- Using it as a general term for any herb.
- Pronouncing it as /məˈhuːŋ/.
- Assuming it is commonly understood without explanation.

Frequently Asked Questions
The legality of mahuang and its derivatives (ephedrine) varies by country. It is often restricted or banned in dietary supplements due to safety concerns, but may be regulated for medicinal use.
The primary active alkaloid is ephedrine, a stimulant and bronchodilator.
While historically used for cold symptoms, self-medication with mahuang is strongly discouraged due to significant cardiovascular risks and potential side effects. Always consult a qualified healthcare professional.
Mahuang specifically refers to Ephedra sinica and a few related species used in TCM. 'Ephedra' is the broader botanical genus name, which includes non-medicinal species.
