Ephedra viridis

Ephedra viridis, known by the common names green Mormon tea, Brigham tea, green ephedra, and Indian tea, is a species of Ephedra . It is indigenous to the Western United States, where it is a member of varied scrub, woodland, desert, and open habitats. It grows at 900–2,300 metres (3,000–7,500 ft) elevations.

Description

The Ephedra viridis shrub is woody below, topped with many dense clusters of erect bright green twigs. They may yellow somewhat with age.

Nodes along the twigs are marked by the tiny pairs of vestigial leaves, which start out reddish but soon dry to brown or black. The stems are green and photosynthetic. [2]

Male plants produce pollen cones at the nodes, each under a centimeter long with protruding yellowish sporangiophores. Female plants produce seed cones which are slightly larger and contain two seeds each.

Chemistry

Information about the chemistry of this species is contradictory. James D. Adams, Jr. and Cecilia Garcia claim it contains no ephedrine, but that it does contain pseudoephedrine. [3] However, a gas chromatograph analysis of samples conducted by Richard F. Keeler found no measurable amount of ephedrine, pseudoephedrine, norephedrine, or norpseudoephedrine. The toxic symptoms found in his study were consistent with a high tannin content rather than with alkaloid poisoning. [4]

Uses

A tea can be made by boiling the stems, [2] hence the common name, "green Mormon tea".

The plant was used medicinally by both Native Americans and the ancient Chinese (using their own local species of the genus) to treat various afflictions including sexually transmitted diseases such as gonorrhea and syphilis, kidney diseases, and complications with menstruation. [5] [6] Native American tribes such as the Shoshone and Paiute boiled tea using the stem of the plant and combined it with the bark of Purshia tridentata , another shrub. [5]

The Navajo have used the plant as a dye solution to produce a yellowish-green color on woolen rugs, [7] [8] whereas other species can produce a light tan or reddish dye. [9]

In modern medicine, the plant is used to treat sinus illnesses such as hay fever, common colds, and sinusitis. This use is supported by clinical trials, as it is a treatment for bronchial asthma. [6]

Because the plant can be used as an appetite suppressant, it is used illegally by some athletes to lose weight and build muscle. [5]

Because it is toxic, the plant should not be ingested without a doctor’s recommendation. [6]

<span class="mw-page-title-main">Ephedrine</span> Medication and stimulant

Ephedrine is a central nervous system (CNS) stimulant that is often used to prevent low blood pressure during anesthesia. It has also been used for asthma, narcolepsy, and obesity but is not the preferred treatment. It is of unclear benefit in nasal congestion. It can be taken by mouth or by injection into a muscle, vein, or just under the skin. Onset with intravenous use is fast, while injection into a muscle can take 20 minutes, and by mouth can take an hour for effect. When given by injection it lasts about an hour and when taken by mouth it can last up to four hours.

It has been used in traditional Chinese medicine, in which it is referred to as Ma Huang, for more than 2,000 years. Native Americans and Mormon pioneers drank a tea brewed from other Ephedra species, called "Mormon tea" and "Indian tea".

Alnus glutinosa, the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium Frankia alni enables it to grow in poor quality soils. It is a medium-sized, short-lived tree growing to a height of up to 30 metres (98 feet). It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water.

It is used in Ayurvedic medicine, where it is known as kurumthotti.

<i>Ephedra</i> (plant) Genus of gymnosperms in the family Ephedraceae

Ephedra is a genus of gymnosperm shrubs. The various species of Ephedra are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three living members of the division Gnetophyta alongside Gnetum and Welwitschia.

There has been much speculation as to the botanical identity of soma or haoma. Soma is a plant described in Hindu sacred texts including the Rigveda, while haoma is a plant described in the Avesta, a collection of Zoroastrian writings. Both names are derived from the Proto-Indo-Iranian *Sauma. Proposed candidates include various species of plants and or fungi. Traditional etymology of Indian Soma is Somalata used traditionally by the Srauta Brahmins called Somayajis whereas the Avestan Haoma is an Ephedra, which are totally unconnected species sourced from different areas. European researchers suggest other plants, such as the perennial Peganum harmala, Nelumbo nucifera, Cannabis sativa, and the sugarcane species Tripidium bengalense ; while fungal candidates include the fly-agaric mushroom Amanita muscaria, the psilocybin-containing mushroom Psilocybe cubensis, and the ergot fungus Claviceps purpurea. Other scholarly proposals include mixtures of these candidates with each other and with other substances.
