@ Fibrilink: Most herbs in these formulas are prepared so freshness isn't such an issue as they are dried, ground up, mixed and then formed into balls with molasses to make teapills so as long as they aren't past their expiry date they should be fine. Just stay away from LanZhou Foci brand (brown box) because they are cheap and the results will be markedly decreased compared to other brands. Black pearl are the best but not always available everywhere so shop around. If your unsure just post the link to them here.
@eljtheblancoassassin: No problems, anytime.
