  • Ephedra, an extract of the plant Ephedra sinica also known as ma huang, has been used as a herbal remedy in traditional Chinese medicine for the treatment of asthma and hay fever, as well as for the common cold. Ephedra is a stimulant that constricts blood vessels and increases blood pressure and heart rate. Several additional species belonging to the genus Ephedra have traditionally been used for a variety of medicinal purposes and are a possible candidate for the Soma plant of Indo-Iranian religion. [North American ephedras lack the alkaloids found in species such as E. sinica. ] Ephedra-containing dietary supplements have been linked to a high rate of serious side effects and a number of deaths, leading to concern from the U.S. Food and Drug Administration (FDA), the National Center for Complementary and Alternative Medicine, and the medical community. However, initial efforts to test and regulate ephedra were defeated by lobbying and political pressure from the dietary supplement industry. Ultimately, in response to accumulating evidence of adverse effects and deaths related to ephedra, the FDA banned the sale of ephedra-containing supplements on April 12, 2004. Following a legal challenge by an ephedra manufacturer, the U.S. Court of Appeals for the Tenth Circuit upheld the FDA's ban of ephedra in 2006. The sale of ephedra-containing dietary supplements remains illegal in the United States due to evidence of adverse ephedra-related effects. Following the FDA's ban, the supplement industry has marketed "ephedrine-free" or "legal" ephedra products, in which the ephedra is replaced with other herbal stimulants such as bitter orange.
  • Las efedráceas (Ephedraceae) son un familia de arbustos muy ramificados, similares a la retama, habitualmente dioicos, los que se distribuyen en zonas templadas y cálidas del Mediterráneo y de las regiones áridas de Asia y América. Comprende un único género, Ephedra, con unas 35 especies.
  • 麻黃科只有1属约65种，是麻黃目（Ephedrales）的唯一科，分布在亚洲、美洲、东南欧洲和北非等干旱和荒漠地区，中国有12种，主要生长在西南、西北、华北至东北干旱山地和荒漠中。 本科植物为灌木或亚灌木；多分枝，小枝对生或轮生，绿色；单叶对生，通常退化为膜质的鞘；花单性，雌雄异株，雄花有2－4裂的假花被，雌花有一个顶端开口的囊状假花被，发育成革质假种皮；果实为假浆果状。 本科植物多数含有生物碱，可以入药，其中最著名的麻黄（E. sinica Stapf）是重要药材。此外可以固沙保土，“麻黄果]]可以食用。传统上本纲植物属于裸子植物门，但比裸子植物进化，木质部有导管，孢子叶球有盖被，最新的分类将起单独列为一个门。
  • Les plantes du genre Ephedra sont de petits arbustes presque toujours dioïques, très ramifiés, aux tiges articulées. Les fleurs sont petites, jaune verdâtre, les ovules sont enfermés dans une enveloppe assimilable à un ovaire imparfait. Si on peut rencontrer de nombreuses espèces du genre Ephedra en Amérique du Nord, deux espèces sont notables en France et en Suisse, c'est le raisin de mer nommé ainsi à cause des écailles charnues rouges comestibles qui recouvrent les graines et Ephedra major ou E. nebrodensis. Le premier de ces arbrisseaux trapus se rencontre dans les zones côtières sablonneuses de l'ouest et du sud de la France, le second est méditerranéen mais peut atteindre les étages collinéen et montagnard (Marcel Saule - La Grande Flore illustrée des Pyrénées).
