【白胶】
味道甘甜，药性平和或偏温，无毒。主治内伤劳损、精气枯竭、腰痛、身体消瘦虚弱，能补益中气、增强体力，治疗妇人经血闭阻导致的不孕症，止痛，（此处原文缺字，结合语境及下文“不止”推测可能指崩漏或出血等症，但依规则不增添内容，故直译为）安止不住的症状，四肢酸痛，多汗，淋沥不尽，以及跌打骨折损伤。长期服用可使身体轻盈并延年益寿。又名鹿角胶。产于云中郡，由煮鹿角制成。
遇火加热效果良好，畏惧大黄。现在很少有人再煮制使用，只有制作角弓时还在用，这也说明这种胶的用途所在。在方药中使用也很少，但道家炼丹时常需用到它。制作白胶的方法，先用米汁浸泡七天使其变软，然后进行煮煎，就像制作阿胶的方法一样。另一种方法是将角细切，与一片干牛皮一起煮，角就会消烂；如果不这样做，两者相互排斥，煮一百年也不会熟透。
【谨案】麋鹿角胶，只需煮取浓汁再次煎炼，就成了胶，何必非要煮到烂呢？想要煮烂也不难，这大概是没见到煮胶的过程，错误地说了这番话。
【阿胶】
味道甘甜，药性平和或微温，无毒。主治心腹内部出血，极度劳累时像疟疾一样发冷发热，腰腹痛，四肢酸痛，女子下血，（此处原文缺字，同上文），身体消瘦虚弱，阴气不足，脚酸不能久站，滋养肝气。长期服用可使身体轻盈、增强气力。又名傅致胶。产于东平郡，由煮牛皮制成。产自东阿县。
畏惧大黄，遇火加热效果良好。产自东阿，所以叫阿胶。现在京城也能制作，使用的牛皮有老有少，制成的胶也有清浊之分。凡有三种：清薄的，用于书画；浓而清的，名为盆覆胶，用于药用，使用时都要用火烤炙，做丸散需要极干燥，入汤剂则轻微烤炙即可；浑浊黑的，可用于粘合物品，不入药。加入一片鹿角就能成胶，否则就不能成胶。
【醍醐】
味道甘甜，药性平和，无毒。主治风邪痹气，通润骨髓。可用作外敷按摩的药，药性寒冷滑利，功效优于酥油，产生于酥油之中。这是酥油的精华液。好的酥油一石可以提取三到四升醍醐，经过反复捣碎炼制，储存在容器中，待其凝固后，从中间穿到底部便能流出得到它。陶弘景说：做成黄白色的饼，这是没有通达事理的说法。（新附）
[Baijiao (Deer Horn Glue)]
The taste is sweet, the nature is neutral or warm, and it is non-toxic. It primarily treats internal injury from overwork, exhaustion of essence and vitality, lower back pain, emaciation, and tonifies the middle jiao to augment qi. It treats amenorrhea due to blood stasis leading to infertility, alleviates pain, [text missing in original] stops bleeding/flow, soreness and pain in the four limbs, hyperhidrosis, dribbling discharge, and fractures with soft tissue injuries. Long-term consumption lightens the body and prolongs life. It is also known as Lujiaojiao (Deer Antler Glue). It originates from Yunzhong Commandery and is made by boiling deer antlers.
It works well when heated by fire and is incompatible with Dahuang (Rhubarb Root). Nowadays, few people boil it for use; it is mainly used in making horn bows, which indicates its utility. Its use in herbal prescriptions is rare, but Daoist practitioners often require it. The method for making Baijiao: first soak the antlers in rice water for seven days until soft, then boil and decoct them, similar to the method for making Ejiao. Another method involves finely chopping the antlers and boiling them with a piece of dry cowhide; the antlers will dissolve. If not done this way, they repel each other, and even after a hundred years, they will not soften.
[Commentary]: For Ejiao (Elk Antler Glue), one merely needs to boil to obtain a thick liquid and re-decoct it to form glue. Why must it be boiled until rotten? Making it rotten is not difficult. This statement is likely erroneous, stemming from a lack of observation of the actual glue-making process.
[Ejiao (Donkey-Hide Glue)]
The taste is sweet, the nature is neutral or slightly warm, and it is non-toxic. It primarily treats internal uterine bleeding (Neibeng), severe exhaustion manifesting as chills resembling malaria, lower back and abdominal pain, soreness and pain in the four limbs, vaginal bleeding in women, [text missing in original], emaciation, deficiency of yin qi, leg soreness preventing prolonged standing, and nourishes liver qi. Long-term consumption lightens the body and augments qi. It is also known as Fuzhijiao. It originates from Dongping Commandery and is made by boiling cowhide. It comes from Dong'e County.
It is incompatible with Dahuang (Rhubarb Root) and works well when heated by fire. Because it comes from Dong'e, it is named Ejiao. Nowadays, it can also be produced in the capital. The hides used vary in age, resulting in clear or turbid glue. There are three types: thin and clear glue is used for calligraphy and painting; thick and clear glue, named Penfu Jiao, is used medicinally. When used medicinally, it is roasted over fire; for pills and powders, it must be extremely dry; for decoctions, slight roasting suffices. Turbid and black glue is used for adhesives and is not used in medicine. Adding a piece of deer antler helps it set into glue; otherwise, it will not coagulate properly.
[Tihu (Clarified Butter/Ghee)]
The taste is sweet, the nature is neutral, and it is non-toxic. It primarily treats wind-pathogenic bi-syndrome (obstruction) and moistens/nourishes bone marrow. It can be used as a topical massage agent. Its nature is cold and purgative/lubricating, and its efficacy surpasses that of Su (Butter/Milk Fat), as it is derived from Su. This is the essence of Su. From one dan (a unit of volume) of high-quality Su, three to four sheng (a unit of volume) of Tihu can be obtained. It is processed by repeated pounding and refining, stored in vessels, allowed to solidify, and then extracted by piercing through the center to the bottom. Tao Hongjing stated: "Made into yellow-white cakes." This is an ignorant statement. (Newly added)
