“Cannabis sativa L. is an annual herbaceous dioecious plant which was first cultivated by agricultural human societies in Asia. Over the period of time, various parts of the plant like leaf, flower, and seed were used for recreational as well as therapeutic purposes. The main chemical components of Cannabis sativa are termed as cannabinoids, among them the key psychoactive constituent is Δ-9-tetrahydrocannabinol and cannabidiol (CBD) as active nonpsychotic constituent. Upon doing extensive literature review, it was found that cannabis has been widely studied for a number of disorders. Very recently, a pure CBD formulation, named Epidiolex, got a green flag from both United States Food and Drug Administration and Drug Enforcement Administration for 2 rare types of epilepsies. This laid a milestone in medical cannabis research.
This review intends to give a basic and extensive assessment, from past till present, of the ethnological, plant, chemical, pharmacological, and legal aspects of C. sativa. Further, this review contemplates the evidence the studies obtained of cannabis components on Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis, multiple sclerosis, emesis, epilepsy, chronic pain, and cancer as a cytotoxic agent as well as a palliative therapy. The assessment in this study was done by reviewing in extensive details from studies on historical importance, ethnopharmacological aspects, and legal grounds of C. sativa from extensive literature available on the scientific databases, with a vision for elevating further pharmaceutical research to investigate its total potential as a therapeutic agent.”

“This study has analyzed and reviewed the historical, botanical, chemical, ethnopharmacological, and legal aspects of C. sativa from the first human use to the present medical applications with an analysis of its multiple therapeutic applications for various diseased conditions in the contemporary scientific context. There is an abundance of support for its several medicative uses as well as a possible benefit in various diseased conditions. Extensive pharmacological examination is still needed to better understand the clinical significance and uses of active cannabinoids in the treatment and prevention of chronic diseases. Also, cannabis can be chemically standardized and under prescription can be used. With the majority of the United States currently legalizing medicinal cannabis and/or restricted CBD-only use, physicians need to be educated on the history and correct clinical use of cannabis, as a result of which patients can know more and more about possible treatment utilizing cannabis. Medical cannabis has shown to have clinical efficacy in our past, and in present, data show its therapeutic effects. Extensive research in the field of cannabis can be very fruitful for the medicine world.”
