Anyone know any natural remedies to heal diabetic skin ulcers?

No simple answers: This is very complex. Proper diagnosis and treatment is critical to prevent worsening of the problem that could lead to more serious morbidity. Proper evaluation, removal of dead tissue, and good wound care is critical. I would recommend an evaluation by a board certified plastic surgeon who deals with complex wounds including diabetic neuropathy.

Honey!: Manuka honey has been used as a natural remedy for diabetic ulcers and has shown in clinical studies to have antibacterial properties. Of course with any diabetic ulcer you should consult with your doctor prior to any self treatment. Diabetic ulcers can become serious and can lead to amputation if not treated properly.

Diabetic ulcers: Honey. There is a product out called medihoney. Which is medical grade honey that helps heal ulcers.

Wound care. : Diabetic ulcers will generally heal if you offload the area (decrease direct pressure with an insert, or a wheelchair), have your doctor trim the callus and dead tissue away on a regular basis, and if the ulcer is infected, you may need oral or IV antibiotics, depending on the severity of the infection.

Diabetic Foot Treat: Do not try to treat a diabetic foot infection with home remedies without at least having a professional observing as the consequences of an unsuccessful treatment can mean hospitalization, amputation or overwhelming sepsis and death. There are over 4000+ wound care products that are available so even among professionals, opinions vary. Attention to underlying causes of the ulceration are paramount.
