Would you not be able to ship products to Canada through a website, MH? I live in Canada and have ordered herbals no problem. They don't usually open it at the border unless they think it's an explosive or something dangerous. At least that's been my experience.
I've also ordered stuff from US health websites before with no problem. Most of them just don't label what's actually in the package, so it looks more like a gift or something bought off of ebay.
