Acupuncture and herbs are effective for the treatment of diabetic peripheral neuropathy. From my decades of experience, I am confident to confirm that a millenia of research by Chinese Medicine scholars produces excellent clinical results for my patients.
Gansu Hospital of Traditional Chinese Medicine (endocrinology department) researchers conducted a controlled clinical trial comparing drug therapy with acupuncture and herbs. Patients receiving both acupuncture and herbal medicine had a total effective rate of 96.67%. Patients receiving Chinese herbal medicine monotherapy had a 73.33% total effective rate. Drug therapy patients had a 53.33% total effective rate for the alleviation of DPN (diabetic peripheral neuropathy). 
All patients were monitored throughout the investigation for adverse effects, including liver and renal function tests. No serious adverse effects were reported in any of the clinical trial groups, indicating a high degree of safety for all three treatment protocols. Outcome measures for the study included nerve conduction tests, TCM (traditional Chinese medicine) syndrome scores, and treatment efficacy rates.
