"I see."

Wang Jianshe suddenly realized, "I said I've been taking it for so long, but there's no effect at all, and my constipation symptoms haven't improved."

"This is what Chinese medicine calls the wrong medicine for the wrong condition."

Yun Heng said, "The instructions for Niuhuang Qingwei Pills say it's used for excessive heart and stomach fire, dizziness, mouth and tongue sores, swollen and painful gums, sore throat, constipation, and dark urine. Even though they may all be constipation, the causes may not be the same. Taking a pill based solely on a single symptom is definitely not the right approach."

This is also the main reason why Yun Heng talked so much about traditional Chinese medicine today.

Medicines are generally divided into prescription drugs and over-the-counter drugs. Prescription drugs can only be prescribed by doctors and are not available in pharmacies outside, while over-the-counter drugs can be purchased in pharmacies.

Nowadays, many people take medicine, especially some over-the-counter medicines, according to the instructions, and also according to the habit of taking Western medicine. The instructions of Western medicine generally only need to include certain symptoms, such as fever, runny nose, and headache. These may not all be included, but only one or two, and some people can take the medicine according to the instructions.

However, it is difficult to treat the symptoms effectively if Chinese patent medicines and pure Chinese herbal preparations are only used according to one or two symptoms, and it is also easy to make mistakes. Sometimes, when the patient has deficiency symptoms, laxatives are used; sometimes, when the patient has excess symptoms, tonics are used. Not only will the medicines have no effect, but they may also aggravate the symptoms.

Chinese medicine doctors are very cautious when making a diagnosis, combining pulse and symptoms, and seeking confirmation from all aspects. Just like Yun Heng said when Tang Hua was studying, they are like judges, unraveling the disease layer by layer to identify the cause and then prescribe the right medicine. If a small instruction manual could tell the essence of it, then Chinese medicine would not be so difficult to learn, and Chinese medicine masters would not be so rare.

How can the disease be cured if the medicine is not suitable for the disease?
