Over here we have camphor blocks, not sure if it's got another name, but they look like large menthol sweets.
I used to put 4 blocks in a jug of water, and wait for it to draw. Once the water's menthol, it's ready to drink.
Not the most pleasant thing to drink, but half a glass cleared my nausea in less than 5minutes.
It's 1 home remedy I swear by.
