A dissolvable foaming action hemostat may be compressed and may fully dissolve in a wound. The foaming action hemostat may use a liquid gel, a dried gel, a dry powder, a shape, or a solid “plug” like medium that may resemble a sponge or a sponge-like material and may include a foaming agent to spread therapeutic ingredients throughout the wound to control or stop bleeding. The foaming action hemostat also may introduce pharmaceuticals and/or other compounds into a wound to control/mitigate shock, calm the patient, administer antibiotics, administer anti-sepsis compounds, control infection, control sepsis, and/or mitigate pain. No harmful foreign matter is introduced in using a foaming action hemostat. This eliminates the need to surgically remove introduced foreign matter later. Use of a foaming action hemostat also may reduce the likelihood of trauma that sometimes occurs when foreign matter is left in place inside a wound.
