According to a systematic review published in Dementia and Geriatric Cognitive Disorders, sage (Salvia officinalis), a common culinary herb used for centuries in traditional medicine, showed promising benefits for Alzheimer’s disease.
The review highlighted a randomized, placebo-controlled clinical trial in which patients with mild to moderate Alzheimer’s disease who took 60 drops of sage extract daily for 4 months experienced significant improvements in cognitive function compared with those receiving a placebo.
Researchers reported benefits in memory, attention, learning ability, and overall cognitive performance. Importantly, the treatment was well tolerated, with no significant difference in adverse effects between the sage and placebo groups, making sage one of the most promising herbs investigated for Alzheimer’s disease at the time.
