Disagree strongly. Many cultures outside the west have diets that include garlic, cloves, curry, coconut oil, etc. that parasites don't like... Organic sheep farmers are using garlic juice.
It used to be that humans were dewormed every 6 months when most folks lived on farms... we no longer do that. My grandparents and parents were farmers.. they used castor oil. Line up the kids, down it goes. in the ears and in the nose. like it or not. Just like the animals.
