Q. Can you help me find peer-reviewed articles on the plant Tagetes Lucida? They need to be about dreams or hallucinations, and also Mexican folklore.

First go to the A-Z Databases: Academic & Scholarly page. 

Within these databases you will find peer-reviewed articles. Research Library, JSTOR and ProQuest Central are larger databases and would be good ones to start off your search:

• Click on one of them and enter search terms "tagetes lucida" (in quotations) in the search bar.  You could also try "tagetes lucida" AND (capitalized) hallucinations. 
• Click both the Full Text and Peer Reviewed boxes under the search bar. 
• Now hit enter to search.
• You can now go through your list of peer reviewed articles to look for ones that match your criteria.
