A long time ago, there was an old doctor with excellent medicine skills. He opened his medical office in his home with a few students as assistants. One time, he had to leave home for a couple of days, and before the old doctor left, he gave his students several drug packages in order for them to help out with the home patients. The old doctor did not return home on time, and the medicine he left for his students were running out, and there were still many patients to cure. In the backyard, however, there were some chopped and dried grasses used for boiling the water left, so the students administered them to the patients and told them that it was their teacher’s medicine. Magically, the patients who were suffering from spleen and stomach problems, coughing phlegm, or with sore throats and ulcers were cured from this medicine. These dried grasses were liquorice roots. Since then, liquorice roots have been widely used in Chinese medicine and healing.
