Eli5: Why does soaking an infected wound or toe in hot water draw out pus? How does it work, and how practical is this practice?
In: Biology
It doesn’t necessarily. It’s a start, because heat improves circulation, and water can do some flushing. If it’s circulating water. A stagnant hot bowl of just water won’t actually draw out puss, it will actually just relax the infected tissue which might permit the pressure from the infection to release through the dissolving wound, if there’s actually a skin penetrating wound. Adding an anti-bacterial solvent to the hot water is more helpful. Salt, alcohol, sugar, there are also drawing salves that have herbal components that can have an enhancing effect on the heat and dissolving capabilities of the bath
If there’s no skin penetration to begin with, the infection will usually be lanced…..
This is not advice. Just answering your question.
Disclaimer: lancing should be performed by a professional, on a closed course, not attempted at home. 😉
