According to the World Health Organization, the black mamba is one of the most dangerous snakes in Africa, and its venom contains a strong neurotoxin. Fortunately, however, antivenom for the black mamba snake already exists. Antivenom is a treatment that combats snakebite by extracting the toxins in the snake's venom and preparing them into a drug. It neutralizes the effects of the snake's venom and reduces or stops the damage it can cause.
