Since ancient times, medicinal plants have been used to treat a variety of illnesses, and their potential for neuroprotection is receiving more and more attention. The bioactive substances called phytochemicals, which are present in these plants, have shown great promise in the treatment of neurodegenerative illnesses such as Parkinson's, Alzheimer's, and stroke-related brain damage. Through a variety of methods, such as antioxidant activity, anti-inflammatory qualities, modulation of neurotrophic factors, and regulation of apoptotic pathways, these substances-which include alkaloids, flavonoids, terpenoids, and phenolic acids-execute neuroprotective effects. Plant-derived bioactive compounds are appealing candidates for neuroprotective therapeutics because of recent studies that have demonstrated their capacity to reduce oxidative stress, improve mitochondrial function, and increase neuronal survival. Furthermore, a number of therapeutic herbs, including Withania somnifera, Panax ginseng, Curcuma longa, and Ginkgo biloba, have demonstrated promise in preclinical research. The term "nootropic" refers to pharmaceuticals or dietary supplements that improve brain function. There are several pharmaceutical products on the market that have been used for their neuroprotective qualities by changing the ratio of specific molecules (Neurotransmitters) that are involved in brain function. In cases of chronic brain impairment, such as stroke, poor brain blood flow, dementia, and pseudo dementia, certain medications improve cerebral blood flow, the metabolic rate of cerebral oxygen consumption, and the metabolic rate of cerebral glucose. Because of their active phytochemical components, a number of medications made from medicinal herbs have demonstrated memory-enhancing qualities.
