eA 2025 preclinical study identified that diAcCA, a stabilized form of rosemary’s carnosic acid, improved memory and reduced Alzheimer’s-related brain plaques in mice.
Rosemary contains three primary compounds—carnosic acid, rosmarinic acid and 1,8-cineole—that function as antioxidants and anti-inflammatory agents.
The compound 1,8-cineole helps preserve acetylcholine, a neurotransmitter essential for memory and learning.
Most current evidence for rosemary’s cognitive benefits remains preclinical, with human studies showing mixed results depending on dosage.
Experts advise using rosemary in typical culinary amounts of 1-2 tablespoons fresh or 1-2 teaspoons dried per meal for safe, antioxidant-rich flavor.
A humble garnish long relegated to roasted potatoes and fish dishes is emerging as a subject of serious neurological research. In 2025, scientists developed a stabilized form of carnosic acid, a compound found in rosemary, called diAcCA. Preclinical studies at that time demonstrated that diAcCA improved memory in mice with Alzheimer’s disease while reducing amyloid plaques and tau tangles—the hallmark proteins of the condition. The finding arrives as pharmaceutical companies race to develop synthetic dementia drugs, and it reopens an ancient question: did traditional wisdom anticipate modern neuroscience?
