Vitamins, antioxidants, omega fatty acids and capsaicin are natural remedies available for treating neuropathy that is attributed to a variety of causes, including diabetes, nerve trauma or exposure to toxins, explains WebMD. Each remedy can be purchased over-the-counter.
Daily doses of vitamins B1, B6, B12 and folic acid may help nerve pain, claims WebMD. However, it is not advisable to take more than 50 milligrams of B6 daily, as high doses can lead to toxicity, pain or numbness in the hands and legs. 25 milligrams of B1, 500 micrograms of B12 and 1 milligram of folic acid are safe, effective doses.
Alpha lipoic acid, an antioxidant, has been used in Europe for years to treat neuropathy, states the Mayo Clinic. Alpha lipoic acid may reduce the symptoms associated with neuropathy. It may also affect blood sugar levels, and potential side effects include skin rash and upset stomach. WebMD recommends 600 to 1,200 milligrams daily.
Omega-3 fatty acids, naturally present in fish oil, possibly improve neuropathy symptoms and blood flow, and help reduce inflammation, according to the Mayo Clinic. The omega-6 fatty acids in evening primrose oil can potentially encourage the regrowth and repair of damaged nerve cells, states WebMD.
Capsaicin, an ingredient in chili peppers, may reduce nerve pain when applied topically, reports WebMD. Capsaicin cream must be applied three to four times daily for several weeks before an individual experiences an improvement in nerve pain.
