A systematic review of Korean medicine treatment for chronic urticaria, and a study examining the mechanism of Gamisoyo-san in urticaria patients, have been reported.

In chronic urticaria continuing more than six weeks, no cause is found in most cases. That no cause was found does not mean it cannot be treated.

If your lips or eyes swell, you become breathless, or there is a feeling of the throat tightening, go straight to an emergency department. In this case delay is dangerous.
