A more thorough explanation:

Effusio sanguinis is a Latin term that refers to the shedding of blood. It can also refer to the fine or penalty imposed for the shedding of blood. In the past, many lords of manors were granted the power to collect this fine.

For example, if someone was injured or killed in a fight, the person responsible would have to pay effusio sanguinis as a penalty. This was a way to discourage violence and maintain order in society.

Effusio sanguinis is also known as bloodwite or bloodwit. It was an important concept in medieval law and is still used in some legal systems today.
