General information and properties:

Grapefruit essential oil has, like sweet orange essential oil, a high limonene content, which is why they share similar properties and indications regarding treatments of the digestive system. Limonene, as the major molecule, extracted from citrus peel, suppresses the production of pro-inflammatory factors (TNF alpha and nitric oxide). It has a cholagogue and choleretic action; It promotes hepatic drainage, stimulating the elimination of toxic substances. Limonene has a hypoglycemic effect (lowering blood glucose). Together with gamma-terpinene (also contained in orange, tangerine and lemon essence), limonene promotes a reduction in cholesterol and triglycerides. The beneficial action of its compounds at the hepatobiliary level and on fat and sugar levels in the blood gives it interesting properties in the prevention and improvement of metabolic problems such as: gastric hyperacidity, obesity, dyslipidemias, atherosclerosis, type 2 diabetes and overloaded liver, steatosis and biliary sludge. Grapefruit essential oil is commonly used, it facilitates digestion, it has hypolipidemic or lipolytic properties by stimulating the dissolution of fats due to its limonene content. Studies in the field of conditions in the bronchi, limonene, in addition to its anti-inflammatory and antioxidant properties (decrease in inflammatory cytokines and reactive oxygen species (ROS), inactivates the migration of white blood cells involved in hypersensitization and allergy reactions (polynuclear eosinophils). Grapefruit essential oil has a neurotropic action, by stimulating and increasing blood pressure, it makes the autonomic nervous system more receptive. It can be applied by diffusion to asepticize the environment. The studies carried out to evaluate the effect of Grapefruit oil in the control of overweight show the following conclusions: – Appetite suppressing properties (observed in rats). – Reduction of fat accumulation in subcutaneous adipocytes. – Its olfactory or topical application (massage) contributes, after several weeks, to a reduction in weight and waist circumference. The study concludes that Grapefruit essential oil can be included in a comprehensive approach to weight control and considered as a complementary aid to fight against problems related to obesity and against the accumulation of fat in the body.
