Two patients with acute disseminated encephalomyelitis after repeated injection of extracts from several different plants are described. There was no evidence of prior infection or vaccination. Both patients recovered rapidly after treatment with methylprednisolone. Acute disseminated encephalomyelitis should be considered a rare complication of parenteral therapy with herbal extracts.
