What do you recommend for anxiety? true calm, passion flower, or kava extract?

Herbal remedies: can help. Others are Valerian Root, and small doses of Melatonin (very small during the day as this is usually used at night to help fall asleep). The cause of anxiety is worth investigating, because anxiety itself is a symptom of other dynamics, physical or mental. Here's a reference: http://www.psychologyproductsandservices.com/page2.html
