Parts used:
Herb
Temperature & Taste:
Warm, dry. Pungent, slightly Bitter
Classification:
A. Clear Exterior Wind-Cold
Uses:
1. Clears Wind-Cold, Clears the Exterior:
-wind-cold cold and flu with chills, fever, headache, lack of sweating
-acute and chronic Fever (Tibetan Medicine)
2. Opens the Lungs, Stops Cough and Wheezing:
-Cough and Wheezing from wind-cold
-can be used for Wheezing and Asthma from any cause depending on the medicines it is combined with
3. Clears Cold and Damp, Promotes Urine:
-Edema (especially of an acute nature in TCM)
4. Clears Wind-Cold-Damp, Opens Obstruction, Relieves Pain:
-painful Obstruction of the muscles and joints from Wind, Cold and Damp
-acute muscular and articular Rheumatism
-also toxic sores which don't form a head
-disperses Tumors and Swellings (Tibetan Medicine)
DOSE:
1. Low-moderate doses promote sweat and diffuse the Lungs to stop Cough and Wheezing.
2. Note the froth that forms when boiling should be removed as this part can cause agitation. Some have preboiled Ephedra briefly to remove the froth. This is especially useful when larger doses are used.
3. Large doses of 10–15 grams can be used for Edema and fluid swelling, but expereince shows that large doses are best used with 3 times the amount of raw Gypsum (Shi Gao) to inhibit the diaphoretic effect and promote urine.
In Decoction: 2–9 grams (up to 15 grams as a daily dose)
Of the Powder: 500mg–1 ½ gram
PREPARATION:
1. Removing the Nodes:
Sometimes the nodes are removed; they are said to decrease the diaphoretic effect, so removing them enhances diaphoresis.
2. Hot-water prepared Ephedra:
Steeping in boiling water until the froth rises, then removing the herb and drying lessens agitation, but is slightly weaker to cause sweating.
3. Stir-fried Ephedra:
The herb can be stir-fried with a little water. This reduces the diaphoretic effect, but is better for the Lungs.
4. Honey-fried Ephedra:
This is a way of correcting Ephedra. It is not as dispersing, not as strong to promote sweat, and is milder in effect, but has a secondary strengthening and more prolonged effect on the Lungs.
COMMENT:
The raw herb is stronger to promote sweat and disperse the exterior, but is apt to cause agitation and is more prone to causing side effects. Preparing with hot water, stir-frying and especially Honey-frying has the effect of reducing its sweat-promoting effect but is better for the Lungs and because these preparations are milder in effect, have a wider range of use for Cough and Wheezing. The Honey-fried herb is also slightly tonifying to the Lungs, so is better for Cough and Asthma with deficiency, as long as it is combined with suitable tonic medicines.
CORRECTIVES:
1. Honey, Licorice
2. Tragacanth, Gum Arabic
3. Almonds reduce the drying effect while enhancing the tonic effect on the Lungs. This is enhanced when Licorice is added.
SUBSTITUTES:
1. Hyssop, Adhatoda vasica (Unani)
2. Maidenhair
3. Ficus religiosa bark has been used as a substitute for Ephedra in the Himalayas.

Cautions:
1. Toxic in large doses; 30 grams can be toxic to an adult.
2. It can drain the Lung Qi so should be used carefully in those with deficiency. Combining with Licorice and/or Ginseng can correct this.
3. Not used for sweating or night sweats from deficiency.
4. Not used in Hypertension.
DRUG INTERACTION:
Due to Ephedrine content, may interact with:
1. Caffeine and MAO inhibitors, increasing blood pressure
2. Beta-Blockers (reduces efficacy due to opposing action)
3. Ephedrine medication (such as Sudafed), causing ephedrine toxicity, arrhythmia etc.
4. Steroids (dexamethasone), enhancing clearance thereby reducing effectiveness.
