Pinyin: Ma Huang  Chinese: 麻黄
Pharmaceutical: Herba Ephedrae
Taxonomy: Ephedra sinica seu intermedia seu equisetina
English: Ephedra Stem / Joint Pine / Joint Fir / Mormon Tea / Brigham Tea

Tastes: Pungent, slightly bitter, warm
Meridians Entered: Lung and Bladder

Actions & Indications:

1. Induces sweating and releases the Exterior
   Taiyang Stage Wind-Cold Invasion of the Lung, with anhidrosis, chills, fever, headache and a tight, floating pulse
2. Disseminates and facilitates Lung Qi, calms wheezing and stops coughing
   Wind-Cold Obstructs Lung Qi
3. Promotes urination and reduces oedema
   Externally generated oedema
4. Warms and disperses Cold pathogens
   Wind-Cold Bi
   Cold extremities (Reynaud's disease)
5. Breaks up concretions, firmness, accumulations and gatherings (Shen Nong Ben Cao Jing)
   Yin sores that are firm, deeply rooted and without a head

Standard Dosage: 1.5-9g in decoction to release the exterior, and 10-15g for the treatment of oedema. Maximum dose is 20g. Toxic dose is considered to be 30-45g but side effects and risks are possible at any dosage.
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.
