Abstract
- Ma-huang (Ephedra sinica) is a herb that exhibits sympathomimetic activity. We report a patient with acquired myopathy following ingestion of a Ma-huang-based herbal remedy for 6 months. A 50-year-old woman was admitted for progressive muscular weakness. An electrodiagnostic study and muscle biopsy sampling revealed generalized active myopathy with nonspecific inflammation. It appears that Ma-huang, along with Raynaud's phenomenon and pericardial effusion, may be a causative agent of myopathy. As such, attention should be paid to the possibility that herbal medication with Ma-huang can result in myopathy.
