【茯苓神】
〔害〕功效专于利水，攻伐肾气。患有肾虚的病人，若出现小便自利或失禁、虚寒导致的遗精滑泄，以及阴液亏损导致的小便不利等情况，都不可随意服用。茯苓中带有赤色筋脉的部分，如果误服，会导致瞳孔缩小、黑睛出现斑点并伴有视力模糊甚至失明。茯苓与白蔹相恶（相互抑制药效），畏惧地榆、秦艽、鳖甲，忌食米醋及酸性食物、雄黄等。以马蔺为引经药。
〔利〕味甘淡而性平，治疗作用与茯苓相同。多用于入心经，能交通心肾从而安神、定志、开窍、益智，治疗心虚引起的惊悸、易怒和健忘。
〔修治〕捣碎成细末，放入水盆中搅拌，将浮在水面的杂质滤去，晒干后切制使用。必须在二月或八月采取，阴干。凡药用部分需去除中心木质部。若要宁心安神，可用辰砂拌制。
按《神农本草经》只记载了茯苓，《名医别录》开始区分茯神。茯神主守（固守心神），而茯苓主下利（通利水道）。白色茯苓入肺、膀胱的气分；红色茯苓入心、小肠的血分。
茯苓木，又名黄松节，即茯神中心的木质部分。松节散、乳香木瓜汤，可治疗各种筋脉挛急疼痛。乳香能舒展筋脉，木瓜能舒缓筋骨。
茯神心木，能宁心安神，治疗各种筋脉挛缩、中风口眼歪斜、心脏掣痛和健忘。
【猪心血】
〔害〕宰杀时因惊恐之气进入心脏，断气后归肝，均不可多吃。
〔利〕用作补心药的向导，取“以心归心，以血导血”之意。
〔修治〕用竹刀剖开猪心取出血液，与丹参等补心药物一起拌炒。
【琥珀】
〔害〕其性淡渗容易损伤阴液，凡是阴虚内热、火旺水亏的患者，不要服用。如果是血少导致小便不利的患者，服用后反而会导致干燥急促的痛苦。
〔利〕味甘平，入心、肝、肺、膀胱四经，能安神使鬼魅邪气不能侵犯。颜色赤红入血分，所以能消除瘀血、破除症瘕积聚、生肌长肉。能清肺利小便。甘淡之性上行，能使肺气下降，从而通调膀胱，所以能治疗五种淋证。又能消散瘀血，生成新血，去除目翳障蔽从而明目。经文说：脾气散布精微物质，上归于肺，通调水道，向下输送到膀胱。凡是淡渗的药物，都是先上行而后下降。琥珀是松脂深入地下年代久远形成的宝物，所以能通利闭塞以宁心定魂，凭借燥湿健脾土的功效。
〔修治〕松脂落入地下多年结成。投入水中也能结成。用手心摩擦发热后能吸附芥菜籽的为真品。用法是将柏子仁放入瓦锅中同煎半天，捣成粉末。
[Fuling Shen]
[Harm] Its efficacy is specialized in promoting urination and attacking Kidney Qi. For patients with Kidney deficiency, if there is spontaneous diuresis or incontinence, seminal emission and slipping due to deficiency-cold, or difficulty in urination due to Yin depletion, it should not be administered recklessly. The part of Fuling containing red fibers, if mistakenly taken, causes the pupils to shrink, black spots on the cornea, accompanied by blurred vision or blindness. Fuling is incompatible with Bai Lian (Bletillae Rhizoma), fears Di Yu (Sanguisorbae Radix), Qin Jiao (Gentianae Macrophyllae Radix), and Bie Jia (Trionycis Carapax), and is contraindicated with rice vinegar, acidic foods, Xiong Huang (Realgar), etc. Ma Lin (Iris lactea) serves as a guiding herb.
[Benefit] It tastes sweet and bland and is neutral in nature; its therapeutic action is similar to that of Fuling. It is mostly used to enter the Heart meridian, communicating between the Heart and Kidney to calm the mind, stabilize willpower, open the orifices, and enhance intelligence. It treats palpitations and fright due to Heart deficiency, irritability, and forgetfulness.
[Processing] Crush into fine powder, stir in a basin of water, filter off floating impurities, dry in the shade, and slice for use. It must be harvested in the second or eighth lunar month and dried in the shade. When used, the central woody core must be removed. To calm the mind, it can be mixed with Chen Sha (Cinnabar).
According to the *Shennong Bencao Jing*, only Fuling is mentioned; the *Mingyi Bielu* begins to distinguish Fushen. Fushen acts to guard (secure the Spirit), whereas Fuling acts to drain downward (promote urination). White Fuling enters the Qi level of the Lung and Bladder; red Fuling enters the Blood level of the Heart and Small Intestine.
Fuling Mu (the woody core of Fuling), also known as Huang Song Jie (Yellow Pine Joint), is the center of Fushen. Song Jie San (Pine Joint Powder) and Ruxiang Mugua Tang (Frankincense and Papaya Decoction) treat various tendon spasms and pain. Ruxiang (Boswelliae Resina) extends the tendons, and Mugua (Chaenomelis Fructus) soothes them.
The woody core of Fushen calms the Heart Spirit and treats various tendon spasms, hemiplegia with facial deviation, heart palpitations, and forgetfulness.
[Zhu Xin Xue]
[Harm] The qi of fright from slaughter enters the Heart, and upon death, the qi returns to the Liver; neither should be consumed in excess.
[Benefit] It is used as a guide for Heart-nourishing herbs, taking the meaning of "using the Heart to return to the Heart, and using blood to guide blood."
[Processing] Use a bamboo knife to剖 open the pig's Heart, extract the blood, and stir-fry it with Heart-nourishing herbs such as Danshen (Salviae Miltiorrhizae Radix).
[Hupo]
[Harm] Its bland and draining nature damages Yin. Patients with Yin deficiency and internal heat, or fire flaring with depleted water, should not take it. If a patient has scant blood causing difficulty in urination, taking it may instead cause suffering from dryness and urgency.
[Benefit] It tastes sweet and is neutral, entering the Heart, Liver, Lung, and Bladder meridians. It calms the mind so that evil spirits cannot invade. Its red color enters the Blood level, thus it can resolve blood stasis, break up masses and accumulations, and generate flesh. It clears the Lung and promotes urination. Its sweet and bland nature ascends first, allowing Lung Qi to descend, thereby unblocking the Bladder; hence, it treats the five types of strangury. It also disperses blood stasis, generates new blood, removes ocular nebulae, and brightens the eyes. The classics state: "The Spleen scatters essence, which ascends to the Lung; the Lung regulates water passages, transmitting them downward to the Bladder." All bland-draining herbs ascend first and then descend. Hupo is a treasure formed from pine resin buried in the earth for years; thus, it can unblock obstructions to calm the Heart and settle the Soul, relying on its function of drying dampness and strengthening the Spleen Earth.
[Processing] Pine resin buried in the earth for many years forms it. It can also form when submerged in water. Authenticity is verified if it adheres to mustard seeds after being warmed by rubbing with the palm of the hand. Preparation involves boiling Baizi Ren (Platycladi Semen) in a clay pot for half a day, then grinding into powder.
