  • Scientific Assessment of Ephedra Species (Ephedra Spp.)
    Annex 3 Ref. Ares(2010)892815 – 02/12/2010 Recognising risks – Protecting Health Federal Institute for Risk Assessment Annex 2 to 5-3539-02-5591315 Scientific assessment of Ephedra species (Ephedra spp.) Purpose of assessment The Federal Office of Consumer Protection and Food Safety (BVL), in collaboration with the ALS working party on dietary foods, nutrition and classification issues, has compiled a hit list of 10 substances, the consumption of which may pose a health risk. These plants, which include Ephedra species (Ephedra L.) and preparations made from them, contain substances with a strong pharmacological and/or psychoactive effect. The Federal Ministry of Food, Agriculture and Consumer Protection has already asked the EU Commission to start the procedure under Article 8 of Regulation (EC) No 1925/2006 for these plants and preparations, for the purpose of including them in one of the three lists in Annex III. The assessment applies to ephedra alkaloid-containing ephedra haulm. The risk assessment of the plants was carried out on the basis of the Guidance on Safety Assessment of botanicals and botanical preparations intended for use as ingredients in food supplements published by the EFSA1 and the BfR guidelines on health assessments2. Result We know that ingestion of ephedra alkaloid-containing Ephedra haulm represents a risk from medicinal use in the USA and from the fact that it has now been banned as a food supplement in the USA. Serious unwanted and sometimes life-threatening side effects are associated with the ingestion of food supplements containing ephedra alkaloids. Due to the risks described, we would recommend that ephedra alkaloid-containing Ephedra haulm be classified in List A of Annex III to Regulation (EC) No 1925/2006.

  • Dietary Supplements Containing Ephedrine Alkaloids
    SUMMARY OF DATA FOR CHEMICAL SELECTION Dietary Supplements Containing Ephedrine Alkaloids BASIS OF NOMINATION Dietary supplements containing ephedrine alkaloids from herbal sources (ephedra) are brought to the attention of the CSWG as part of an ongoing National Institutes of Health (NIH) Office of Dietary Supplements (ODS) research initiative on the safety and efficacy of these products. This initiative was recommended by the Senate Committee on Appropriations in fiscal year (FY) 2001. In its Report making FY 2002 appropriations for the Department of Health and Human Services, the Committee expressed pleasure that the ODS followed through on its FY 2001 recommendation and urged the ODS to continue and expand this important effort. The nomination of ephedra­ containing supplements to the National Toxicology Program (NTP) is part of the expanded effort by the ODS. As the Senate Committee noted, the number of Americans taking dietary supplements containing ephedra has risen dramatically. Dietary supplements containing herbal ephedra (chiefly Ephedra sinica Stapf.) are widely used as diet aids and athletic performance enhancers, with over 3 billion servings1 sold each year for weight loss alone. The active ingredients in these supplements are primarily ephedrine and pseudoephedrine with small amounts of other ephedrine alkaloids usually present. Ephedra-based diet aids often contain other stimulants, such as caffeine (guarana), as well as salicin, diuretics, and cathartics. Ephedra-containing performance enhancers often contain caffeine and other ingredients, such as chromium picolinate or l-carnitine, and may be consumed with other performance enhancers, such as androstenedione and creatine monohydrate. The ephedrine alkaloids are sympathomimetic amines, a class of compounds with fairly well characterized short to medium term biological activities.

Design: A 9-month, double-blind, randomized control study compared the efficacy and safety of a dietary supplement with ephedra and caffeine to a control supplement. Subjects: Sixty-one healthy, premenopausal women with body mass index (BMI) from 27 to 39 kg/m2 were randomly assigned and received a dietary supplement (40 mg/day ephedra alkaloids, 100 mg/day caffeine, high potency mixture of vitamins, minerals, omega-3 fatty acids) or a control supplement for 9 months. Measurements: Efficacy: changes in body weight, body composition, lipids, insulin, leptin, adiponectin, ghrelin, and self-reports of physical activity, diet and quality of life indices. Safety: blood pressure, heart rate, electrocardiograms, urinalysis, blood histology, serum chemistry measures and self-reported symptoms. Results: Forty-one women completed the study. The treatment group lost significantly more body weight (À7.18 kg) and body fat (À5.33 kg) than the control group (À2.25 and À0.99 kg, respectively), and showed significant declines in heart rate, serum cholesterol, triglycerides, cholesterol to high-density lipoprotein ratio, glucose, fasting insulin, and leptin.

  • Introduction Ephedra Has Been Used Over 4000 Years in China As an Extract from Tsaopen-Ma Huang for Cough and Bronchitis
    Introduction Ephedra has been used over 4000 years in China as an extract from Tsaopen-Ma Huang for cough and bronchitis. Ephedra today is found in over 200 dietary supplements because of its known effective ability to promote weight and body fat reduction. (2) Ephedrine is believed to increase catecholamine levels at synaptic areas in the brain and in the heart, which have a direct stimulatory effect on alpha and beta-adrenergic receptors. Ephedrine will therefore increase heart rate, cardiac output and peripheral resistance and as a result increase blood pressure. (4) However, it has been linked with dizziness, tremors, headaches, irregular heart rates and seizures to myocardial infarctions and strokes. Further, sleeplessness, restlessness, irritability, headache, vomiting, urinary disorders and rapid heartbeat have also been linked with ephedrine use. (4) Doses over 100mg per day are thought to be life threatening because it can trigger a sharp rise in blood pressure and the rhythm of the heart. (1) Combinations with other stimulant such as caffeine have also connected ephedrine to cardiac arrhythmia and ventricular tachycardia. Ephedrine has been linked to ischemic and hemorrhagic stroke and intravenous administration of ephedrine has been linked to acute myocardial infarction. (2) As a result, the NFL, as well as the International Olympic Committee has banned the use of ephedrine in its athletes. In light of the recent Steve Bechler heat stroke tragedy, Major League Baseball is currently trying to decide whether or not to follow in the tracks of the NFL and IOC. The FDA is also increasing its investigative efforts in response to the public's requests to ban ephedrine.
