Shrubs and Trees

In the penultimate episode of his ethnobotanical guide to the medicinal property of plants, James Wong uses trees and shrubs to tackle minor everyday complaints. He shows one shaving rash sufferer how to growwitch hazel and turn it into a cooling gel, and offers three sinusitis sufferers some relief with a fragrant eucalyptus rub that takes just moments to make. He meets expert growers and turns St John's Wort into a skin balm for cuts and wounds, and creates a delicious looking frozen granita from willow bark to help provide pain relief.
