Interesting review paper on plant anxiolytics (pdf):

I recently bought a cheap bottle of capsuled Neem Leaf (Azadirachta indica) just to see if it would do something for my skin problems. I didn't even know it may have anxiolytic effects but after starting the consume of the plant (couple of capsules [1 gram of the whole herb] with meals 3 times a day) yesterday the rest of the day went with profound easiness and my anxiety was very low (can't be placebo since I had no idea of the anxiolytic potential?). I took 4 capsules (2 grams of the whole herb) with my breakfast today and I'm again feeling very nice but not really sedated. It's smooth and soft!
I searched google scholars and found a rat study:

The extract was found to produce significant antianxiety effects (in low doses) comparable to diazepam (1 mg/kg). Yet in high doses it did not show anxiolytic activity. So here's a plant producing benzo-like anxiolysis without abuse potential? Of course one rat study and my personal experiences are not much yet but there is something to it. Its effect can't be direct GABA-agonism since the effect disappears in high doses?
Another study showing neuroprotective effects:
