Pharmaceutical: Herba Ephedrae

Cautions: It is prohibited to be used for patients with deficient dyspnea without blockage of the lung qi and should be used with caution for patients with hypertension and insomnia because ephedrine can stimulate central nervous system and raise blood pressure. The Shang Han Lun recommends removing the nodes and decocting Ma Huang first, scooping the foam from the top of the decoction. It has been argued this is to reduce the "vexing" effects although the efficacy of this is debated and rarely done today.

It should not be used in conjunction with MAOIs, central nervous system stimulants, alkaloids ergotamines and xanthines enhancing their effects by acting as a receptor level agonist.

In the UK the maximum daily dose permitted without prescription is 1.8g daily in three 0.6g doses. This makes it difficult to achieve a pharmacologically active effect and must be complemented with other herbs that release the exterior and expel Wind-Cold such as Gui Zhi, Jing Jie, Fang Feng and Zi Su Ye.

Huang Hua Zi (Sida cordifolia), more common in Ayurveda where it is known as Bala बला, also contains ephedrine at lower concentrations and has no legal restrictions placed on it by the UK MHRA. It is considered more cooling, Heat clearing and Damp draining without Exterior Releasing properties in Chinese medicine so best used as a substitute in Warm Diseases, especially Damp-Warm Disease, or supplemented with increased warm Exterior Releasing herbs like those described above.
