The explorer Francisco Hernández wrote that chocolate drinks helped treat fever and liver disease. Another explorer, Santiago de Valverde Turices, believed that large amounts of hot chocolate were helpful in treating chest ailments and that smaller amounts could help stomach disorders. When chocolate was introduced to the French in the 17th century, it was reportedly used "to fight against fits of anger and bad moods", which may be attributed to chocolate's phenylethylamine content. Today, hot chocolate is consumed for pleasure rather than medicinally, but new research suggests that there may be other health benefits attributed to the drink.
