*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.
