I'm a bit confused about extracts and powders. "3 teaspoons a day of each" is about powder? And "1 teaspoon a day of each" is about extract?

Hello. No, that isn't it. It's nothing to do with extracts. Let me explain. There are two kinds of herbal powders, powdered herb and dried and powdered herb. I'm assuming that the powders you were thinking of buying were the first of these, powdered herb, i.e. seeds which are simply ground into powder. In this case it's the 3 teaspoons a day. If on the other hand you were getting dried and powdered herb, i.e. seeds which are both dried and ground, then this kind of powder would be more concentrated, so in this case it would be the 1 teaspoon a day.
