Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
This then became the beginning of scientific research on herbal remedies on humans, which has been modified and significantly changed from modern wound remedies. [1] The Greeks also acknowledged the importance of wound closure, and were the first to differentiate between acute and chronic wounds, calling them "fresh" and "non-healing ...
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
Tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [1]) is the closure or blockage (as of a wound or body cavity) by or as if by a tampon, especially to stop bleeding. [2] Tamponade is a useful method of stopping a hemorrhage .
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
A related parameter, duty cycle, is defined as the ratio of the ON time to the period (the time of a single ON-OFF cycle). In the terminology of electrical engineering , the process of altering this ratio to achieve an average amplitude, instead of altering the amplitude directly is called pulse-width modulation .

Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding. This technique induces localized tissue burning and damage, the zone of which is controlled by the frequency and power of the device.
