Recently, some patients have asked what is wrong with the bitter mouth in the morning, and it is as bitter as yellow, and there are many similar patients in the outpatient clinic, and they don’t even know what department to register, and they have done ultrasound of liver, gallbladder and spleen, and checked the liver and gallbladder function are normal. In fact, morning bitterness in the mouth can often be treated with good results from Chinese medicine. The morning rise is the time when the Qi of Shaoyang is more vigorous, the Qi of Shaoyang can be called the Qi of liver and gallbladder, Shaoyang phase fire, also known as bile fire, and the same source as the ruling fire, the beginning of the ruling fire, generally hidden in the water and fire of the residence of the kidney, bitter taste into the heart, heart for the fire organs. If the spleen and stomach are weak, then the earth is weak and cannot subdue the fire, and the Yin fire multiplies the earth, and the phase fire does not descend easily, thus having the symptom of bitter mouth in the morning. The general public choose Xiao Chai Hu granules and Gentian Diarrhea Liver Pill to treat, can often receive certain results, but the cure is not the root cause, after stopping the medicine again easy to repeat. In the author’s opinion, there is nothing wrong with the general direction of treating this kind of mouth bitterness from the liver, gallbladder, spleen and stomach. In clinical practice, the prescriptions used are often no more than Chai Hu class prescriptions, Si Jun class prescriptions, Sheng Yang Dispersing Fire class prescriptions and Lian Pu Drink class prescriptions. However, all medicines should be used to avoid excessive bitterness and coldness, and it is only proper to take care of the spleen and stomach, and to dredge the liver and nourish it. In terms of diet, I advise patients with such symptoms to avoid cold and greasy products, especially frozen and cold products for dinner, which will damage the spleen and stomach even more, so try to have a light dinner.
