We buy US organic and lab certified because it has just gotten that way.

There is a BIG time herb supplier that handles tons of stores and practitioners - and offers no gaurantees that what you got sold is even what it was listed as.

Practitioners and stores can plan on having to move in that direction. There are good suppliers and more all the time.

It costs about $200 to have a crop tested. The outside sources we do use provide the certificates on request.
