.
