17th century book written by King Charles II's personal physician, Dr. William Sermon reveals that ancient royals used a loaf of bread to cure earache.
The book, titled 'A Friend To The Sick, or The Honest Englishman's Preservation', explained that taking a loaf made with one part of caraway seeds, cutting it through the middle and applying it to the ears was an easy cure for earaches.
The book, which sheds light on some old home remedies, also claimed that rubbing watercress into the gums was an excellent cure for toothache, the Daily Express reported.
Sermon also advised in the book, which is expected to fetch around 500 pounds when it goes under the hammer, that tobacco ash is of excellent use to cleanse the teeth and to make them white.
The book was found during a house clearance in Derbyshire.
