This last in this 'Truth About' series tonight, this time they are looking at over-the-counter medicine which the people of Britain spend about £2.3 billion every year on. Chris van Tulleken questions if they are really worth the money and presents stunts aimed at revealing how some of the most popular medicines work. He investigates whether home remedies could have a similar effect on us and also seeks the truth behind long-held myths, including whether curry does cause indigestion and if honey and lemon really is just as effective as cough syrup.
