Loquat fruit dried in the sun and boiled in water is useful in treating coughs caused by lung heat. The effects of loquat are to clear the lungs and stop coughing (clearing lung heat and stopping coughing), and to lower the rebelliousness and stop vomiting (stopping the upward rush of stomach qi and stopping vomiting). Pei Pa Koa is bitter, cold and clear, and enters the lung meridian to lower and drain lung qi, clear the lungs and resolve phlegm (clearing lung heat and resolving phlegm) to stop coughing and asthma (stopping coughing and calming wheezing), and it can be used in conjunction with any wind-heat and dry-fire-induced coughing and asthma. However, if the cough is more serious or not clear what causes the cough, it is recommended that timely medical treatment, because the loquat dried and boiled to stop coughing effect is limited, the tea can not replace the use of drugs. Therefore, it is necessary to consult a doctor in time, so as not to delay the treatment and lead to worsening of the cough.
