The old hen's tonic benefits are more effective. Many chronically ill and thin people use it to replenish themselves, especially those who suffer from severe cold and wind and are not tolerated. The old hen can not only replenish qi and blood, but also expel wind. The term (referred to hens who have not laid eggs) is much better. According to the habit of most people, they like to eat fresh chicken, but don't like old hens with thick meat and hard bones. But judging from the effect of expelling wind and nourishing blood, the older the hen, the better the effect. Because the old hen has a lot of meat and calcium, it is most suitable for anemia patients, pregnant women, mothers and people with poor digestion.
