"i turned to st. john&#039;s wort after i was prescribed anti depressant medication following the breakdown of my marriage. after a few days of taking the prescribed medication i didn&#039;t like the way it started to change me as a person and feeling out of control. i turned to st. john&#039;s wort after reading details of worldwide clinical trials. i now tend to use when i know i am going to be susceptible to a period of depression and find it really helps. my tip would be to try different brands as they are not all the same!"
