Search methods
We searched the following databases up to August 2012: Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane
Library, MEDLINE (from 1946), EMBASE (from 1974), AMED (from 1985), and LILACS (from 1982). We also searched online
trials registers and checked the bibliographies of included studies for further references to relevant trials. We corresponded with trial
investigators and pharmaceutical companies to try to identify unpublished and ongoing trials. We performed a separate search for
adverse effects of evening primrose oil and borage oil in November 2011.
