Consumption of Ephedra alkaloids has been prohibited in-competition by the World Anti-Doping Agency (WADA). In Taiwan, colds are often treated with Chinese herbal formulae containing Herba Ephedrae. We screened the products sold in Taiwan and preliminarily assessed their relationships with WADA threshold violations. Fifty-six concentrated powder products, including 19 Chinese herbal formulae that contained Herba Ephedrae, were collected. The content of Ephedra alkaloids, namely ephedrine (E), methylephedrine (ME), norpseudoephedrine (NPE; cathine), pseudoephedrine (PE), and norephedrine (NE; phenylpropanolamine), was determined using a validated high-performance liquid chromatography method...

 We aimed to test the clinical usefulness of ephedrine alkaloids-free Ephedra Herb extract (EFE), which has been proven to be effective and safe in animal studies. First, we performed a safety trial with 7 healthy volunteers, and increased white blood cell counts were observed in 2. However, it was unknown whether this observation was a result of EFE administration. Then, we implemented a controlled, double-blind, randomized crossover trial as the second safety trial for EFE. The trial was conducted under strict conditions, and the participants were managed in the hospital and monitored using an increased number of endpoints...

 Ephedra Herb is classified "pungent, slightly bitter, and warm" in tastes and natures, and is used to provide warmth to the body, dispel coldness, remove dampness, and reduce pain. Similar herbs are "pungent and hot" chili peppers, "pungent and hot" evodia fruit," "pungent and warm" ginger, "pungent and hot" processed ginger, "pungent and hot" Zanthoxylum fruit, etc. These herbs are prescribed to provide heat to the outer or inner body. Some pungent components such as capsaicin, evodiamine, gingerol, and shogaol are known to be activators of transient receptor potential vanilloid 1 (TRPV1)...

 Ephedra Herb is defined in the 17th edition of the Japanese Pharmacopoeia as the terrestrial stem of Ephedra sinica STAPF., Ephedra intermedia SCHRENK et C.A. MEYER, or Ephedra equisetina BUNGE (Ephedraceae) which contains more than 0.7% ephedrine alkaloids (ephedrine and pseudoephedrine). The primary effects and adverse effects of Ephedra Herb are traditionally believed to be mediated by ephedrine alkaloids. We recently reported that Ephedra Herb extract (EHE) exhibits antimetastatic and antitumor effects by suppressing the hepatocyte growth factor-c-Met signaling pathway through the inhibition of c-Met tyrosine kinase activity...

 Ephedra Herb is a crude drug for the treatment of headache, bronchial asthma, nasal inflammation, and the common cold. Although it has been considered that ephedrine alkaloids (EAs) are the principal active ingredients of Ephedra Herb, EAs are known to induce palpitations, hypertension, insomnia, and dysuria as major side effects. Therefore, the administration of EAs-containing drugs to patients with cardiovascular-related diseases is strongly contraindicated. Previously, we isolated herbacetin 7-O-neohesperidoside from Ephedra Herb...

 Ephedra Herb (Japanese name: mao) is defined as the terrestrial stem of Ephedra species. It is one of the most important crude drugs in Kampo prescriptions such as maoto, kakkonto, and shoseiryuto. The traditional biological properties of Ephedra Herb are mainly attributable to ephedrine alkaloids. Recently, our research group has found that Ephedra Herb extract also shows alkaloid-independent pharmacological action; therefore, we focused on polyphenols, other active ingredients of Ephedra Herb extract. Reports on the constituents of the extract other than ephedrine alkaloids are limited, although condensed tannins of procyanidin A-type have been found in some Ephedra species...

Traditional herbal products are widely used in Australia to treat a broad range of conditions and diseases. It is popularly believed that these products are safer than prescribed drugs. While many may be safe, it is worrying that the specific effects and harmful interactions of a number of their components with prescription medications is not well understood. Some traditional herbal preparations contain heavy metals and toxic chemicals, as well as naturally occurring organic toxins. The effects of these substances can be dire, including acute hepatic and renal failure, exacerbation of pre-existing conditions and diseases, and even death...

Restoring dryland ecosystems is a global challenge due to synergistic drivers of disturbance coupled with unpredictable environmental conditions. Dryland plant species have evolved complex life-history strategies to cope with fluctuating resources and climatic extremes. Although rarely quantified, local adaptation is likely widespread among these species and potentially influences restoration outcomes. The common practice of reintroducing propagules to restore dryland ecosystems, often across large spatial scales, compels evaluation of adaptive divergence within these species...

The Ephedra herb, which has been used in Kampo medicines, originates from terrestrial stems of Ephedra species. It is important to establish cultivation methods and cultivars to secure a stable supply of the Ephedra herb that would meet the quality standards for the ephedrine alkaloids content. In this study, we first grew Ephedra sinica plants derived from seeds in the field for 5 years. Then, for selective breeding of cultivars that could meet the quality standards for the ephedrine alkaloids content, we measured the content of total alkaloids (TAs), ephedrine (Eph), and pseudoephedrine (PEph) in individual plants derived from seedlings and grown for 4 years in the field...
