This was the top pinned image of the month! I love it when the image contains the instructions too. I just ordered some lavender essential oil on Amazon (this one is the #1 best seller and has great reviews).
Herbal Remedies for Shingles, this mentions using Tea Tree Oil, but it does not mention adding B12 in tablet form. An old country doctor told my mother (a nurse) to use both on her Uncle who had shingles and it cleared right up. I had shingles in 2008 and remembered my mother with her uncle, so I did the same with mine, and the combination of TTOil externally and B12 tablets cleared mine up in short order!
