Hi I'm on 5mg of melatonin every night as perscribed and wanting to drink some chamomile tea with licorice root. Would it be safe to do this every night? Also are there any specific herbs other than St. John's wort and kava kava and wired stuff like that that I need to be careful of? I thought if they were standard like chamomile, peppermint, ginseng, lemon, raspberry, cranberry, etc they were relatively safe to use everyday.
