Seeds of Spanish Medicinal Sage: A Potent Source of Omega-3 Fatty Acids and Antioxidative Compounds

Spanish sage, scientifically designated as *Salvia hispanica*, represents a nutrient-dense botanical resource whose full potential remains underutilized in the regions where it grows indigenously, primarily due to insufficient awareness among local populations regarding its health-promoting properties. The seeds of this plant are distinguished by an exceptionally high lipid content—reaching up to 35% by weight—with a predominant proportion comprising polyunsaturated fatty acids, most notably α-linolenic acid (ALA), a critical member of the omega-3 fatty acid family. Extensive research confirms that consistent dietary intake of ALA contributes to a reduction in low-density lipoprotein (LDL, commonly referred to as "bad cholesterol") concentrations in blood serum, thereby mitigating the risk of developing cardiovascular diseases, including atherosclerosis and acute myocardial infarction. It is essential to emphasize that α-linolenic acid is classified as an exogenous compound, meaning the human body lacks the enzymatic capacity to synthesize it endogenously; thus, its regular consumption through dietary sources constitutes a vital component of preventive healthcare. An additional advantage of Spanish sage seeds lies in their rich content of natural antioxidants, such as p-coumaric acid and gallic acid, which effectively inhibit lipid peroxidation, thereby preventing rancidity and extending the shelf life of food products incorporating these ingredients.
