how about go research it yourself? since you felt ur friend's help wasn't trustworthy. i am into herbal medicines only and nothing else. i have heard good things about valerian root and how it helps with anxiety, although, i have not taken it yet. there are library books you can read on plant medicine.

check out naturalnews.com, mercola.com, earthclinic.com, and curezone.com

herbs and drugs do not mix never will! the drugs will kill the plants' medicinal properties if you mix it with drugs. lavender oil is great for anxiety you could use that i am using it for stress but still have anxiety issues
