| Remarks | - The root of Mahuang is called Mahuanggen and is said to be effective in stopping sweating, as opposed to the aerial part, which is supported by the fact that ephedradines have been isolated from it. The Japanese Pharmacopoeia 17th edition defines Mahuang as the terrestrial stem of E. sinica, E. intermedia or E. equisetina. In addition, it contains not less than 0.7% of total alkaloids (ephedrine and pseudephedrine). - In 1998, the Chinese Government issued "A notice of the export control to the products of ephedrines" (Administration of bureau of external economy and trade No. 573). It says the export of Mahuang is prohibited in order to prevent desertification as well as to preserve the resource. Currently China restricts the export of Mahuang. | |||||
