FYI: St. John's Wort for Sleep

One of St. John's wort's major advantages over prescription antidepressant medications is its ability to promote a better quality of sleep. Unlike St. John's wort, most antidepressants lengthen the time it takes to enter the REM (rapid eye movement) sleep phase, reducing or even eliminating REM sleep. Far from inactive during sleep, the subconscious mind is busy analyzing the day's events and processing feelings during the dreaming or REM phase. This is essential for mental health.
