We have two protocols in Forbidden Doctor concerning a locked jaw problem. One deals with parasites, and yes, we all have them. The other is a misalignment problem that might also, in addition to supplement support, utilize an upper cervical correction to C1, the first bone in the neck, from an upper cervical doctor of chiropractic, specifically a NUCCA doctor (nucca.org). It may be that the problem is only a deficiency of ionizable calcium in the tissues of the muscles in the jaw structure. Without enough ionizable calcium (calcium bicarbonate) deep in the tissue, and not the blood, muscles will not contract nor relax properly and that may be the whole issue with this kind of lock jaw problem. The protocol listed here is different than the one addressing parasites. This protocol is designed to allow a better relaxation of the muscles of the jaw. It can certainly be taken in conjunction with the parasite protocol if the case is more urgent.
