Natural Treatment for Keloid Scars

Borax for keloid - I have suffered with a keloid on my ear lobe for 20 years. I have had injections and three surgeries it always comes back. Had radiation.iI came back one year later.I tried Apple Cider Vinegar, would not shake it. Finally I tried a borax paste... borax and water mixed and applied it at night. I left it on.about a few days. It started hurting and shrinking. It shrunk from the inside lobe and is soft, not hard. Almost gone after six months.
