Is it bad to drink too much herbal tea?

Some people think that the temperature is too high in summer, and drinking herbal tea can protect the human body. Some parents are afraid of their children's heatstroke and give them herbal tea. In fact, even in hot summer, there are still a large number of people who are not suitable for drinking herbal tea.

1. People with yang deficiency constitution: Most modern people have yang deficiency constitution. Nowadays, many people sit in the office all day, facing the computer, the intensity of physical labor and outdoor activities is reduced, and the function of promoting yang is not exercised; In addition, the use of air conditioning makes the seasonal impact on human body in summer less obvious than before, which leads to the weakness of yang in the body with the rise of seasons. Therefore, many people's constitutions are in the transition to yang deficiency, and they can no longer bear a lot of stimulation from cold substances. There are often some office white-collar workers who are afraid of cold, cold limbs, pale face, loose stools and long urine. It is necessary to check whether they drink too much herbal tea.

2. Bitter summer people: Bitter summer people have weak spleen and stomach yang transport function, less food intake and relatively low resistance. Sweat is secreted more in summer, and Chinese medicine believes that sweat is the "yang liquid" of the human body. If you sweat too much, the yang will seep out with the sweat. If you take bitter cold herbal tea at this time, it will hurt the spleen and stomach, make the already weak spleen and stomach weaker and damage the healthy qi, which will not only aggravate the symptoms of bitter summer, but also cause many other diseases due to decreased immunity.

3. Menstrual and postpartum women: The warmth of meridians is the key to keep veins unblocked and prevent blood stasis. Women are extremely weak during menstruation and postpartum, and are particularly sensitive to the stimulation of cold and heat. If you drink herbal tea without restraint because of the hot weather, although you can feel the temporary coolness in your stomach, after these drugs are absorbed into the blood, the cold stimulation will slow the blood flow and even form congestion, causing dysmenorrhea, irregular menstruation, decreased menstrual flow, and even severe bleeding and amenorrhea.

4. children and the elderly: children are pure yang, so they are particularly prone to get angry. But drinking herbal tea is not a good way to prevent children from getting angry. Because the regulation function of spleen and stomach in children is still in the stage of establishment and perfection, the cold stimulation of foreign drugs can not be adjusted in time, but it will affect digestion and absorption because drugs directly act on the spleen and stomach, leading to abdominal pain and diarrhea. Due to the weakening of yang and the decline of organ function, the elderly will also have digestive system diseases and a series of symptoms of yang deficiency due to the stimulation of herbal tea.
