Kerosene
★☆☆☆☆
Kerosene and other should never be taken internally. It's extremelly toxic just like gas or diesel. Do not try this remedy. It's also highly flammable, so I wouldn't use it on the skin either (it is also toxic that way through absorption).
There are lots of remedies for colds and other ailments on this site that are safe to be tried, but not this one.
