6) Study #6: In 1747, James Lind conducted a medical trial in order to find a cure for scurvy. In his study, he divided 12 sailors suffering from scurvy into six groups of two men each. He gave each of the six groups a different remedy for an entire week. One of the treatments was to eat two oranges and one lemon every day; another treatment was to drink a half pint of seawater every day.
