Ephedra

Ephedra sinica

also known as ma huang

Moderate (respiratory) — but with a documented history of harm

A shrubby desert plant called ma huang in traditional Chinese medicine, used for asthma and respiratory complaints for over five thousand years. Ephedra contains ephedrine, a compound that opens airways and stimulates the cardiovascular system. The traditional Chinese use (in carefully formulated combinations, for short courses, in ill people) is different from the supplement-aisle use that caused dozens of deaths in the late 1990s and early 2000s. The FDA banned dietary supplements containing ephedrine alkaloids in 2004, after the death of a young baseball player and many others.

  • Long traditional Chinese medicine use for asthma, bronchitis, and respiratory infections — almost always in formulas with balancing herbs
  • Ephedrine, isolated from ephedra, was the source of pseudoephedrine — the same decongestant in over-the-counter cold medications today
  • Opens constricted airways — the basis for both the traditional asthma use and the original asthma medications
  • Pharmaceutical ephedrine remains in legitimate medical use as an injectable in surgery for blood pressure support
FDA banned dietary supplements containing ephedrine alkaloids in 2004 after dozens of deaths — heart attacks, strokes, seizures, and arrhythmias
The 2003 death of MLB pitcher Steve Bechler at age 23 from an ephedra-containing supplement helped trigger the ban
Combined with caffeine (a common stack in weight-loss formulas) the cardiovascular risk multiplied
Pharmaceutical ephedrine for legitimate medical use is regulated separately and remains available
Pseudoephedrine in cold medications is a different molecule and behaves more gently, though it carries its own cardiovascular cautions
Traditional Chinese formula use of ephedra (under TCM practitioner guidance, in short courses, in formulas with balancing herbs) has a different safety profile than supplement-aisle use
If in doubt, use safer respiratory herbs — mullein, thyme, marshmallow — without the cardiovascular profile
Skip with any heart condition, high blood pressure, anxiety disorder, or thyroid disease
Skip during pregnancy and nursing
Skip with stimulant medications, MAOIs, or anesthesia
