三仙丹提毒化腐，性颇和平，不独脓毒未清恶腐不脱者赖以化毒去腐，即至脓水净尽，
新肌盎然，亦可稍稍用之，即以生肌收口。但金石之性，藉炉火升炼而成，功最捷而吸力亦
富，全在研之极细，掺之极匀。若扑药太重，即能作痛。恒有病家知是神丹，索药自掺，往
往不知分量，用之太多，反以贻害。又不容靳而不予，致贻吝惜之讥。乃为汇集中正和平之
品，俾与三仙并行不悖。既有提脓拔毒之效，复无多用当痛之虞。是亦无法之法，命名“集
仙”，以志其实。

Sanxian Dan (Three Immortals Powder) extracts pus, eliminates toxins, and resolves necrotic tissue. Its nature is quite mild. It is not only relied upon to resolve toxins and remove necrotic flesh when pus and toxins are not yet cleared and foul tissue has not detached, but even when the pus and water have completely drained and fresh muscle is abundant, it can be used sparingly to promote muscle growth and close the wound. However, since the minerals and metals in this preparation are refined through furnace fire, its action is swift and its adsorptive power is strong. The key lies in grinding it extremely fine and applying it evenly. If the powder is too coarse or applied too heavily, it will cause pain. It often happens that patients, knowing it to be a miraculous medicine, solicit the drug for self-application; frequently unaware of the dosage, they use too much, thereby causing harm. On the other hand, one cannot be so stingy as to withhold it, lest one incur criticism for miserliness. Therefore, I have compiled a mixture of moderate and mild ingredients to run parallel with Sanxian Dan without conflict. This provides the effect of extracting pus and drawing out toxins, while eliminating the fear of pain from excessive use. This is also a "method beyond method," named "Jixian" (Gathering Immortals), to record its practicality.
