Numerous herbal antidepressants are available quite easily both on the Internet and as over-the-counter herbal remedies for depression, but it is rather difficult to trust most of them. Actually only a small number of them are of any real value, because most of the others are not supported by evidence of their being effective through extensive clinical studies. Some of the herbal antidepressants may claim some scientific support, but that support is based on insufficient statistical data or on clinical studies that are inconclusive or not extensive enough to produce valid results.
