今茶也。其文有陆羽《茶经》、丁谓《北苑茶录》、毛文锡《茶谱》、蔡宗颜《茶
山节对》。其说甚详。然古人谓其芽为雀舌、麦颗，言其至嫩也。又有新芽一发便长寸余，
微粗如针。惟芽长为上品，其根干、水土力，皆有余故也。如雀舌、麦颗，又下品。前人未
尽识，误为品题。唐人有言曰∶“释滞消壅，
一日之利暂佳。”斯言甚当，饮茶者宜原其始终。又，晋温峤上表“贡茶千斤，茗三百斤。
”郭璞曰∶“早采为茶，晚采为茗。”茗，或曰 （尺兖切），叶老者也。
桑根白皮条中，桑之用稍多，然独遗乌椹，桑之精英尽在于此。采摘，微研，以
布滤去滓，石器中熬成稀膏，量多少入蜜，再熬成稠膏，贮瓷器中。每抄一二钱，食后、夜
卧，以沸汤点服。治服金石发热渴，生精神，及小肠热，性微凉。
一名棘针，一名棘刺。按经如此甚明，诸家之意强生疑惑，今掠不取，求其经而可矣
。其白棘，乃是取其肥盛紫色，枝上有皱薄白膜先剥起者，故曰白棘。取白之意，不过如此
。其棘刺花，乃是棘上所开花也，余无他义。今人烧枝取油，涂垢发，使垢解。
条中与《图经》所说各未尽。此物大通利关膈热塞，其清香为百药之先。大人、小儿
风涎闭壅及暴得惊热，甚济用。然非常服之药，独行则势弱，佐使则有功。于茶亦相宜，多
则掩茶气味，万物中香无出其右者。西方抹罗矩吒国，在南印度境，有羯布罗香。干如松株
，叶异，湿时无香。采，干之后折之，中有香，状类云母，色如冰雪，此龙脑香也。盖西方
亦有。
[Wuyi]
It is warm in nature and indispensable for treating cold-slippery syndrome of the Large Intestine (Da Chang Han Hua). It must be administered as pills combined with other herbs. Its warmth disperses and drives away cold pathogenic factors.
[Tea]
This refers to tea today. Relevant texts include Lu Yu's *Cha Jing* (Classic of Tea), Ding Wei's *Bei Yuan Cha Lu* (Record of Bei Yuan Tea), Mao Wenxi's *Cha Pu* (Tea Manual), and Cai Zongyan's *Cha Shan Jie Dui*. The explanations are very detailed. However, ancients referred to its tender buds as "Sparrow Tongue" (Que She) and "Wheat Kernel" (Mai Ke), indicating extreme tenderness. There are also new buds that grow over an inch long upon emergence, slightly coarse like needles. Only those with longer buds are considered first-rate grade, because their roots and stems possess abundant Qi and strength from soil and water. Those resembling sparrow tongues or wheat kernels are considered inferior grade. Predecessors failed to fully recognize this and made erroneous evaluations. A Tang dynasty saying goes: "Relieving stagnation and eliminating obstruction offers only temporary benefit for a day." This statement is quite apt; those who drink tea should understand its principles thoroughly. Furthermore, Jin dynasty official Wen Qiao submitted a memorial stating: "Tribute of one thousand jin of tea, three hundred jin of ming." Guo Pu said: "Harvested early is called cha (tea), harvested late is called ming (strong tea)." Ming, pronounced "chi yan qie," refers to older leaves.
[Sangbaipi / Wushen]
Among the parts of the mulberry tree, Sangbaipi (Cortex Mori) is used somewhat more frequently, yet Wu Shen (Morus Fruit) was uniquely omitted. The essence of the mulberry resides entirely here. After harvesting, lightly grind it, filter out the dregs using cloth, and boil into a thin paste in stone vessels. Add honey according to quantity, then boil again into a thick paste, storing it in porcelain containers. Take one or two qian after meals and before sleep, mixed with boiling water. It treats fever and thirst caused by taking mineral drugs (Jin Shi), generates spirit/vitality, and clears heat in the Small Intestine. Its nature is slightly cool.
[Baiji]
Also known as Ji Zhen (Spine Needle) and Ji Ci (Spine Thorn). The classics state this clearly; various schools create unnecessary confusion. We omit these here and seek only what aligns with the classics. The so-called Baiji (White Spine) refers to branches that are plump, lush, purple in color, with wrinkled thin white membranes peeling off first on the branches, hence named "White Spine." The meaning of "white" is merely this. Ji Ci Hua (Spine Thorn Flower) simply means the flowers blooming on the spine tree, with no other hidden meanings. Nowadays, people burn branches to extract oil, applying it to dirty hair to dissolve grime.
[Longnao]
The descriptions in the main text and *Tu Jing* (Illustrated Classic) are not exhaustive. This substance greatly promotes the unblocking of heat obstruction in the diaphragm and chest. Its clear fragrance is the foremost among all medicinal herbs. It is highly effective for wind-phlegm obstruction and sudden onset of fright-heat in adults and children. However, it is not a drug for daily consumption. Used alone, its power is weak; accompanied by guiding herbs, it achieves merit. It pairs well with tea, though excessive use masks the aroma of tea. Among all things, no fragrance surpasses it. In the country of Moluo Juzha in the West, located within the borders of Southern India, there is Ji Buluo Xiang (Agarwood/Aloeswood). When dry, it resembles pine trunks; the leaves differ, and it has no fragrance when wet. After harvesting and drying, breaking it reveals fragrant resin inside, resembling mica in shape and ice/snow in color. This is Longnao Xiang (Borneol Camphor). It seems this exists in the West as well.
