Ma Huang Dosing
In 2004, the FDA determined that ma huang was unsafe. Because there were reports that ma huang caused dangerous side effects when it was taken in low doses for a short period of time, there are no ma huang dosing guidelines that are considered to be safe and effective. You should also be cautious when buying any herbal supplement (including ma huang), as the label on the bottle may not correctly reflect what is in the bottle.
Ma Huang Dosing: An OverviewA safe and effective ma huang (ephedra) dosage cannot be recommended. The FDA banned ma huang in 2004, and that ban is still in place. The FDA does not have any authority to ban a supplement unless it can prove that the supplement is unsafe -- it clearly and convincingly showed that ma huang was indeed unsafe. You may hear that ma huang is only dangerous when used for a long period of time or in high doses. However, there have been reports of dangerous side effects in people taking low ma huang doses for a short period of time.
If you decide to use a ma huang supplement, it is important to understand that what you see on the label may not reflect what is in the bottle. For example, some herbal supplements have been found to be contaminated with heavy metals or prescription drugs, and some have been found to have much more or much less of the featured ingredient than their label states. Usually, to avoid such problems, it is recommended to make sure the maker of your herbal supplement is a trusted and reputable manufacturer. However, because ma huang has been banned, no manufacturer that makes ma huang should be considered trustworthy and reputable.
