Pine nut oil is commonly used as a dietary oil, an appetite suppressant and an aromatherapy carrier oil. The oil is extracted from several different types of pine and primarily sold through online merchants and health food stores.
As a dietary oil, pine oil used is generally used in its natural state or heated over medium heat. For example, cooks include unadulterated pine nut oil in recipes such as Baba Ghanouj, pine nut oil pesto and raw tomato sauce. Recipes that call for pine nut oil to be heated over medium heat include Greek dip and Italian eggplant Caponata.
In 2006, a company named Lipid Nutrition reported that they gave 18 overweight women capsules containing either olive oil or pine nut oil. The women who consumed the pine oil stated that they felt less hungry and also showed higher levels of appetite-suppressing hormones in their blood, according to WebMD.
Natural health practitioners combine essentials oils such as lavender, peppermint or jasmine with pine nut oil to create aromatherapy and/or massage oils. Practitioners usually mix approximately 10 drops of the essential oil into 2 to 3 tablespoons of pine nut oil before applying to the skin. Twenty-five to 40 drops of the essential oil of choice are usually dropped into 2/3 cup of pine nut oil before burning for aromatherapy purposes.
