history.  Recent studies have, however, found it to have good wash and light fastness.  The main uses of the tree, other than for its timber, are culinary and medicinal.  Its sap is used to flavour white wines such as the traditional Retsina, and ‘pine honey’ is made by a sap-sucking insect.  The resin is also used in traditional Turkish medicine, mixed with honey for treating stomach and intestinal wounds, and as a mouth and tooth cleaner.  In ‘oil of turpentine’, it is antiseptic and astringent, and is used as a rub in steam baths.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp
