Ephedra Root — Safety & Interactions

Ma Huang Gen · Radix Ephedrae

Contraindications

  • Exterior wind-cold or wind-heat disorders that still require venting
  • Sweating caused by replete heat rather than deficiency leakage
  • Use of mislabeled ephedra products that may contain aerial parts instead of true root

Cautions

  • Ma Huang Gen is not interchangeable with stimulant ephedra stem products sold for weight loss or energy.
  • Authentication matters because the root is much less alkaloid-heavy than the aerial herb and confusion between the two changes both safety and function.
  • MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
