Phish I trained as a herbalist, so I take quite a complex prescription. I use herbal tinctures (alcoholic extracts of herbs), which I take diluted in water twice daily. The thing with herbal medicine is that as a holistic form of medicine, it takes account of all the health problems you have. So you look at all the problems someone has, and then you choose the herbs that have actions relevant to as many of the issues as possible. Ideally you shouldn't self-prescribe, as you're not impartial, but I do. 
My most recent prescription included these:
Panax ginseng - an amazing (and bloody expensive) herb. It's an adaptogen, which means that it enables the body to better cope with stress, whether that be physical, mental or emotional. It's been the subject of lots of research.
Carduus marianus - liver tonic and healer; essential if you drink too much wine like me... 
Schisandra chinensis - another liver healer and general tonic (can't be too careful..
). Very versatile herb.
Hypericum perforatum - St. John's Wort. TBH it's never worked very well for me, but I've been trying it here in high doses as an adjunctive therapy.
Astragalus membranaceous - a long term immune system stimulant and overall tonic.
Crateagus oxycantha - lowers blood pressure (hypotensive), tonic for the circulatory system.
Angelica sinensis
Paeonia lactiflora
Anenome pulsatilla - these all work to balance and nourish the reproductive system, and all also have a general tonic effect of the body/mind. I also have endometriosis and cyclical breast tenderness, so I chose herbs that help that and also are 'nervines' - working to balance and boost the nervous system.
Vitex agnus castus - the primary herb for any hormonal imbalance; works on the pituitary-adrenal-hypothalmic axis.
That's probably no help at all - sorry!
Some of the classic 'nervine' antidepressant herbs are St John's Wort, Skullcap, Passiflora and Valerian. They work for some people but they don't do enough for me - I need the pharmaceuticals, and then I use the herbs to boost my energy and smooth out my hormonal stuff. I definitely use it as 'complementary' rather than 'alternative' medicine. If you're interested in this, I'd recommend you see a medical herbalist for a proper holistic consultation. If you want to self-medicate, David Hoffmann's "The Complete Illustrated Holistic Herbal" is a really good place to start.
