【蚺蛇】
又名南蛇。又被称为埋头蛇。体型大的直径有二到三围。在地面上爬行时不抬起头的是真品。抬起头来的就不是真品。（出自《真白》）
真正的胆狭长且通体黑色，皮膜极薄。用舌头舔尝味道甜中带苦。（出自《又》）挑取像粟米大小的一块，放入清水中。它会浮游在水面上，回旋行走。（不要放太多，放多了也会沉下去散开。）那些用猪胆、虎胆伪造的，放入水中虽然也能游走，但动作迟缓罢了。
【胆】
味苦，带有甘味，气寒，有小毒。气味轻薄而滋味浓厚，属阴，主降。归入手少阴心经、足厥阴肝经、足太阴脾经、足阳明胃经。能明目，去除翳膜，治疗眼睛肿痛，凉血，止血痢和虫蛊引起的下血，杀虫。主治心腹疼痛，下部疮疡，消除疳积，治疗五疳。
【肉】

【鲤鱼】
这种鱼胁部的鳞片只有一道，从头到尾不分大小，数量都是三十六片，所以被视为至阴之物。阴极则阳复生。
气味甘平。煮食可治疗水肿、脚部胀满，下行水气，利尿。
【附方】治疗水肿胀满：取赤尾鲤鱼一斤，剖开，注意不要让水和盐接触鱼肉。将生矾五钱研成粉末，填入鱼腹内，用火纸包裹……（原文此处似有缺漏，通常为煨熟或煮熟后服用以验疗效）。

[Pythonia (Reticulated Python)]
Also known as Nan She (Southern Snake). Also called Mai Tou She (Head-Burying Snake). Large specimens have a girth of two to three *wei* (a traditional unit of measurement). Those that crawl on the ground without raising their heads are genuine. Those that raise their heads are not genuine. (From *Zhen Bai*)
The genuine gallbladder is narrow and long, entirely black, with extremely thin membranes. It tastes sweet yet bitter when licked. (From *You*) Take a piece the size of a millet grain and place it in clear water. It floats on the surface and moves in circles. (Do not use too much; if used excessively, it will sink and disperse.) Counterfeits made from pig or tiger gallbladders may also move in water but do so slowly.
[Gallbladder]
Taste: Bitter with a hint of sweetness. Nature: Cold. Toxicity: Slightly toxic. Properties: Light in qi, heavy in taste, Yin in nature, descending. Meridian Tropism: Hand Shaoyin Heart Channel, Foot Jueyin Liver Channel, Foot Taiyin Spleen Channel, Foot Yangming Stomach Channel. Actions: Brightens the eyes and removes nebulae, treats eye swelling and pain, cools blood, stops bloody dysentery and bleeding caused by parasites, kills parasites. Indications: Epigastric and abdominal pain, ulcers in the lower body, eliminates malnutrition syndromes (*Gan*), treats the five types of *Gan*.
[Meat]
Taste: Sweet. Nature: Warm. Toxicity: Slightly toxic. Actions: Expels miasma, relieves wind-pain in hands and feet, kills three types of parasites, removes dead flesh, treats skin wind-toxicity, leprosy, scabies, and other severe sores, treats pediatric *Gan* sores. When traveling to Lingnan, consuming python meat prevents invasion by miasmic toxins. (From *Quan*)
[Case Record] Lu Yuanqin suffered from leprosy, with only his nose remaining intact. On the fifth day of the fifth lunar month, he collected python for tribute. Someone suggested that snake meat could treat wind diseases, so he consumed it. After three to five days... [Text fragmentary].
[Usage] Python wine treats carbuncles, tendon spasms, bone pain, bi-syndrome numbness and itching, kills parasites, expels miasma, and treats leprosy, scabies, tinea, and severe sores. Take one jin (approx. 500g) of python meat, Qiang Huo (Notopterygium Rhizome)... [Text fragmentary].
[Carp]
This fish has a single row of scales along its flanks, numbering exactly thirty-six from head to tail regardless of size. Therefore, it is considered a substance of extreme Yin. When Yin reaches its extremity, Yang regenerates.
Taste: Sweet. Nature: Neutral. Actions: Boiled and eaten, it treats edema and leg fullness, directs water downward, and promotes urination.
[Prescription] For treating edema and distension: Take one jin of red-tailed carp, split open. Ensure no water or salt touches the flesh. Grind five qian (approx. 18.75g) of raw alum into powder, insert it into the abdominal cavity, wrap in fire paper... [Text fragmentary] to verify efficacy.
[Gallbladder]
Taste: Bitter. Nature: Cold. Minister Herb: Shu Qi (Sophiae Herba). Actions: Treats heat-induced redness and pain in the eyes, chaotic red vessels, external cataracts, blurred vision, night blindness, and dry painful eyes. Combined with grass carp gallbladder, it treats internal cataracts.
[Brain]
Treats deafness.
[Usage]
Taste: Salty. Nature: Neutral. For ear worms with continuous pus and blood discharge: Use three jin of carp brain, one brain specimen, and one set of intestines. Wash and chop finely. Add one portion of wu ma zi (Sesamum indicum seeds), stir-fried... [Text fragmentary], pound together into a paste, warm slightly over low fire, wrap in cloth, and apply to the ear. After about the time it takes to eat a meal, white worms will emerge. Once expelled, the condition heals. Avoid wind and cold.
[Discussion] Danxi stated that all fish in water never rest for an instant, thus they can stir up wind, because they belong to "Yin within Yang." Therefore, the *Su Wen* states that fish cause heat in the middle jiao.
