Zachrisson, Olof, Regland, Björn, Jahreskog, Marianne et al.·European journal of pain (London, England)·2002
Researchers tested whether injections of a substance called staphylococcus toxoid could help people with fibromyalgia and chronic fatigue syndrome (ME/CFS). Over 6 months, 100 patients received either the active treatment or placebo injections. Two-thirds of patients receiving the active treatment reported improvement compared to only one-fifth receiving placebo, suggesting the treatment may help some people with these conditions.
