On May 20, on this sweet, sweet day, a female patient with a face full of anxiety and painful expression, her mouth ulcer came back, and she cried when the pain was so bad. She thought whether she had a terminal disease, I carefully examined her mouth ulcers, ulcers are very deep there are three, the tip of the tongue, tongue left and right sides have, deep in the ulcer pain will be a little more powerful, which side of eating pain, so the patient will be painful to cry. Look at the tongue and pulse. The tongue is light red with tooth marks, white moss and weak pulse. The Chinese medicine practitioner identified the weakness of the spleen and stomach and the fire in the spleen and stomach, so I gave her a prescription of Chinese medicine to tonify the earth and fire, plus some herbs to promote the healing of the ulcer. On Sunday, May 24, the patient came for a follow-up consultation early in the morning and told me happily that after taking three doses of Chinese medicine, her mouth ulcer was no longer painful and she could eat with a big mouth.
