You should always be careful of what kind of herbs you are buying and where
they are coming from.  Just like anything else.
I make all of my own herbals for just this reason.  There are many companies
out there that will sacrifice quality for the almighty dollar.  Always know
who your source is and where their priorities lie.  It never hurts to get a
little background on the companies that you do business with whatever the
product is, but especially if it is a product that you ingest.
Questions can be forwarded directly to my e-mail or toll-free number.

Wishing you health and wellness!
