More Than a Pretty Greenhouse- Kew Gardens research into herbal remedies

Scientists at Kew Garden's Jodrell Labs are looking for the active compounds in traditional British folk remedies. The first to show real promise is figwort, from Northern Ireland and Norfolk- it appears to have promise in treating leg wounds and diabetes. They are looking at all kinds of plants common in Britain, many with names that reflect their supposed powers: The herb lovage, for example, won its name because of its reputation as an aphrodisiac. "Sage is a herb that has been connected with wisdom down the ages, and now for the first time we can see whether it really helps with cognitive ability, or memory" We don't know which to buy first. ::ObserverOther plants with (claimed) medicinal powers
