What method of prevention and treatment from the past was the most effective?
Many of the practices used during the Black Death are viewed as unsanitary and hazardous in modern times. However, direct treatment to the body was not the only technique they attempted. There were other practices to help prevent the spread of the disease, such as quarantine. (Roos, 2020)
Previously, in former times, the utmost effective method of plague prevention and treatment was the practice of quarantine. Other efficacious techniques were sitting near fires, as the bacterium is heat-killed (The Black Death Prevention Methods, N.D.), and boil lancing, a procedure in which an incision is made in the buboe to release the contaminated pus. Boil lancing was introduced to treat the bubonic plague in 1361, during the second plague outbreak. (BBC History Magazine & BBC History Revealed, 2021)
