A reflection on a passage from Huáng Yuányù's Heart Source of the Four Sages, centered on one image: underground springs stay warm through winter, making spring possible from within, not from external sunlight. Huáng applies this to fertility and blood physiology, arguing that life, whether seasonal or bodily, depends on preserved internal warmth rather than outside stimulation. Living on a farm makes the medicine viscerally legible.
Considering the illness that is related to this formula, I could see Zhang and Lu’s words are authenticated. Looking back I can see that for the first dose, Da Qing Long Tang was the correct formula. Yet even though the formula pattern was correct, death was not avoided. It is not that the herbs in this formula are deadly. It was the application of them that was deadly. This was a serious disease that required strong herbs. But I did not observe the rules for safety vs. danger. Ma Huang is able to cause a person to sweat but too much sweating plunders the Yang. I gave 6 qian of Ma Huang combined with Gui Zhi. How was this going to guard against a big sweat? Moreover, in regard to the method after taking the herbs, the Shang Han Lun clearly warns that “If there is recovery, sweating once again will damage the Yang.” I did not tell them that they should not repeat the herbs if there was sweating. This lead to a situation in which they gave herbs after the sweating and the Yang was damaged leading to death. This formula should not be taken again with these dosages because it can damage the Yang. One must give advanced notice about the conditions and safety measures for after taking these herbs. One should prepare a Si Ni type formula beforehand and give this to the patient, being prepared for any contingency because cold limbs with a pulse on the verge of expiring can be cured. This failure to carry out the above plan caused a gross error and was due to my own barbaric ignorance.
This post introduces a new translation project focused on the Qing-dynasty physician Huáng Yuányù, whose work offers a strikingly coherent vision of physiology rooted in the unity of qi. Rather than proposing a formal doctrine, Huáng consistently explains health and disease through the smooth—or disrupted—circulation of a single qi, governed by ascent and descent around the spleen–stomach axis. The modern phrase “one qi flowing in an unbroken cycle” is a later synthesis of this core insight. Drawing from Huáng’s life, influences, and clinical thinking, the article explores how illness arises when qi cannot rise or descend freely, and how treatment aims not at isolated symptoms but at restoring the continuity of movement itself. Huáng distilled this perspective in his seminal work Sì Shèng Xīn Yuán, demonstrating how simple formulas, precisely applied, can produce profound results. For the translator, Huáng Yuányù’s thinking resonates deeply with a contemporary, systems-based understanding of medicine. This first translated excerpt offers a glimpse into a classical voice that feels unexpectedly current—and sets the stage for further exploration of his work.
