Detailed explanation-1: -Amaranthus Spinosus L. Leaf juice is applied locally by the tribes of Malkangiri district of Orissa, India (Prusti and Behera, 2007a). The species is also being used as an antidote to snakebite by the Chatara block of district Sonebhadra, Uttar Pradesh, India (Singh et al., 2010).

Detailed explanation-2: -They are made by immunizing donor animals such as horses or sheep with snake venoms. These animals have robust immune systems, and produce powerful antibodies that can bind to snake venom components, enabling our own immune defences to eliminate these toxins.

Detailed explanation-3: -Antivenom is traditionally made by collecting venom from the relevant animal and injecting small amounts of it into a domestic animal. The antibodies that form are then collected from the domestic animal’s blood and purified. Versions are available for spider bites, snake bites, fish stings, and scorpion stings.

Detailed explanation-4: -When performed antibodies are directly injected into the body, it is known as artificial passive immunity. It provides the quick immune response. In case of snake bites, the injection which is given to the patients, contain performed antibodies against snake venom. This type of immunisation is passive immunisation.
