Emtree terms are a set (thesaurus) of standardized terms that describe the content of articles in Embase. Emtree terms are assigned to each article. Terms are chosen to cover both the central aspects of an article (major headings) and other significant information discussed (minor headings).

By using terms from the Emtree thesaurus, all articles on a given topic can be found regardless of the terminology used by the authors.

Use Emtree to:

• Identify appropriate terms
• Confirm definitions
• Search by a subject
• Build a search strategy
• Apply subheadings
• Focus search results
• Limit or expand retrieval
• Add synonyms recommended by Embase
