Vesicating cause chemical changes in the cells of exposed tissues almost immediately upon contact.

  • Mechanism of Vesicating and Blistering Many different agents can cause vesicating, which leads one to believe that an underlying mechanism must be common to all or any . Vesicating are often produced by heat, cold and ultra-violet light by friction by such well-known vesicants as cantharides, chloroform, mustard oil then on.
  • The action of chemical irritants, with which we are mostly concerned, is typically described as causing vascular spasm followed by excessive dilation of the underlying vessels. This dilation cause an excellent transudation of fluid. These cells are so devitalized that they rupture their intercellular bridges and a vesicle forms within the epidermis tissue The accompaniments of the formation of a vesicle are progressive weakening of the tissue and cellular degeneration.
