Qufeng oil When XDD has a stomachache (commonly known as intake wind in Malaysia), you can wipe it. It is said that it can drive away the wind in the stomach.

There is also a stuffy nose when you have a cold. You can take a little and put it under your nose, because it tastes choking and can clear it up.

When you have a headache, you can also apply some to your temples to relieve it.

You can also put it under your nose when you are carsick, which can refresh you, and so on. It acts a bit like green oil essence. As far as I know, Malaysians use XD this way.
