Tried it and it works, but it's expensive. The one thing this does that the homemade stuff doesn't is allow for use as a mouthwash. But a homemade version of that exists too! It's called brushing with baking soda.........

I'm about to go shower in Hunters Specialties Green and hose down with the homemade concoction to check my scrapes.......we'll see if the big boy came back.
