Summary
Researchers have demonstrated that the extract of Crocus sativus L. (saffron) can attenuate scopolamine-induced memory loss in rats. The study evaluated the efficacy of saffron at doses of 10 mg/kg, 15 mg/kg, and 20 mg/kg, observing significant improvements in memory and reductions in beta-amyloid plaques and neurofibrillary tangles in the brain. Saffron acts by inhibiting acetylcholinesterase (AChE), an enzyme that degrades the neurotransmitter acetylcholine, crucial for memory and learning. The results showed that saffron supplementation not only improved behavioral activity but also exhibited antioxidant and anti-inflammatory effects, suggesting a therapeutic potential against neurodegenerative diseases like Alzheimer’s. Despite the promising findings, the study was conducted in an animal model, which limits the generalization of the results to humans. The research highlights the relevance of saffron in traditional medicine and its potential application in brain health.
