[Meat]
[Flavor and Nature] Sweet, Cold, Slightly toxic.
Tao Hongjing said: Yellow female duck has the best tonifying effect.
Meng Shen said: White duck meat is the best. Black duck meat is toxic, causes slippery intestines, and can trigger cold diarrhea and gout; it should not be eaten. Ducks with white eyes are poisonous and can cause death if consumed.
Li Rui said: People suffering from intestinal wind with bloody stool should not eat it.
Li Shizhen said: Young ducks are toxic, while old ducks are beneficial. The duck tail should not be eaten, as recorded in *Li Ji*. In the past, someone developed a mass after eating duck meat and was cured using Sorghum (*Shumi*); see the entry for Sorghum.
[Indications] Tonify deficiency and eliminate pathogenic factors (from *Ben Cao Shi Yi*). Sores and swelling on the head: Boil with green onion and fermented soybean (*Chi*), drink the juice to relieve sudden irritability and heat (Meng Shen. Use white duck).
[Elucidation] Liu Wansu said: The diuretic effect of duck meat arises from the mutual influence of their qi.
Li Shizhen said: Ducks are waterfowl. To treat water retention and promote urination, use male ducks with green heads, symbolizing water generating wood and the generative nature of wood. To treat consumptive fever and toxicity, use white ducks with black bones, symbolizing metal generating water and the cold,肃 (solemn/clearing) nature of water.
[Additional Prescriptions] Three old prescriptions, one new prescription.
White Phoenix Paste: Ge Kejiu said: Treats chronic deficiency with fever, cough with phlegm, hemoptysis, and hematemesis. Take one sheng of Ginseng, Poria, and Pingwei San powder, bind tightly. Place one clay pot, put the duck inside, and slow-roast over charcoal fire. Add one bottle of aged wine in three portions. Continue until the wine is dry. Remove, and eat the duck meat and dates. Prepare frequently until cured. (From *Shi Yao Shen Shu*) Abdominal distension due to water accumulation, scanty urine: *Bai Yi Fang*: Boil a male duck with green head, drink the juice, cover tightly to induce sweating. *Xin Jing*: Treats ten types of severe water diseases nearing death. Use one male duck with green head, prepare and chop as usual, cook with rice and five flavors into porridge. Another method: Clean one white duck, place half a sheng of glutinous rice, along with ginger and pepper, inside the duck belly, sew it up, steam, and eat.

[Indications] Decoct and take to treat edema and promote urination (Gong said: Ancient formulas include Duck Head Pill).
[Additional Prescriptions] One new prescription.
Duck Head Pill: Treats acute Yang-water edema, red face, irritability, panting, and difficult urination. Its efficacy is miraculous; this is a formula passed down by Peihe Dongfang. Use two liang of sweet Descurainia seed (stir-fried) boiled into paste, two liang of Stephania root powder. Mix with blood from a green-headed duck and the duck head, pound for three thousand strikes, form pills the size of梧子 (wuze). Take seventy pills per dose with Wood Tong decoction, three times daily. Add one liang of Polyporus. (From *Waitai Mi Yao*)
[Brain]
[Indications] Frostbite; applying duck brain is effective (Li Shizhen).
[Blood] (White duck blood is preferred)
[Flavor and Nature] Salty, Cold, Non-toxic.
[Indications] Resolves various toxins (*Bie Lu*). Drink hot to resolve wild gecko (*Yege*) toxicity. If the person is already dead, pouring it into the throat revives them (Meng Shen). Hot blood resolves poisoning from gold, silver, cinnabar/mineral stones, and arsenic, leading to immediate recovery (Li Shizhen).
[Additional Prescriptions] Three new prescriptions.
Sudden collapse or death from evil qi, or sudden cessation of breath while lying down: Take a male duck, cut off its head near the deceased's mouth, drip blood into the mouth. Externally, blow air into the lower body using a bamboo tube; change people if necessary until qi flows and life returns. (From *Zhou Hou Bei Ji Fang*)
Resolve hundred gu poisons: Drink hot white duck blood. (From *Guang Ji*)
Infant white dysentery resembling fish jelly: Kill a white duck, collect blood, soak in boiling wine, and administer to stop symptoms. (From *Zhai Xuan Fang*)

[Indications] For bone splinters stuck in throat: Roast, grind, take one qian with water for immediate relief, utilizing its resolving and guiding properties (Li Shizhen).
[Egg]
[Flavor and Nature] Sweet, Salty, Slightly Cold, Non-toxic.
Shen said: Excessive consumption generates cold qi, causing shortness of breath and chest/back oppression. In children, excessive consumption leads to weak legs. Salted and stored eggs are suitable for consumption.
Shiliang said: Consuming it when suffering from sores/toxins causes malignant flesh to protrude.
Hongjing said: Do not consume with turtle meat or plums, as it harms people. Consuming with mulberry fruit causes difficulties in childbirth.
[Indications] Heat in the heart, abdomen, chest, and diaphragm (*Ri Hua*).
[Elucidation]
Li Shizhen said: Nowadays, people salt-cure ducks using various methods. Folklore suggests roasting salty eggs for infants with diarrhea/dysentery, which occasionally works. This is because duck meat treats dysentery, and fried salt also treats bloody dysentery.
[Duck Droppings (Synonymous with Horse Dung)]
[Flavor and Nature] Cold, [No specific flavor mentioned]
[Indications] Kills mineral drug toxicity, resolves binding/stagnation, disperses accumulated heat (*Bie Lu*). Mainly treats heat toxicity and toxic dysentery. Also [reduces swelling/toxins], immediately dissipates. Effective for earthworm bites (Meng Shen). Juice extracted and taken orally resolves [toxicity].
