As of 2015, there is no conclusive evidence that people can use apple cider vinegar as a shingles treatment. However, Everyday Health suggests using apple cider vinegar for shingles because it prevents skin irritation by promoting blood circulation, regulating blood pH and preventing bacterial infection.
Everyday Health also claims that apple cider vinegar has the potential to clear out the skin, making it smooth and supple. Other websites, such as WebMD, indicate that there is insufficient evidence for the treatment of shingles using apple cider vinegar. Although Mayo Clinic does not recommend the use of apple cider vinegar for the treatment of shingles, it does recommend the use of lidocaine as a numbing agent.
