Vesicant

Vesicants are a class of chemical warfare agents that cause severe skin, eye and mucosal pain and damage. They are named for their ability to cause vesication, or blistering. These agents are also known as blister agents, or mustard gas.

History[edit | edit source]

The use of vesicants dates back to World War I, when they were first used on a large scale in warfare. The most well-known vesicant is mustard gas, which was used extensively during this time. Despite the 1925 Geneva Protocol prohibiting the use of chemical and biological weapons, vesicants have been used in several conflicts since, including the Iran-Iraq War.
