After beginning of spring, the yang will rise, and the "liver-qi" in our body will flourish with the temperature rising. The "liver qi" in human body will reach its peak around Tomb-Sweeping Day. If the "liver qi" is too strong at this time, it is easy to damage the spleen and stomach. Chinese medicine believes that the liver is among the "five flavors" and corresponds to "acid". Before and after Tomb-Sweeping Day, if you eat more acidic food, it will be detrimental to the function of the spleen and stomach, thus affecting the digestion and absorption of the spleen and stomach. Therefore, in the daily diet, we should eat less acidic foods such as mutton, dog meat, marine fish, shrimps and crabs.
Because there is much rain and high humidity in Tomb-Sweeping Day, we should pay attention to choose some foods that warm the stomach and remove dampness, such as Chinese cabbage, radish and taro.
The "hair growth substance" mentioned in Chinese medicine refers to the product of expelling wind, producing phlegm, sending poison and helping fire to eliminate evil. Hair diseases are generally manifested as fever, sores, excessive internal heat, wind, phlegm, flatulence, constipation, diarrhea and chronic diseases. At this time, chronic diseases such as asthma are easy to recur. Therefore, citizens suffering from chronic diseases should pay attention to avoid eating "hair" at this time, such as seafood, pickles, bamboo shoots, mutton and cocks with high protein content.
