Are we enduring the worst hay fever season? When was the disgustingly-named “summer catarrh” first identified as a medical condition? And what can we safely plant in the garden without setting off our symptoms? GP Navjoyt Ladher and immunologist Danny Altmann join James Gallagher in the park to talk causes and treatments, and to find out how close we are to having a cure.
