GINGER's aromatic oils can relieve colds and flu and guard against rheumatism, says Dr Stephen Fulder, a biochemist and herbal specialist. In addition, the herb contains valuable medicinal compounds - such as gingerols and shogaols - that can be used to treat tummy upsets, stop nausea and vomiting, and improve the circulation.

Dr Fulder's new book, Ginger: The Ultimate Home Remedy, is published on 18 March by Souvenir Press Ltd, pounds 3.99, and will be available from bookshops.
