国外植物药质量控制战略及对我国中药发展的启示 总被引:1,自引:0,他引:1
欧盟对植物药的定义为单一或多种植物配伍,含有专一活性成分和(或)植物提取物,用于医疗目的的医疗产品。目前,植物药已成为世界医药市场的一个重要组成部分。然而,在全球植物药市场中,我国的植物药所占份额落后于其他国家,在国际植物药市场中占主导地位的是欧洲草药制剂和日本汉方制剂。我国有中药12807种,其中药用植物类达11146种, 相似文献

基于"欧盟草药专论"解析中药欧盟注册关键问题 总被引:7,自引:5,他引:2
欧盟2004/24/EC法令针对传统草药药品实行简化注册程序,很大程度降低了草药药品上市门槛,但法令为其额外设定的注册条件,如草药在欧盟至少药用15年历史要求、适应症限制、给药途径限制等,对非欧洲本土来源的中药产品而言仍面临诸多挑战.鉴于"欧盟草药专论"的评价与草药药品简化注册中安全性和有效性的审评标准基本一致,首次从欧盟草药专论的角度,跟踪欧盟草药专论最新评价进展,对影响欧盟草药专论建立的关键因素以及中药产品简化注册过程中的关键问题进行深入分析,并提出建议与对策,以期为中药产品欧盟注册提供一定指导和参考. 相似文献

Botanical and cosmeceutical therapies are commonly used to treat symptoms of rosacea such as facial erythema, papules/pustule counts, and telangiectasia. These products may contain plant extracts, phytochemicals, and herbal formulations. The objective of this study was to review clinical studies evaluating the use of botanical agents for the treatment of rosacea. MEDLINE and Embase databases were searched for clinical studies evaluating botanical therapies for rosacea. Major results were summarized, and study methodology was analyzed. Several botanical therapies may be promising for rosacea symptoms, but few studies are methodologically rigorous. Several plant extract and phytochemicals effectively improved facial erythema and papule/pustule counts caused by rosacea. Many studies are not methodologically rigorous. Further research is critical, as many botanicals have been evaluated in only one study. Botanical agents may reduce facial erythema and effectively improve papule/pustule counts associated with rosacea. Although promising, further research in the area is imperative.

Constipation affects 14% of the adult population globally, mainly women, and significantly impacts on health‐related quality of life. The causes of constipation are mainly three: lifestyle related (functional constipation), disease related, and drug induced. Constipation can generate considerable suffering, including abdominal pain and distension, anorexia, and nausea. The value of some therapeutic measures such as increased fluid intake, physical activity, diet rich in fiber, and nutritional supplements recommended for the relief of constipation is still questionable. The treatment of constipation can be carried out not only with traditional drugs but also with herbal medicines or with nutraceuticals, which are used to prevent or treat the disorder. We have reviewed the most common botanical laxatives such as senna, cascara, frangula, aloe, and rhubarb and their use in the treatment of constipation. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Review of the Botanical Characteristics,Phytochemistry, and Pharmacology of Astragalus membranaceus (Huangqi) 总被引:1,自引:0,他引:1

Astragalus membranaceus is one of the most widely used traditional Chinese herbal medicines. It is used as immune stimulant, tonic, antioxidant, hepatoprotectant, diuretic, antidiabetic, anticancer, and expectorant. The current paper reviews the botanical characteristics, phytochemistry, and pharmacology of Astragali Radix. Information on Astragali Radix was gathered via the Internet (using Google Scholar, Baidu Scholar, Elsevier, ACS, Medline Plus, CNKI, and Web of Science) as well as from libraries and local books. More than 100 compounds, including flavonoids, saponins, polysaccharides, and amino acids, have so far been identified, and the various biological activities of the compounds have been reported. As an important traditional Chinese medicine, further studies on Astragali Radix can lead to the development of new drugs and therapies for various diseases. The improvement of its utilization should be studied further. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

目的考证药用朱砂的基源、炮制、矿种等,比较药用朱砂的古今质量差异,调查朱砂的生产现状。方法文献查阅和实地调研。结果药用朱砂为天然朱砂;灵砂、银朱为人工朱砂,药性及适应症均不同于天然朱砂,不同的HgS晶型可能是导致朱砂与人工朱砂药性药效差异的重要原因,人工朱砂不能与药用朱砂混用。明确产地和炮制方法是保证药用朱砂安全应用的有效手段。结论古今所用的药用朱砂来源基本一致,朱砂矿伴生矿物较复杂,Pb等伴生元素及矿石中可能夹杂铁是造成药用朱砂毒性和使用前需要吸尽铁杂质及炮制的重要原因之一。 相似文献
