Antioxidant and Neuroprotective Potential of Ashwagandha In Aluminum-Induced Toxicity

Indian ginseng is also known as Indian winter cherry, Ashwagandha, or the herb Vitania sluggard (Withania somnifera).The raw material used in medicine is the root, and the name "Ashwagandha" is derived from the word "ashwa", meaning horse.It is believed that after consuming the root, one gains powers similar to that of a horse.The second part of the name "gandha," means fragrance and refers to the characteristic smell of the fresh root of the plant.Since ancient times, it has been traditionally used in Ayurvedic medicine as a substance that strengthens the nervous system.It contains potent antioxidant compounds like flavonoids and phenolic compounds that help fight free radicals, reduce oxidative damage, and support the body's natural antioxidant enzyme activity.Many toxicological studies have proved the safety and edible nature of Ashwagandha 11 .Ashwagandha is known to have many valuable and protective properties like antioxidant, antibacterial, adaptogen.Some prefer to have it as liver tonic, aphrodisiac, and anti-inflammatory drug 12 .It is also proved that Ashwagandha has many potent pharmacological role which include restoration of physiological specifications, improvement of mental function in old age as well as recovery from neurodegenerative disorders 13 .Alkaloids, steroidal lactones, saponins, and withanolides sitoindosides VII-X and withaferin A are the biological active component of Ashwagandha.Clinical studies conducted in various conditions suggest that ABSTRACT Introduction : Aluminium is the most abundant metal and the third most common element in the Earth's crust, following oxygen and silicon.Exposure to aluminium is associated with oxidative damage, primarily due to its ability to disrupt redox balance, generate reactive oxygen species, and impair antioxidant defense mechanisms.This study was aimed to find the potential role of ashwagandha on aluminium induced brain toxicity.Methods: In the present study rats were grouped into 4 groups of 6 rats in each.Brain tissue was removed and processed for biochemical and histopathological analysis.Results: In the present study, administration of aluminium to rats resulted in a significant decrease in tissue GSH levels and a corresponding increase in MDA levels in the aluminium-treated group compared to the normal control.. Treatment with Ashwagandha showed a significant increase in GSH level and decrease in MDA level.Photomicrographic sections of the Brain in Ashwagandha-treated rats showed normla neuronal Count and exposure to Aluminium has caused significant reduction in the neuronal count.Experimental group pretreated with ashwagandha showed a visible increase in neuronal count in different regions of the rat brain.Conclusion: The results revealed that oral administration of aluminium induced adverse oxidative effects in the exposed animals, while treatment with Ashwagandha markedly reduced the extent of aluminium chloride-induced brain injury.
