This page in a nutshell: Ideal sources for biomedical material include literature reviews or systematic reviews in reliable, third-party, published secondary sources (such as reputable medical journals), recognised standard textbooks by experts in a field, or medical guidelines and position statements from national or international expert bodies. Cite reviews, don't write them.

Biomedical information must be based on reliable, third-party published secondary sources, and must accurately reflect current knowledge. This guideline supports the general sourcing policy with specific attention to what is appropriate for medical content in any Wikipedia article, including those on alternative medicine. Sourcing for all other types of content – including non-medical information in medicine-articles – is covered by the general guideline on identifying reliable sources.

Ideal sources for biomedical information include: review articles (especially systematic reviews) published in reputable medical journals, academic and professional books written by experts in the relevant fields and from respected publishers, and guidelines or position statements from national or international expert bodies. Primary sources should generally not be used for medical content, as such sources often include unreliable or preliminary information; for example, early lab results that do not hold in later clinical trials.

See the reliable sources noticeboard for questions about reliability of specific sources, and feel free to ask at WikiProjects such as WikiProject Medicine and WikiProject Pharmacology.
