Maybe 10 years ago I discovered Borax on this site for detoxing metals. An unexpected side effect was my TMJ disappeared within the first week. I'm surprised that after 10 years, I still don't see TMJ listed as something else borax cures, so I'm adding it here myself! TMJ is basically untreatable through conventional methods so to be able to open my mouth fully again with no pain or even tightness is a miracle to me! I hope others will find relief too.
I follow Ted's Borax protocol of 1/8 tap in 1 liter of distilled water 5 days a week for 4 weeks. I've had to repeat the protocol a few times over 10 years.
