Scott: I find myself in the same boat with that philosophy. Sobriety is such a precious thing.
I gave the chamomile tea a try and found it contains some lemongrass and siberian ginseng as well. Is good. But truly I'd also try to keep external additives such as these to a minimum, no matter what the herbalist or health-store owner has to say about their products.
Some are without doubt useful... Thanks again for the input.
