Five taboos of drinking water without licorice, not long-term or large quantities of water with licorice to drink. Licorice has the effect of benefiting the qi and tonifying the middle, moisturizing the lungs and stopping coughs, clearing away heat and detoxification (removing heat and poisonous evils from the body), easing pain (relieving more urgent pain symptoms), and harmonizing medicinal properties. Licorice is used for treating spleen deficiency and tiredness, heart deficiency and palpitation, cough and asthma, carbuncle and gangrene (a kind of poisonous sores, acute suppurative disease occurring on the surface of the body, limbs and internal organs), laryngeal paralysis (pharyngeal redness, swelling, pain, or dryness, feeling of a foreign body, or itchy throat, difficulty in swallowing), medicinal and food poisoning, and pain in the epigastric region (the abdomen) and contracture of the limbs. Licorice should not be taken by those who have chest and abdominal distension and vomiting due to the prevalence of dampness. Licorice should not be used with seaweed, halberd, glycyrrhiza glabra and coriander. The effective dose of licorice in water is limited and generally cannot achieve a therapeutic effect; if there is any discomfort after drinking licorice in water, it is recommended to stop using it and seek medical attention in time.
