What is ephedra extract used for?
People use ephedra for weight loss and athletic performance. It’s also used for allergies, nasal congestion, asthma, common cold, headache, and many other conditions, but there is no good scientific evidence to support these uses. Ephedra is also unsafe. Ephedra has been banned by the US FDA since April 2004. Ephedrine has stimulant properties similar to those of amphetamine in humans that suggest a mechanism of action involving dopamine release (Martin et al.Accordingly, ephedrine has repeatedly been implicated in adverse and sometimes fatal outcomes despite compliance with recommended dosages. Ephedrine has been likened to other sympathomimetics and controlled stimulants,5 and the FDA cited significant cardiovascular risk in support of their final rule to ban its sale.Because ephedrine is a sympathomimetic and a central nervous system stimulant, it is commonly used as an energy enhancer. Ma huang-containing products are marketed and used to improve aerobic performance and endurance, reduce fatigue, increase alertness, improve reaction time, and even increase strength.The three compounds have a long history of human use. Ephedrine is a stimulant that provides bursts of energy and mental clarity, and it can stave off sleepiness. Atropine and scopolamine are powerful deliriants that can produce hallucinations and out-of-body experiences.
What is Ephedra sinica used for?
Ephedra is a low evergreen shrub with small, scaly leaves. The herb usually comes from the stem and branches of the Ephedra sinica species. Ephedra has a long history of medicinal use in China and India to treat colds, fever, headaches, congestion, coughing, wheezing, and other conditions. Ephedrine or Ma Huang was included in weight loss supplements, as well as in “energy stimulating” beverages along with other plants or substances that also act as central nervous system stimulants, such as Guaraná, Ginseng, Sida cordifolia or caffeine, for example.But just because a supplement comes from natural sources doesn’t make it safe. Ephedra can cause a quickened heartbeat and elevated blood pressure. Side effects include heart palpitations, nausea, and vomiting. More than 800 dangerous reactions have been reported with use of the herb.Prior to the ban, ephedra was an ingredient in some dietary supplements promoted for weight loss, increased energy, and enhanced athletic performance. Bitter orange products became more popular after ephedra was taken off the market and have been promoted as ephedra alternatives.Ephedra sinica (common names: ma huang, yellow horse, sea grape) contains sympathomimetic alkaloids, ephedrine, and pseudoephedrine. II.
Is Ephedra sinica legal?
Ephedra sinica (often referred to as “ephedra” or “ma huang”) is a plant that contains several substances called “ephedrine alkaloids,” which include ephedrine and pseudoephedrine. Ephedra is neither safe nor legal as a dietary supplement. Compared with Ephedra sinica, which contains up to 42 mg/g, these species have very low concentrations of ephedra alkaloids. Ephedra nevadensis S.Plant Ephedra is defined as a plant known for its major alkaloid, ephedrine, which has been used in traditional Chinese medicine for respiratory symptoms and as a weight-loss supplement, as well as to increase energy and fat-free mass among athletes.Ephedra sinica (ma huang) is a plant that has been used in Chinese medicine for thousands of years. You can buy ma huang tea and ephredra herb, but the FDA banned ephedrine-containing products.Common names in English include joint-pine, jointfir, Mormon-tea, or Brigham tea. The Chinese name for Ephedra species is mahuang (simplified Chinese: 麻黄; traditional Chinese: 麻黃; pinyin: máhuáng; Wade–Giles: ma-huang; lit.
Is ephedra stronger than caffeine?
Both stimulate the sympathetic nervous system, but ephedra binds directly to β‑adrenergic receptors, producing a stronger thermogenic effect than caffeine, which primarily blocks adenosine receptors. The combination can be synergistic, yet it also raises the potential for side effects. The FDA has banned dietary supplements containing ephedrine alkaloids because they have serious safety risks. Even in relatively low doses and short-term use, ephedra has been linked to harmful effects like high blood pressure, heart attack, seizure, stroke, and psychosis.Products containing ephedrine are not to be used by people with heart disease, hypertension, diabetes, thyroid disease, enlarged prostate, anxiety and restlessness or glaucoma, people taking monoamine oxidase inhibitors or women who are pregnant or lactating.When taken by mouth: Ephedra is likely unsafe. Ephedra can cause severe side effects, such as high blood pressure, heart attacks, seizures, strokes, irregular heartbeat, and death. Taking ephedra with other stimulants like caffeine increases the risk of severe side effects.Caffeine, which is found in coffee, tea, chocolate, guaraná (Paullinia cupana), and some nonprescription and supplement products, can amplify the side effects of ephedrine and pseudoephedrine. People should avoid combination products containing ephedrine/pseudoephedrine/ephedra and caffeine.
Is ephedrine used in illegal drugs?
Pseudoephedrine and ephedrine are widely used decongestant pharmacy medicines. However, due to their potential for misuse in the illicit production of methylamphetamine (crystal meth) – a class A Controlled Drug – there are legal restrictions on the quantities that can be sold or supplied without prescription. Schedule II drugs, substances, or chemicals are defined as drugs with a high potential for abuse, with use potentially leading to severe psychological or physical dependence. These drugs are also considered dangerous.For instance, ephedrine is a List I chemical that is a precursor to the Schedule II controlled substance methamphetamine. Other List I chemicals are precursors to controlled substances such as fentanyl, lysergic acid diethylamide (LSD), and 3,4-Methylenedioxymethamphetamine (known as MDMA, molly, or ecstasy).
Is ephedra bad for your liver?
Ma Huang and Ephedra species containing ephedrine alkaloids have been linked to multiple potentially severe side effects, including clinically apparent liver injury and has been banned from sale in the United States and elsewhere. Because ephedra is marketed by companies as a supplement (not a drug to treat a disease), the US Food and Drug Administration (FDA) does not regulate its use. However, many serious adverse (bad) effects related to ephedra use have been reported.Accordingly, ephedrine has repeatedly been implicated in adverse and sometimes fatal outcomes despite compliance with recommended dosages. Ephedrine has been likened to other sympathomimetics and controlled stimulants,5 and the FDA cited significant cardiovascular risk in support of their final rule to ban its sale.People use ephedra for weight loss and athletic performance. It’s also used for allergies, nasal congestion, asthma, common cold, headache, and many other conditions, but there is no good scientific evidence to support these uses.The Food and Drug Administration (FDA) banned the sale of ephedra-containing products in April 2004 in response to mounting scientific evidence and the receipt of more than 18,000 adverse-event reports. The U. S. Court of Appeals upheld the ban in 2006, and ephedra sales remain illegal today.Ephedrine is a medication used to manage and treat clinically significant hypotension. It is in the sympathomimetic class of drugs. The FDA-approved primary indication for ephedrine is the treatment of clinically significant hypotension perioperatively.
Does ephedrine boost metabolism?
Ephedrine promotes sympathetic neuronal actions, causing the heart to beat more strongly and quickly [11]. It also increases metabolism and suppresses appetite, thus promoting body fat decomposition [12,13]. Its active component, ephedrine, is a CNS stimulant (1, 2); its immediate effects are attributable to stimulation of dopamine release.Ephedrine is one of the four active components of the herb Ephedra. It is able to induce fat loss via increasing the amount of fat available for fuel as well as by increasing heat expenditure. It has been implicated in increasing the metabolic rate by up to 5% in humans.Its active component, ephedrine, is a CNS stimulant (1, 2); its immediate effects are attributable to stimulation of dopamine release.Because of ephedrine’s structural similarity to methamphetamine, it can be used to create methamphetamine using chemical reduction in which ephedrine’s hydroxyl group is removed; this has made ephedrine a highly sought-after chemical precursor in the illicit manufacture of methamphetamine.
