Antioxidant Properties

Sage is a potent antioxidant that can help neutralize free radicals and reduce oxidative stress in the body. According to a study published in the Journal of Agricultural and Food Chemistry, sage has the highest antioxidant capacity among all culinary herbs tested [1].

Neutralizing Free Radicals

Free radicals are unstable molecules that can cause damage to cells and contribute to the development of chronic diseases such as cancer, heart disease, and Alzheimer’s disease. The antioxidants in sage can help neutralize these free radicals and prevent them from causing harm [2].

Reducing Oxidative Stress

Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. This can lead to cellular damage and contribute to the development of chronic diseases. The antioxidants in sage can help reduce oxidative stress and protect cells from damage [3].

Sage contains several compounds that contribute to its antioxidant properties, including rosmarinic acid, carnosic acid, and salvianolic acid [4]. These compounds have been shown to have potent antioxidant activity and can help protect cells from damage caused by free radicals.

Cognitive Function Enhancement

Sage has been traditionally used as a brain-enhancing tonic, and recent studies have confirmed its potential cognitive-enhancing effects. The active compounds in sage, such as rosmarinic acid and carnosic acid, have been shown to enhance cognitive activity and protect against neurodegenerative disease.

Memory Improvement

Sage has been found to improve memory function in both healthy individuals and those with cognitive impairment. A study published in the Journal of Psychopharmacology found that a single dose of Salvia officinalis (sage) improved memory recall in healthy adults. Another study, published in the Journal of Clinical Pharmacy and Therapeutics, found that sage extract improved cognitive function and memory in patients with mild to moderate Alzheimer’s disease [5].

Neuroprotection

Sage has also been found to have neuroprotective effects. The rosmarinic acid in sage has been shown to protect against oxidative stress and inflammation, both of which can contribute to neurodegenerative diseases such as Alzheimer’s and Parkinson’s. In addition, sage has been found to protect against beta-amyloid-induced neurotoxicity, which is a hallmark of Alzheimer’s disease [6].

Digestive Health Benefits
