Major Constituent and Mode of Action of Snake Venom and the Nullifying Activity of Both Synthetic and Herbal Remedies

The issues of snakebite have been a foremost socio-medical challenge disturbing numerous societies worldwide, most especially the Asian and African continents as a whole. The cure is still reliant on the use of antisera as the key means of management, which has been greatly limited. Hospitals in rural societies are substandard; treatment of snakebite is often handled by traditional doctors, either due to the cost or unavailability of synthetic antivenins. The venom of diverse snake classes has a unique constituent; this constituent could be altered by other dynamics, such as geography, age, seasonal disparities, and sex. Usually, snake venom consists of minute molecules, such as proteins, enzymes, inorganic cations, and peptides. However, snake bite envenomation is extremely related to mortality after systemic circulation of the venom; certain examinations reveal that snake venom’s constituent possesses inherent medicinal significance. The modus operandi of synthetic antivenin, as well as the anti-venom obtained from certain plant materials, and the major constituents found in snake venom (phospholipases A2, disintegrins, snake venom serine proteinases, alpha-neurotoxins, activity of fibrinolytic enzyme, and three-finger toxins) are discussed in detail in this review. Some selected theories that proposed the mechanism of action of compounds obtained from herbal sources to combat snakebite, such as enhancing/modifying action, protein precipitation, chelating properties, and enzyme deactivation, have been discussed.
