Neurodegenerative illnesses refer to the gradual, cumulative loss of neural activity.Neurological conditions are considered to be the second leading cause of mortality in the modern world and the two most prevalent ones are Parkinson's disease and Alzheimer's disease. The negative side effects of pharmaceutical use are a major global concern, despite the availability of many different treatments for therapy. We concentrated on different types of neurological problems and their influence on targets, in vitro, in vivo, and in silico methods toward neurological disorders, as well as the molecular approaches influencing the same, in the first half of the review. The bulk of the second half of the review focuses on the many categories of treatment possibilities, including natural and artificial. Nevertheless, herbal treatment solutions are piquing scholarly attention due to their anti-oxidative properties and accessibility. However, more quality investigations and innovations are undoubtedly needed to back up these conclusions.
Nigella sativa L., also known as black seed or black cumin, is a plant that has been used for centuries. In the past, this flowering plant was used as a food preservative and medicinal herb. A vital component of Nigella sativa, thymoquinone (TQ), plays a significant therapeutic role in the management of most diseases, including cancer, diabetes mellitus, hypertension, inflammation, gastrointestinal disorders, and neurodegenerative disorders. Neurodegenerative disorders are primarily caused by neurotransmitter hypoactivity, particularly insufficient serotonin activity. It has been discovered that many medicinal herbs and their active compounds have therapeutic value. Black cumin seeds have been used to heal ailments and its history traces back to ancient times such as ancient Babylonia. They can be used applied to alleviate edema, hair loss, and bruising, and consumd to treat stomach issues. It is one of the most feasible and effective medicinal plants. The use of nanoformulations based on Nigella sativa and TQ to treat neurodegenerative diseases (NDs) has yielded promising outcomes. Customized administration of nanoparticle (NP) systems and nanomedicine are two of the many options for drug delivery to the central nervous system (CNS) that are attracting increasing interest. Delivering a therapeutic and diagnostic substance to a particular location is the core target of NPs. Because of their distinct cell uptake and trafficking mechanisms, NPs can reduce the amount that accumulates in undesirable organs. The focus of the current review is on recent studies on the various neuroprotective properties of Nigella sativa as well as nanoformulations for NDs and the brain's uptake of NPs. The review summarizes the In vivo, In vitro, and In silico studies on the protective effects of black cumin against neurodegenerative disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
