There are two kinds of oral ulcers.

First, accidental oral ulcer, don't worry, come quickly, go quickly (Scutellaria baicalensis Georgi, Rhizoma Coptidis, Atractylodis Macrocephalae, Radix Paeoniae Alba, Glycyrrhiza uralensis Fisch), grasp the amount, pay one to know the effect, pay two to pay half, and pay three to heal.

This situation (Atractylodes macrocephala, Scutellaria baicalensis, Atractylodes macrocephala, Zingiberis Rhizoma, Pinellia ternata, Glycyrrhiza uralensis, keel) can be cured in ten days.
