Black-bone chicken soup has the functions of nourishing yin and tonifying kidney, nourishing blood and replenishing essence, benefiting liver and clearing heat, and tonifying deficiency. It can regulate human immune function and resist aging. I have enjoyed the title of "medicated chicken" since I was old, but eating more can produce phlegm and help fire, generate heat and dispel wind, so body fat and evil spirits are rampant. Those with unclear pathogenic factors and severe skin diseases should eat less or avoid eating, and those with severe exogenous diseases should not eat. At the same time, they should also avoid spicy and greasy food, alcohol and tobacco.

Old hen soup is rich in nutrition and has the effect of tonifying deficiency. Drinking more chicken soup in winter will help to improve your immunity and keep the flu virus out. For those patients who have been captured by the flu virus, it will help to inhibit the inflammation and mucus production caused by the cold, thus alleviating the pain caused by the cold.
