It is a phenomena that results when there is an
intensification of the disease symptoms and often an expansionof similar symptoms to other places all of a temporary nature,after which the patient is improved or well. Often it appears to someas if they have the flu, and so is described as "the patient having flu-like symptoms." "Flu-like symptoms" is an over-simplification ofwhat happens in varying cases and with varying patients.
When treating Leishmaniasis, Syphilis or Tuberculosis, the
phenomena is called Herxheimer, when treating Leprosy it's called

It is necessary for the successful treatment of Rheumatoid
Diseases, therefore, that a physician attend the patient who usesour treatment protocol, and that the physician fully comprehendthe distinctions between specific drug toxicities and the Herxheimereffect. This distinction probably can come only through theexperiences of applied clinical practices.
Drugs do have toxicities of their own, but the essential
importance for Rheumatoid Arthritics is to be able todiscriminate between the two: Herxheimer effect and toxicity.
