Ephedra Root — Safety & Interactions
Ma Huang Gen · Radix Ephedrae
Use with caution. Practitioner review recommended before use.
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
