桂枝龙骨牡蛎汤 治失精家少腹弦急，阴头寒，目眩发落。脉极虚芤迟，为清谷亡血失

桂枝汤原方加龙骨、牡蛎各三两，水七升，煮三升，分三服。
桂枝去芍加蜀漆，龙骨牡蛎救逆汤，火迫（古人治伤寒有火熨、水攻之法。）心经阳欲
越，肢寒汗出必惊狂，（按亡阳惊狂，必有肢寒汗出见证。）神明散乱行将脱，固脱安神此剂
彰。（火迫心经之阳，非酸收可安，故去芍药，而用龙、牡镇摄，借桂枝、蜀漆疾趋阳位，
以救猝然散乱之神明，故先煮蜀漆，使其飞腾，劫去阳分之痰，并赖其急性，引领龙、牡，
从阳镇惊固脱。方寸无主，难缓须臾，故曰“救逆”。徐灵胎《伤寒论类方》曰∶此与少阴
汗出之亡阳迥别∶盖少阴之亡阳，乃亡阴中之阳，故用四逆辈，回其阳于肾中；今乃火逼汗，
亡其阳中之阳，故用安神之品，镇其阳于心中。各有至理，不可易也。”）桂甘龙牡汤同意，
火逆烧针烦躁良。（镇其阴气，散其火邪，上下同治。前方惊狂，治重在心，故用蜀漆；此
无惊狂，故蜀漆不用。其证大段相同。）《金匮》桂龙牡蛎汤，失精亡血梦交尝，脉微迟芤阴
阳弱，镇摄精神使敛藏。（此心肾不交，精伤气竭，神不敛藏之证。桂枝汤外感用之能祛邪
和营卫，内伤用之能补虚调阴阳，加龙骨、牡蛎，收敛其浮越之神，固摄其散亡之精。）
Treats irritability and restlessness caused by fire-induced reversal followed by purgation, and subsequently by burning needle therapy.
Guizhi (Cinnamon Twig), Gancao (Licorice Root) (each 1 liang), Longgu (Fossilized Bones), Muli (Oyster Shell) (each 2 liang). Add five sheng of water, boil to obtain two and a half sheng, remove the dregs, take eight he warm, three times daily.
Guizhi Longgu Muli Tang (Cinnamon Twig, Dragon Bone, and Oyster Shell Decoction): Treats individuals prone to seminal emission who present with tightness and urgency in the lower abdomen, coldness in the genital region, vertigo, and hair loss. The pulse is extremely deficient, Kou (hollow like a scallion stem), and slow, indicating cold yang, undigested food in stool, blood loss, or seminal emission; if the pulse presents various characteristics of Kou, moving, faint, and tight, men suffer from seminal emission, and women experience nocturnal emissions with sexual dreams.
This formula consists of the original Guizhi Tang (Cinnamon Twig Decoction) plus Longgu (Fossilized Bones) and Muli (Oyster Shell), each 3 liang. Add seven sheng of water, boil to obtain three sheng, divide into three doses.
Guizhi Qu Shaoyao Jia Shuqi Longgu Muli Jiuni Tang (Cinnamon Twig Decoction without Peony, plus Chinese Herbaceous Aristolochia Root, Dragon Bone, and Oyster Shell Decoction for Saving Reversal): Caused by fire therapy forcing (ancient methods for treating cold damage included hot compresses and water attacks), leading to the departure of Yang qi from the Heart channel, manifesting as cold limbs, sweating, and inevitably fright and mania. (Note: Fright and mania due to Yang collapse must be accompanied by cold limbs and sweating.) When Shen Ming (Spirit and Intellect) is scattered and on the verge of dissipation, this formula consolidates collapse and calms the spirit. (Fire forcing the Yang of the Heart channel cannot be pacified by sour astringents alone; thus, Shaoyao (Peony Root) is removed, and Longgu (Fossilized Bones) and Muli (Oyster Shell) are used to anchor and subdue. Guizhi (Cinnamon Twig) and Shuqi (Chinese Herbaceous Aristolochia Root) are employed to swiftly ascend to the Yang position to rescue the suddenly scattered Shen Ming (Spirit and Intellect); therefore, Shuqi (Chinese Herbaceous Aristolochia Root) is decocted first to allow its properties to rise vigorously, dispel phlegm in the Yang aspect, and utilize its acrid and rapid nature to guide Longgu (Fossilized Bones) and Muli (Oyster Shell) to calm fright and consolidate collapse from the Yang position. With no master within the heart, relief cannot be delayed even for an instant, hence it is called "Saving Reversal". Xu Lingtai stated in *Lei Fang* (Classification of Formulas): "This is distinctly different from Yang collapse with sweating in Shaoyin disease: Shaoyin Yang collapse involves the loss of Yin-contained Yang, so Sini Tang (Counterflow Cold Decoction) and similar formulas are used to return Yang to the Kidney; here, fire forces sweating, causing the loss of Yang-contained Yang, so spirit-calming agents are used to anchor Yang in the Heart. Both have profound rationale and should not be interchanged.") This shares the same principle as Guigan Longmu Tang (Guizhi, Licorice, Dragon Bone, and Oyster Shell Decoction) and is effective for irritability caused by fire reversal and burning needles. (It anchors Yin qi and disperses fire pathogens, treating both upper and lower. The previous formula targets fright and mania, focusing treatment on the Heart, thus using Shuqi (Chinese Herbaceous Aristolochia Root); this formula lacks fright and mania, so Shuqi (Chinese Herbaceous Aristolochia Root) is omitted. The syndromes are largely similar.) The Guizhi Longgu Muli Tang (Cinnamon Twig, Dragon Bone, and Oyster Shell Decoction) in *Jinkui Yaolue* (Essential Prescriptions of the Golden Cabinet) is often used for seminal emission, blood loss, and nocturnal emissions with sexual dreams. A faint, slow, and Kou (hollow) pulse indicates deficiency of Yin and Yang; this formula anchors the spirit and promotes storage and consolidation. (This is a syndrome of Heart-Kidney non-interaction, injury to essence and exhaustion of Qi, where the Spirit fails to consolidate. When used for external contraction, Guizhi Tang (Cinnamon Twig Decoction) expels pathogens and harmonizes Ying and Wei; when used for internal injury, it tonifies deficiency and regulates Yin and Yang. Adding Longgu (Fossilized Bones) and Muli (Oyster Shell) converges floating Shen Ming (Spirit and Intellect) and secures dissipating Jing (Essence).)
