黄杨叶主治妇女难产，可加入达生散中使用；又主治夏季暑热引发的疖肿，捣烂后外涂患处（出自《本草纲目》）。【产地】（李时珍说）：黄杨生长于山野之间，民间多栽种插植。其枝叶聚拢簇拥向上耸立，叶片像初生的槐芽一样，颜色青翠浓重，不开花，不结果，四季常青不凋落。它的生长特性是难以长高，俗话说是“每年长一寸，遇到闰年则退”，如今验证发现只是闰年不长而已。其木质坚硬细腻，制作梳子、挖印模最为优良。按段成式《酉阳杂俎》记载：世人重视黄杨木，是因为它“无火”。用水测试，沉入水中的就没有火性。凡是取用这种木材，必须在阴晦的夜晚，天空中无一星辰时才砍伐，这样木材就不会开裂。【味道】苦。【性质】平。

桃寄生（出自《本草纲目》）主治小儿中蛊毒，表现为腹部坚硬疼痛，面色青黄，消瘦枯槁如骨立状。取二两研为末，像喝茶一样冲服，每日服用四五次（无毒）。
柳寄生主治膈气刺痛，捣取汁液服用一杯（出自《本草纲目》）。【味道】苦。【性质】平。
脉是血的通道，是气血运行的先导，血在隧道中运行，气息随之相应。首先论述脉的来源：水流从源头分流，有合有分，起伏有道，各自井然有序。人身之血犹如水，血脉犹如河道。水道通畅则水源活跃，血脉通畅则气血运行。（所以《灵枢·决气篇》说）中焦摄取水谷精微，变化而成为赤色的血；壅遏营气，使其无处躲避，这就叫做脉。脉本是气血的先导，流行于经络之中，灌溉全身，昼夜循环，动而不息。大概脉就是人身一元的大气。血在经络中流行，就像水分流的样子，所以说脉是血的通道。脉实则血实，脉虚则血虚，要知道脉是气血的先兆。隧道即经脉，指其在血中精密隐蔽，自成一道。（《灵枢·营气篇》说）精专之气行于经隧，而脉则是指营气流行不息的道路。然而没有呼吸就不能流行，所以说气息随之相应。

*Trigonostemon yewifolius* leaf (Huangyang Ye) is indicated for difficult childbirth in women and can be used in *Dasheng San* (Da Sheng Powder). It also treats boils caused by summer heat; crush the leaves and apply externally (from *Bencao Gangmu*). [Origin] (Li Shizhen says): *Trigonostemon yewifolius* grows in mountains and wilds, and is often planted by households. Its branches and leaves cluster together and grow upward. The leaves resemble the sprouts of locust trees when they first emerge, are dark green, do not flower, and do not bear fruit. It remains evergreen throughout the four seasons. Its nature is difficult to grow tall; folklore says it "grows one inch per year and retreats in leap years." Current verification shows it simply does not grow in leap years. Its wood is hard and fine, making it excellent for carving combs and seals. According to Duan Chengshi's *Youyang Zazu*: People value *Trigonostemon yewifolius* because it has no "fire" property. When tested with water, those that sink have no fire nature. Whenever harvesting this wood, one must cut it on a dark, cloudy night with no stars visible, so that the wood will not crack. [Flavor] Bitter. [Nature] Neutral.

*Viscum coloratum* (Taoji Sheng) (from *Bencao Gangmu*) treats children suffering from gu poison, characterized by abdominal hardness and pain, yellowish-green complexion, and emaciation resembling skeletal remains. Take two liang, grind into powder, and administer like tea, four or five times daily (non-toxic).
*Viscum articulatum* (Liuji Sheng) treats stabbing pain in the diaphragm due to Qi stagnation; crush and take one cup of the juice (from *Bencao Gangmu*). [Flavor] Bitter. [Nature] Neutral.
The pulse is the vessel of blood, the precursor of Qi and blood. Blood flows through the tunnels, responding to breath. First, we discuss the origin of the pulse: just as water flows from its source, dividing and merging, rising and falling with order, so too does the pulse. The blood in the human body is like water, and the vessels are like riverbeds. If the waterway is unobstructed, the source is active; if the vessels are unobstructed, Qi and blood circulate. (Thus, the *Ling Shu · Jue Qi Pian* states:) The middle jiao extracts fluids, transforms them, and turns them red; this is called blood. Confining Ying Qi so it has nowhere to escape is called the pulse. The pulse is essentially the precursor of Qi and blood, circulating through the meridians, irrigating the whole body, cycling day and night without ceasing. Essentially, the pulse is the great Qi of the human body's unity. The circulation of blood within the meridians is like the flow of water in channels; therefore, it is said that the pulse is the vessel of blood. A full pulse indicates abundant blood; a deficient pulse indicates deficient blood. One must know that the pulse is the omen of Qi and blood. The tunnel refers to the meridians, indicating their precision and hidden nature within the blood, forming their own distinct path. (The *Ling Shu · Ying Qi Pian* states:) The refined and pure Qi travels through the meridian tunnels, and the pulse refers to the unceasing pathway of Ying Qi circulation. However, without respiration, circulation cannot occur; thus, it is said that it responds to breath.
