He then told me an amazing story about how the old school farriers used a special method to treat horses if they were sick with some sort of gastrointestinal distress. They would make the sick horse "poo tea" by taking feces from healthy horses and making it into a tea of sorts and then they served this to the sick horses.
Did you see that? “Poo tea”! (I don’t even want to know if this would work with humans.)
