The venom of the Egyptian cobra (Naja haje) is a complex mixture of proteins and peptides that have a variety of effects on the human body. The main components of Egyptian cobra venom are neurotoxins and cytotoxins.
Neurotoxins are toxins that attack the nervous system. They can cause paralysis, respiratory failure, and death. Cytotoxins are toxins that damage cells. They can cause pain, swelling, and tissue death.
The venom of the Egyptian cobra is considered to be one of the most potent snake venoms in the world. The median lethal dose (LD50) of Egyptian cobra venom in mice is 0.12 mg/kg, meaning that it takes an average of 0.12 mg of venom per kilogram of body weight to kill half of the mice in a test population.
In comparison, the LD50 of inland taipan venom in mice is 0.025 mg/kg, making it the most venomous snake venom in the world. However, the Egyptian cobra is still a very dangerous snake, and its venom can be fatal to humans.
