## Plant Monograph: Mormon Tea
**Name of plant:**
Mormon tea
**Catch phrase (Carmina Gadelica or traditional invocation if available):**
No traditional *Carmina Gadelica* invocation is recorded for Mormon tea. A fitting descriptive phrase is: **“The green tea of the desert, springing where water is scarce.”**
**Family:**
Ephedraceae
**Genus and species:**
*Ephedra nevadensis* S.Watson
**Other names:**
Mormon tea, Nevada jointfir, Nevada ephedra, desert tea, Brigham tea, jointfir, té de varas, tea of the desert. The name “Mormon tea” is also sometimes applied to other *Ephedra* species, particularly *E. viridis*, so botanical identification is important. ([PubMed Central (PMC)][1])
**Brief introduction:**
Mormon tea is an evergreen, highly drought-adapted desert shrub native to the western United States and northern Mexico. Its green, jointed, nearly leafless stems carry out most of its photosynthesis, giving the plant its characteristic broom-like appearance. Indigenous peoples of the American Southwest and Great Basin used several *Ephedra* species as beverages and medicines, and *E. nevadensis* became known in English as Mormon tea. Unlike the Asian medicinal *Ephedra* species traditionally known as ma huang, *E. nevadensis* contains little or no ephedrine-type alkaloids, making it chemically quite different. ([PubMed Central (PMC)][1])
**Traditional uses:**
* Prepared as a pleasant, aromatic tea from the green stems.
* Used traditionally as a beverage and general tonic.
* Employed by Indigenous peoples of the Southwest in traditional medicinal preparations.
* Used traditionally for urinary and fluid-related complaints.
* Infusions of *Ephedra* species were used traditionally for respiratory complaints, colds, coughs and related conditions, although evidence and practices vary considerably among species and cultures. ([PubMed Central (PMC)][1])
**Historical use:**
* Indigenous peoples harvested *Ephedra* stems for tea and medicinal preparations.
* Various Indigenous communities prepared the stems as an aromatic beverage by boiling them in water.
* Some western North American *Ephedra* species were historically employed in treatments for sexually transmitted infections, including syphilis and gonorrhea; these historical uses should not be interpreted as evidence of clinical efficacy. ([PubMed Central (PMC)][1])
* Mormon settlers adopted desert *Ephedra* teas as a caffeine-free beverage, contributing to the common name “Mormon tea.”
* Related *Ephedra* species were historically used as stimulants and respiratory medicines, but these traditions primarily concern Asian species such as *E. sinica*, rather than *E. nevadensis*. ([Office of Dietary Supplements][2])
**Parts used and method of use:**
* Young green stems and twigs
* Occasionally seeds or other plant material in ethnobotanical contexts
Used as:
* Infusion or decoction of the stems as a tea
* Fresh or dried stems boiled in water
* Traditional external preparations in some regional ethnobotanical practices
* Culinary beverage rather than a concentrated medicinal extract
**Use in healing (modern herbal practice):**
* Traditionally regarded as a mild urinary or “cleansing” tea.
* Historically used for respiratory and cold-related complaints within broader *Ephedra* traditions.
* Sometimes described in herbal literature as a mild diuretic.
* Investigated primarily as part of research into the chemistry and pharmacology of the *Ephedra* genus.
* Modern medicinal claims should be made cautiously because clinical research specifically on *E. nevadensis* is sparse and should not be extrapolated from *E. sinica*. ([PubMed][3])
**Pharmacology and biochemistry:**
* Ephedrine and related alkaloids — present in little or no appreciable amount in *E. nevadensis*, unlike important Asian medicinal *Ephedra* species. ([Office of Dietary Supplements][2])
* Flavonoids and phenolic compounds — constituents found across the *Ephedra* genus.
* Other non-alkaloidal constituents, including terpenoid and phenolic compounds, contribute to the chemical diversity of the genus. ([PubMed][3])
Mechanisms:
* The sympathomimetic effects associated with ephedrine-containing *Ephedra* species arise primarily through adrenergic receptor stimulation and increased noradrenergic activity; these mechanisms should **not** automatically be attributed to *E. nevadensis*.
* Polyphenolic constituents of *Ephedra* species may contribute antioxidant and anti-inflammatory activity in experimental models.
* Diuretic and other pharmacological effects have been reported for *Ephedra* preparations generally, but species-specific evidence for *E. nevadensis* remains limited. ([PubMed][3])
Overall profile: *Ephedra nevadensis* is principally a traditional desert beverage plant rather than a modern substitute for ephedrine-containing medicinal *Ephedra*. Its reputation for stimulant activity is frequently confused with that of Asian *Ephedra* species. Analytical research specifically identifies *E. nevadensis* as containing little or no ephedrine-type alkaloids. ([Office of Dietary Supplements][2])
**Common dosage:**
* Dried stem infusion: approximately 1–2 g dried stems per 250 mL water, traditionally steeped or gently boiled.
* Strong decoction: approximately 2–4 g dried stems per 250 mL water, used traditionally as a beverage.
* Fresh-stem tea: a small handful of cleaned young stems per cup of water.
* Concentrated extracts: **no standardized medicinal dosage established for *E. nevadensis***.
**Safety factors (including side effects):**
* Correct botanical identification is important because “Mormon tea” is a common name applied to several *Ephedra* species with substantially different alkaloid profiles.
* The safety profile of *E. nevadensis* is not as well characterized clinically as that of the extensively studied Asian species.
* Concentrated extracts should not be assumed to be equivalent to the traditional beverage.
* People with cardiovascular disease, hypertension, arrhythmias or significant renal disease should exercise particular caution with medicinal *Ephedra* preparations.
* Long-term medicinal use has not been adequately established; traditional beverage use should not be equated with evidence supporting chronic concentrated supplementation.
**First aid / adverse reaction response:**
* Palpitations, rapid heartbeat or marked agitation: discontinue use and seek medical assessment; urgent care is appropriate if symptoms are severe or persistent.
* Dizziness, weakness or fainting: stop use, sit or lie down, and seek medical attention if symptoms are significant.
* Nausea, vomiting or abdominal distress: discontinue use, hydrate as appropriate, and obtain medical advice if severe.
* Suspected allergic reaction, especially facial swelling or difficulty breathing: seek emergency medical care immediately.
**Drug interactions:**
* Because some plants sold under the name “Mormon tea” may contain ephedrine alkaloids, products of uncertain botanical identity should not be combined casually with stimulant or sympathomimetic medicines.
* Potential additive cardiovascular effects are a concern with stimulant medications and decongestants if an ephedrine-containing *Ephedra* species has been substituted.
* Caution is appropriate with medicines affecting blood pressure or heart rhythm when the botanical identity or chemical composition of the preparation is uncertain.
* Traditional *E. nevadensis* tea should not be assumed to have the same interaction profile as ephedrine-containing *Ephedra* products; chemical composition varies substantially among species. ([Office of Dietary Supplements][2])
**Horticultural requirements:**
* USDA / Canadian zone: Approximately USDA Zones 4–10, depending on provenance; hardy, cold-tolerant populations occur within its natural range.
* Soil pH: Approximately 6.0–8.0; tolerant of alkaline and calcareous desert soils.
* Light requirements: Full sun.
* Moisture: Very low once established; exceptionally drought tolerant.
* Other notes (growth habit, harvest timing, etc.):
* Growth habit: Slow-growing, evergreen, dioecious desert shrub with green, jointed, photosynthetic stems and greatly reduced leaves.
* Flowering/fruiting: Small reproductive structures occur at the joints of the stems; female plants produce characteristic fleshy seed-bearing structures.
* Harvest timing: Young green stems may be harvested during the active growing season; sustainable harvesting should leave sufficient living material on the plant.
* Habitat: Deserts, dry slopes, washes, rocky plains and other arid habitats of western North America.
* Propagation/cultivation notes: Requires excellent drainage, intense sunlight and very little supplemental water once established. Seed propagation is possible but germination can be slow; cuttings may be used under suitable conditions.
**Sampling of clinical reports / studies:**
* **Clinical evidence:** There is little high-quality clinical research specifically examining *E. nevadensis* as a therapeutic agent. Much of the clinical literature concerning “Ephedra” involves Asian species containing substantial ephedrine alkaloids and therefore cannot simply be applied to Mormon tea.
* **Pharmacological study:** Reviews of the *Ephedra* genus report antioxidant, anti-inflammatory, antimicrobial, diuretic and other experimental activities, but emphasize the substantial chemical diversity between species. ([PubMed][3])
* **Phytochemical study:** Analytical studies demonstrate that ephedrine alkaloid concentration varies markedly between *Ephedra* species and preparations; *E. nevadensis* is specifically identified as containing little or no ephedrine-type alkaloids. ([Office of Dietary Supplements][2])
* **Ethnobotanical evidence:** Ethnobotanical literature documents *E. nevadensis* and related North American *Ephedra* species as traditional beverage and medicinal plants, including use of the stems for tea. ([PubMed Central (PMC)][1])
* **Overall assessment of evidence:** Strong evidence exists for the historical and ethnobotanical importance of Mormon tea as a beverage plant; evidence for specific modern therapeutic indications is limited. The distinction between *E. nevadensis* and ephedrine-rich Asian *Ephedra* species is essential when interpreting both efficacy and safety. ([Office of Dietary Supplements][2])
