Arsenic is a highly toxic substance after all, and ginger is an ordinary food after all. Even if we eat ginger at night, there will be no such serious harm as eating arsenic. In fact, this is just an exaggerated experience that the ancients did not recommend that everyone eat ginger at night, which played a warning role. But "eating ginger arsenic at night" means that it is not appropriate to eat ginger at night, which is scientifically justified.
Theory from the perspective of traditional Chinese medicine:
From the perspective of traditional Chinese medicine, every day has yin and yang, that is, midnight is the dividing point. After midnight, the yang in nature and in the body will gradually rise until noon, when the yang is the most abundant and the temperature is the highest. After noon, the yang will decay until it reaches its lowest value at midnight.
Therefore, according to the theory of traditional Chinese medicine, ginger belongs to warm food, so it is necessary to eat as much ginger as possible from morning to noon, which is helpful for the growth of yang. Of course, eating ginger and ginseng in the morning is an exaggeration, which is not comparable to ginseng at all. Folk sayings only emphasize that morning is a very suitable time to eat ginger.
In addition, autumn is not suitable for eating ginger. This is mainly because the dry weather in autumn is easy to damage the lungs. If you eat spicy ginger again, it will aggravate the dryness in the body, damage the lungs more easily and accelerate the loss of water in the body. Therefore, it is not recommended that you eat more ginger in autumn. In winter, if the weather is always dry, it is not suitable for eating. So summer is the best time to eat ginger, so there is a saying that "eat radish in winter and eat ginger in summer".
