Diabetic neuropathy is a common complication of diabetes in which the peripheral nerves are damaged.
Capsaicin is the active ingredient in chili peppers.
This systematic review showed that a 0.075% capsaicin cream applied to painful areas 4 times a day for 8 weeks reduces pain intensity and improves pain relief.
Presumably because of the pain relief, the topical application also improved sleep quality.
This study suggests that capsaicin cream could provide real relief for people with diabetic neuropaty.
