I know alfalfa is kick-ass for nutritional value. It's known as a very supportive herb. If it does "obliterate" morgellons, unfortunately it's probably just a short-term fix (I call it the "lifeboat manuever") Buy HEY, all info is important.
I suspect that buying rabbit food pellets (which are 100% alfalfa) would be just as good and way cheaper than the food-grade variety.
Just a thought.
