You basicaly get what you pay for. The Christopher company went commercial many years ago, when the old man died, the entire operation went down hill. His kids all but David wanted to turn it all into a pizza parlor. The new owners over and over made the products as cheap as they could.
If you want to know what their product does today, you will have to call the up. The last time I toured their factory they were using the cheapest imported herbs on earth and I heard they have moved from that location, etc.....basically their reputation went in the gutter so badly I will not even buy their books anymore for resale.
