DETAILED DESCRIPTION OF THE INVENTION This invention provides a suitable composition for the treatment of halitosis, from now on referred to as the composition of the invention, which comprises a mixture of olive and parsley oils, in a ratio of olive oil parsley oil, by weight, comprised between 1 and 7. The olive is the fruit of the olive tree (Olea europea L. ) which belongs to the Oleaceae family. Apart from water, oil, carbohydrates and proteins, the olive contains numerous minerals, particularly calcium, several organic acids and vitamins A, B. sub. 1, B. sub. 2 and pp. Olive oil, extracted from the pulp of the olive, is constituted essentially by glycerides of oleic acid (70%) and of other acids in a lesser proportion, such as those of linoleic, palmitic, linolenic and arachidonic acid, and is usually employed in cookery. Parsley (Petroselinum sativum Hoffm. , Petroselinum crispum Mill. , or Carum petroselinum Benth & Hooker) belongs to the Umbelliferae family. Its seeds, leaves and roots are used. Its fragrance and taste seem to be due to an essence of complex and variable composition, which contains apiol, apioside and mirysticin. The main ingredients comprise volatile oils, fatty oils, flavonoids, vitamins A and C and minerals, especially iron, calcium, phosphorous and manganese. It is known for its diuretic, carminative, digestive, antispasmodic and nutritive effects, as well as for its stimulating effect upon the uterine muscle. It is widely used in cooking as well as in the treatment of urinary infections and stones, oedema, gastric disorders and anaemia. Parsley essential oil is employed in the elaboration of the composition object of the present invention. Nothing in the state of the art suggests that the combination of olive and parsley oils, in the proportions envisaged in this description, could be effective in the treatment of halitosis. The composition of the invention may also contain another or other vegetable oils, including, but without being limited to, the following: avocado oil, basil oil, custard apple tree oil, borage oil, camomile oil, hemp oil, safflower oil, cajeput tree oil, cedar oil, cypress oil, coconut oil, rapeseed oil, geranium oil, sunflower oil, pink evening primrose oil, jojoba oil, lanolin oil, lavender oil, lemon oil, linseed oil, peppermint oil, evening primrose oil, palm oil, rosewood oil, pineapple oil, primrose oil, castor oil, rosemary oil, sage oil, sandalwood oil, soy oil, tea tree oil, wheat germ oil, grape-seed oil and vetiver oil
