The best information I've found for Myasthenia Gravis (MG) is at www.health-science-spirit.com See info. On the critical importance of trace mineral manganese (not to be confused with magnesium) for MG as well as much other helpful info. It also discusses the negative detrimental effects of floride as in florinated water, tooth paste etc. On MG. Thank you to Earth Clinic and to all fellow searchers. God bless!
