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

亦有。
【芜荑】
性温，是治疗大肠寒滑证不可缺少的药物，必须配合其他药物制成丸剂服用。其性温而能散走寒气。
【茶】
这就是现在的茶。关于茶的文献有陆羽的《茶经》、丁谓的《北苑茶录》、毛文锡的《茶谱》、蔡宗颜的《茶山节对》等。其中的解说非常详细。然而古人称其嫩芽为“雀舌”、“麦颗”，是说它极其细嫩。又有新芽刚发出就长一寸多，略微粗硬如针状。只有芽长的是上品，因为它的根干和水土之力都充足有余的缘故。像雀舌、麦颗这样的，又是下品。前人未能完全认识清楚，错误地进行了品评。唐人曾说：“解除郁滞，消除壅塞，一天的利益暂时良好。”这话很恰当，饮茶的人应该探究其始终道理。另外，晋代温峤上表说“进贡茶千斤，茗三百斤”。郭璞说：“早采的叫茶，晚采的叫茗。”茗，有的读音为“尺兖切”，是指叶子老的茶。
【桑白皮/乌椹】
在桑树的各个部位中，桑白皮的使用稍微多一些，但唯独遗漏了乌椹（桑葚），桑树的精华全在于此。采摘后，轻微研磨，用布过滤去渣滓，在石器中熬制成稀膏，根据分量加入蜂蜜，再次熬制成稠膏，储存在瓷器中。每次取一两钱，饭后、睡前，用沸水冲服。用于治疗服用金石类药物引起的发热口渴，生发精神，以及小肠热证，药性微凉。
【白棘】
一名棘针，一名棘刺。按照经典记载如此明确，各家意见强行产生疑惑，现在略去不取，只求符合经典即可。所谓的白棘，是取其肥大茂盛、呈紫色，枝条上有皱缩薄白膜先剥起的那种，所以叫白棘。取“白”的意思，不过如此罢了。棘刺花，就是棘树上开的花，没有其他含义。现在的人烧枝条取油，涂抹在脏头发上，使污垢分解。
【龙脑】
条文与《图经》所说的都未尽善尽美。此物大能通利关膈间的热塞，其清香为百药之先导。对于大人、小儿的风涎闭壅及突然得的惊热，很有疗效。但它不是经常服用的药物，单独使用则效力微弱，配合佐使药则有功效。它与茶也相适宜，用量过多则会掩盖茶的气味，万物中香气没有能超过它的。西方抹罗矩吒国，位于南印度境内，有羯布罗香。干燥时像松树干，叶子不同，湿润时无香味。采摘后，晒干再折断，里面有香脂，形状类似云母，颜色像冰雪，这就是龙脑香。大概西方也有这种香。
[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.
