“一剂知，二剂已”是中医经典著作《黄帝内经》中的一句名言，意思是在治疗疾病时，一剂药可以初见疗效，两剂药则可以病愈。这句话体现了中医治疗疾病追求速效的特点，同时也强调了治疗效果的明显和迅速。

“一剂知”指的是在服用第一剂药物之后，病人可以感受到病情的改善或者症状的缓解。这说明药物已经发挥了作用，病情得到了初步的控制或者改善。医生可以根据病人的反馈和病情变化，进一步调整治疗方案，以达到更好的治疗效果。

“二剂已”则是在服用第二剂药物之后，病情已经得到了完全的缓解或者治愈。这也说明了中医治疗疾病的速效性，以及中药对病情的快速控制作用。当然，并不是所有的疾病都可以在两剂药之内治愈，这只是一个形象的比喻，意在强调中医治疗的快速和有效。

在实际的临床应用中，“一剂知，二剂已”的治疗效果也因人而异，因病而异。对于一些急性、简单的疾病，可能确实可以在短时间内取得显著的治疗效果。但对于一些慢性、复杂的疾病，则需要更长时间的治疗和调理，才能达到治愈的效果。

不管如何推脱和推诿，真正的对症下药，效果总是很不错的。
"One dose knows, two doses have already" is a famous saying in the classic Chinese medicine work "Huangdi Neijing", which means that in the treatment of diseases, one dose of medicine can show initial efficacy, and two doses of medicine can cure the disease. This sentence reflects the characteristic of traditional Chinese medicine's pursuit of quick and effective treatment of diseases, while also emphasizing the obvious and rapid therapeutic effect.
"One dose knowledge" refers to the improvement of the patient's condition or relief of symptoms after taking the first dose of medication. This indicates that the medication has already taken effect and the condition has been initially controlled or improved. Doctors can further adjust treatment plans based on patient feedback and changes in the condition to achieve better treatment outcomes.
"Second dose already" means that after taking the second dose of medication, the condition has been completely relieved or cured. This also demonstrates the rapid effectiveness of traditional Chinese medicine in treating diseases, as well as the rapid control effect of traditional Chinese medicine on the condition. Of course, not all diseases can be cured in two doses of medicine, this is just a vivid metaphor aimed at emphasizing the fast and effective treatment of traditional Chinese medicine.
In practical clinical applications, the therapeutic effect of "one dose knowing, two doses already" also varies from person to person and from disease to disease. For some acute and simple diseases, significant therapeutic effects may indeed be achieved in a short period of time. But for some chronic and complex diseases, longer treatment and conditioning are required to achieve a curative effect.
No matter how you try to evade or shift the blame, the real solution is always very effective.
