A staple of French cooks, thyme reveals its flavor best in dishes that are cooked slowly, like soups or stews. Current research shows that thyme leaves, long valued for their strong antiseptic properties, can help treat stomach ulcers. Thyme tea makes an excellent remedy for sore throats and hangovers: Lightly crush 5 fresh or dried leaves. Place in a cup and fill with water cooled to just below boiling. Cover cup and leave to infuse for 5 minutes. Remove leaves and drink.
