今西戎亦有之，其色差淡而明澈。南方者色深而重浊，彼土人多碾为物形。若谓千年
茯苓所化，则其间有沾着蜾蠃蜂蚁，宛然完具者，是极不知也。《地理志》云∶“林邑多琥
珀，实松脂所化耳。”此说为胜，但土地有所宜不宜，故有能化有不能化者。张茂先又为“
烧蜂窠所作”，不知得于何处。以手摩热，可以拾芥。余如经。
一如蒲黄，但其味差淡。治产后壮热、头痛颊赤、口干唇焦、多烦躁渴、昏闷不爽。
松花、川芎、当归、石膏、蒲黄五物等同为末，每服二钱，水二合，红花二捻，同煎七分，
去滓，粥后温温细呷。
松子，多东海来，今关右亦有，但细小味薄，与柏子仁同治虚秘。
取脂以疗马 疥。今未见用松脂者。老人虚秘，柏子仁、大麻子仁、松子仁等分，同研
，溶白蜡，丸桐子大。以少黄丹汤，服二三十丸，食前。尝官陕西，每登高望之，虽千万株
，皆一一西指。盖此木为至坚之木，不畏霜雪，得木之正气，他木不逮也。所以受金之正气
所制，故一一向之。
桂大热。《素问》云∶辛甘，发散为阳。故汉张仲景桂枝汤，治伤寒表虚皆须此药，是
专用辛甘之意也。《本草》第一又云∶“疗寒以热药”。故知三种之桂，不取菌桂、牡桂者
，盖此二种，性止温而已，不可以治风寒之病。独有一字桂，《本经》言甘辛大热，此正合
《素问》辛甘发散为阳之说，尤知菌、牡二桂不及也，然《本经》只言桂，仲景又言桂枝者
，盖亦取其枝上皮。其木身粗浓处，亦不中用。诸家之说，但各执己见，终无证据。今又谓
之官桂，不知缘何而立名。虑后世为别物，故书之。又有桂心，此则诸桂之心，不若一字桂
也。
如今西戎地区也有这种药材，其颜色较淡且清澈透明。南方的琥珀颜色深重且浑浊，当地人多将其碾磨成各种器物形状。如果说它是千年茯苓所化，那么其中夹杂的蜾蠃蜂和蚂蚁都完好无损，这完全是极不知晓的表现。《地理志》记载：“林邑多产琥珀，实际上是松脂所化。”这种说法更为合理，只是土地有适宜与不适宜的区别，所以有的能转化，有的不能转化。张茂先又说是“燃烧蜂巢所作”，不知依据是什么。用手摩擦发热后，可以吸附芥子。其余内容如经典记载。
（琥珀）功效如同蒲黄，但其味道稍淡。用于治疗产后壮热、头痛面颊发红、口干唇焦、烦躁口渴、神志昏闷不适。将松花、川芎、当归、石膏、蒲黄五味药一同研为细末，每次服用二钱，加水二合，红花两捻，共同煎煮至七分，滤去药渣，饭后温热细细饮用。
松子，大多来自东海，如今关右地区也有，但颗粒细小、味道淡薄，可与柏子仁同治虚性便秘。
取松脂来治疗马疥疮。如今未见使用松脂的情况。老人虚性便秘，用柏子仁、大麻子仁、松子仁等分，一同研磨，加入溶化的白蜡，制成梧桐子大小的丸剂。用少量黄丹汤送服，每次二三十丸，饭前服用。曾经任职陕西时，每登高远望，即使千万株松树，也都一一向西指。大概因为这种树木是极其坚硬的木材，不畏霜雪，得木之正气，其他树木比不上它。所以受金之正气的制约，因此一一向西指。
桂性大热。《素问》说：辛甘味发散属阳。所以汉代张仲景的桂枝汤，治疗伤寒表虚证都必须用此药，这是专门运用辛甘发散之意。《本草》第一卷又说：“治疗寒病用热药。”由此可知三种桂中，不选用菌桂、牡桂的原因，是因为这两种药性仅止于温，不可以治疗风寒疾病。唯独有一种字桂，《本经》言其味甘辛、性大热，这正符合《素问》辛甘发散为阳的说法，更知道菌桂、牡桂不如它。然而《本经》只说“桂”，张仲景又说“桂枝”，大概是取其枝条上的皮。树干粗壮浓密处，也不中用。各家说法，只是各执己见，最终没有证据。现在又称之为官桂，不知因何而立名。担心后世混淆其他物品，故记录于此。又有桂心，这是各种桂的中心部分，不如字桂好。
Now in the Western Regions, this substance also exists; its color is lighter and clearer. In the South, the color is deeper and turbid, and local people often grind it into various shapes. If one claims it is transformed from thousand-year-old Poria Cocos (Fu Ling), then the fact that wasps and ants are found within it perfectly intact shows extreme ignorance. The *Geographical Records* state: "Linyi produces much Amber, which is actually transformed from pine resin." This explanation is superior, but due to differences in land suitability, some can transform while others cannot. Zhang Maoxian further claimed it was made from "burned beehives," but the source of this claim is unknown. When rubbed by hand until warm, it can attract mustard seeds. Other details remain as recorded in the classics.
Its efficacy is similar to that of Sparganii Pollen (Pu Huang), but its taste is slightly milder. It treats postpartum high fever, headache with red cheeks, dry mouth and scorched lips, excessive irritability and thirst, and mental confusion or discomfort. Grind Pine Flower (Song Hua), Ligusticum Chuanxiong Rhizome (Chuanxiong), Angelica Sinensis Radix (Danggui), Gypsum Fibrosum (Shigao), and Sparganii Pollen (Pu Huang) into a fine powder. Take two qian per dose, add two he of water and two pinches of Carthamus Tinctorius Flower (Honghua), decoct together until reduced to seven parts, filter out the dregs, and drink slowly while warm after meals.
Pine Seeds (Songzi) mostly come from the East Sea region; now they are also available in the Guanxi area, but they are smaller and have a thinner flavor. They can be used with Biota Seed (Baizi Ren) to treat deficiency-type constipation.
Pine Resin (Songzhi) is taken to treat equine scabies. Currently, the use of Pine Resin is rarely seen. For elderly patients with deficiency-type constipation, use equal parts of Biota Seed (Baizi Ren), Cannabis Sativa Seed (Dazhuren), and Pine Seed (Songziren). Grind them together, melt White Beeswax (Baila), and form pills the size of paulownia seeds. Administer twenty to thirty pills with a small amount of Yellow Lead Oxide (Huandan) decoction before meals. While serving as an official in Shaanxi, whenever I climbed high to look around, even thousands of pine trees all pointed westward. This is likely because this tree is extremely hardy, unafraid of frost and snow, possessing the upright qi of wood, which other trees lack. Therefore, it is constrained by the upright qi of metal, causing it to point westward.
Cinnamon Twig (Guizhi) is very hot. The *Suwen* states: "Acrid and sweet flavors disperse and belong to Yang." Thus, in the Han Dynasty, Zhang Zhongjing's Guizhi Tang (Cinnamon Twig Decoction) requires this herb for treating exterior deficiency patterns of Cold Damage, specifically utilizing the principle of acrid-sweet dispersion. The first volume of the *Bencao* also states: "Treat cold diseases with hot herbs." From this, we know that among the three types of cinnamon, Jun Gui (Jun Gui) and Mu Gui (Mu Gui) are not selected because their properties are merely warm, insufficient for treating wind-cold diseases. Only the so-called "Yi Zi Gui" (Single-Character Cinnamon) is described in the *Ben Jing* as having a sweet and acrid flavor and being very hot, which aligns perfectly with the *Suwen*'s statement that acrid-sweet disperses and belongs to Yang. This confirms that Jun Gui and Mu Gui are inferior. However, the *Ben Jing* only mentions "Gui," while Zhang Zhongjing mentions "Guizhi"; this is likely because he utilized the bark from the branches. The thick trunk part is not useful. Various schools of thought hold their own views without evidence. Now it is also called Official Cinnamon (Guan Gui); the origin of this name is unknown. To prevent future confusion with other substances, I record this here. There is also Guixin (Cinnamon Heart), which refers to the center of various cinnamons, but it is not as effective as Yi Zi Gui.
