Plant-based nootropics are natural drugs that can improve cognitive abilities through various mechanisms. They enhance erythrocyte plasticity, inhibit aggregation, and possess antioxidant activity that protects brain tissue from neurotoxicity. They induce the synthesis of neuronal proteins, nucleic acids, and phospholipids for constructing and repairing neurohormonal membranes. The study provides brief descriptions of representative species, their chemical composition, uses, dosages, and contraindications. These plant nootropics have potential therapeutic benefits for treating cognitive disorders, but must be taken at optimal doses for extended periods, and their psychoactive properties are produced by a synergistic combination of several compounds.
