Benefits of winter vegetables:

Large white radish is an indispensable dish for many families to keep healthy in winter. Chinese medicine believes that radish has the functions of promoting digestion and resolving phlegm, relieving asthma and clearing away heat, regulating qi, reducing swelling and removing silt. Most children have symptoms of upper respiratory tract infection such as dry throat, sore throat, repeated cough and difficulty spitting when they catch a cold. Eating more crisp, fragrant and tender radish can not only stimulate appetite and help digestion, but also moisten throat, eliminate phlegm and smooth qi, effectively preventing colds.
