Google and the Russian search engine Yandex are not necessarily reliable sources of health-related information. Often the small text snippets that appear as previews of search results contain inaccurate or insufficient information. Information on home remedies and so-called alternative treatments is particularly problematic, according to researchers from the Martin Luther University Halle-Wittenberg (MLU) in Germany and the Ural Federal University in Russia. The scientists are therefore advocating for clearer warnings about possible health risks.
