Also, you can get the ground Milk Thistle seed at M/R as well...but I get mine from Pacific Botanicals (as they grown their own right here in the US). Anytime we can choose organic NON-imported herbs, that's the better choice...and Pacific Botanicals growing/organic standards are AWESOME.
I take 3 tablespoons of ground Milk Thistle seeds every day in my Superfood. Standard dosage is 1-3 tablespoons daily. You can mix it with anything - it has virtually no flavor, just a consistency kinda like sawdust.
