Yes, it sure does help with anxiety, my naturopath does it for mine quite frequently and I can sure tell the difference. I really do not know the complete reasons as to how it works, but, believe me, it sure does.
I got a great result with acupuncture during fertility treatments, and didn't even believe in it. Occasionally I would have an ache or pain (chronic aching shoulders) and the acupuncturist would place a needle for that also while doing the fertility stuff, and I'd go home pain-free. So if it can work for aches and pains and fertility improvement, I don't know why it wouldn't work for anxiety.
