Do you consider Theanine to be a herb? It is extracted from a plant/occurs naturally.
Theanine (about 400mg-600mg) is the most effective natural substance for anxiety as far as I have experienced. I think it even trumps chamomile which I find to pretty much just make me tired, not actually reduce anxiety. Theanine tends to make me feel more calm and focused, I think. At the 400-600 range, it helps moderately with stoping racing thoughts. I find that exceeding 600 starts to have a numbing and unpleasant effect with less effect on racing thoughts, though, so I wouldn't recommend any more than that. I don't think it is very helpful for something like every day anxiety since it isn't very strong, but it can make attacks of anxiety more manageable.
I can understand being afraid of SSRIs, as I am too, but there are plenty alternatives that will be more effective than herbs. Especially if the anxiety is diminishing your quality of life significantly, the few side effects of things like Vistaril or SSREs will probably worth bearing, and AFIK, they don't have any of the long term side effects of SSRIs, so if you didn't like them, you could get off them. Of course, I realize it is not always easy to find a doctor who is liberal about this sort of thing, but if you can find one who isn't fixated on SSRIs, then this is something to seriously consider.
Also, have you tried CBT? Some people are helped a lot by it, and it has no side effects at all.
