Ukrain ((ウクライナ語:Україн); also called celandine) is the trademarked name of a semi-synthetic substance derived from the plant ''Chelidonium majus'' and promoted as a drug to improve health and treat cancer. It was created in 1978, by a Ukrainian chemist Vasyl Novytskyi. Ukrain is named after the nation of Ukraine and is produced by an Austrian company Nowicky Pharma. According to the American Cancer Society and the Memorial Sloan-Kettering Cancer Center, there is no evidence that Ukrain is an effective cancer treatment. ==Evidence== In 2005, Edzard Ernst led a review into evidence of the effectiveness of Ukrain. Although the review found evidence suggesting the drug was effective, it also concluded that "numerous caveats prevent a positive conclusion". Commenting on the review some years later, Ernst wrote on his blog that the results they were examining had seemed "too good to be true" – and on investigation the trials were very small in size, often seemed to include Novytskyi himself, and had significant methodological flaws. However, despite the cautious conclusion given, "this article became much cited. ... () must have been delighted".〔 The Memorial Sloan-Kettering Cancer Center say that clinical trials suggest that Ukrain might have potential as a future anti-cancer drug, but that its safety and effectiveness are yet to be proven. The American Cancer Society stated that, as of 2013, "available scientific evidence does not support claims that celandine is effective in treating cancer in humans".〔 It may however be responsible for some adverse side-effects including hepatitis and allergic skin reactions.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ukrain」の詳細全文を読む スポンサード リンク
