Phlegm is essentially water that has condensed. When the lungs and stomach are filled with fire, the water is scorched and congeals into phlegm, sharing the same origin as drinks. Drinks move in cold environments, so they are clear and not thick; phlegm, however, is cooked with fire, so it's sticky and hard to descend. Wang Yinjun formulated this recipe, using huangqin to clear invisible fire in the lungs, rhubarb to drain accumulated fire in the stomach—this treats phlegm by first clearing fire, addressing the root cause. However, since phlegm is fundamentally formed by water and moisture, mengshi is added to aggressively dry out the water. Where phlegm remains, qi is blocked and difficult to move, so agarwood is used to accelerate its descent. With mengshi and agarwood, the formula can swiftly attack old phlegm nests and stubborn, dirty areas, leaving little behind—this is why it's called "rolling phlegm." Make it into pills, take with ginger soup, lie on your back, and avoid eating for half a day. If there is congestion in the throat, it may be due to drug resistance, but the medicine will work on its own after a short while. Although the formula is quite potent, stubborn phlegm (1) often presents strange symptoms, and only this can treat them.

[Note] (1) Stubborn Phlegm: Refers to phlegm conditions that are stubborn and difficult to cure. For example, recurrent asthma attacks or prolonged, intractable phlegm-dampness. It is generally believed to be caused by stubborn phlegm lingering in the chest and diaphragm.

[Note] This formula originates from "Supplement to Danxi's Heart Method." It reduces fire and expels phlegm, treating severe heat and stubborn phlegm-related disorders.
