I know there was no fertilizer on MY lawn, but I do get alot of water running through this area of the yard from an unmaintained field behind the house.
I didn't juice the roots but I cut the grass about 3 inches above ground. I might have had a few pieces that were down a little farther.
I drank 1.5 oz on saturday but I had probably 3-4 ounces on sunday when I got sick. It was Friday before I was 100% back to normal and I am very healthy, I rarely ever get sick in anyway.
