绍兴癸丑年，我在四明等待任职期间，有一位董姓书生，患神气不宁之症，睡觉时梦见身体飞扬，虽然身在床上，但神魂仿佛离体，惊悸多梦魇，通宵无法入睡，更换多位医生治疗均无效。我为他诊视后询问说：“医生们当作什么病来治？”董生说：“大家都认为是心病。”我说：“从脉象来看，是肝经受邪，并非心病。肝经因虚损，邪气乘袭。肝主藏魂。游荡的魂气发生变化，普通人肝不受邪，睡觉时魂气回归肝脏，神志安静从而能入睡。现在肝有邪气，魂气不能回归，所以睡觉时魂气飞扬好像离开身体一样。肝主怒，所以稍微发怒病情就会加重。”董生高兴地说：“以前从未听人说过这种理论。虽然还没服药，似乎感觉沉重之感已离体了。希望能求得药物治疗。”我说：“您先持有这个观点，与其他医生商议治疗方案，再慢慢验证。”过了十天，他又来了，说医生们遍查古今方书，没有与病症相符的，所以我开出这两个方子赠给他。服用一个月后，疾病全部消除。这个方子以真珠母为君药，龙齿为佐药。真珠母入肝经效果第一，因为龙齿与肝同类。龙齿和虎睛，现代人通常都作为镇心安神的药物，却不知道龙齿安魂，虎睛定魄，这是各自对应其所属类别的缘故。东方苍龙属木，归属于肝而藏魂；西方白虎属金，归属于肺而藏魄。龙善于变化，所以魂气游动而不安定；虎善于专静，所以魄气静止而能守舍。我认为治疗魄气不宁的，适宜用虎睛；治疗魂气飞扬的，适宜用龙齿。万物都有固有的规律而不失其常，这也在于人们能否通达理解罢了。

In the Gui-Chou year of the Shaoxing era, while waiting for an official appointment in Siming, I encountered a scholar named Dong who suffered from restlessness of Shen (Spirit). During sleep, he dreamed of flying; although his body remained in bed, his Hun and Po seemed detached from his body, accompanied by frequent palpitations and nightmares, resulting in insomnia throughout the night. Multiple physicians failed to cure him. After examining him, I asked, "How do other doctors treat this condition?" Dong replied, "They all consider it a Heart disease." I said, "Based on the pulse, this is a pathogen invading the Liver Meridian, not a Heart disease. The Liver Meridian is deficient, allowing pathogenic qi to invade. The Liver stores the Hun. When the wandering Hun undergoes transformation, in healthy individuals, the Liver does not accept pathogens; during sleep, the Hun returns to the Liver, the Shen becomes tranquil, and sleep ensues. Now, because there is pathogen in the Liver, the Hun cannot return, causing the Hun to scatter as if leaving the body during sleep. The Liver governs anger, so slight anger exacerbates the condition." Dong joyfully said, "I have never heard this explanation before. Although I haven't taken medicine yet, I feel the heaviness has already left my body. I wish to request medicinal treatment." I said, "Hold onto this theory and discuss the treatment formula with other physicians for verification." Ten days later, he returned, stating that physicians had consulted ancient and modern medical texts but found no matching formulas. Therefore, I prescribed these two formulas for him. After one month of administration, the illness was completely resolved. In this formula, Zhenzhu Mu serves as the Jun (Emperor) herb, assisted by Longchi. Zhenzhu Mu enters the Liver Meridian most effectively, as Longchi shares the same nature as the Liver. Longchi and Huqing are currently commonly used as heart-calming agents, but they actually function to calm the Hun and stabilize the Po, respectively, corresponding to their elemental associations. The Azure Dragon of the East belongs to Wood, corresponds to the Liver, and stores the Hun; the White Tiger of the West belongs to Metal, corresponds to the Lung, and stores the Po. The Dragon is capable of change, hence the Hun wanders and is unstable; the Tiger is capable of stillness, hence the Po remains stationary and secure. I believe that for treating instability of the Po, Huqing is appropriate; for treating scattering of the Hun, Longchi is appropriate. All things possess inherent principles that remain constant; this depends on human understanding.
