It is estimated that 1500 to 2000 cases of "ginger paralysis" occurred in Oklahoma. The relation of the disease to an adulterated fluid extract of ginger used for beverage purposes is pointed out. Chemical examination of the ginger product revealed the presence of a phenol, probably cresol, and phosphate. Pharmacological tests of the ginger product showed effects in animals similar to those of technical tricresyl phosphate and to the human syndrome of "ginger paralysis.".
