[Musk]
Tasting bitter and pungent, with a fragrant and intense aroma, it is a superior medicine for unblocking orifices and benefiting apertures. The musk deer, a mountain animal, feeds on aromatic trees and herbs such as cypress leaves; thus, the qi gathers in its navel, condensing into this fragrance. When full, the interior of the navel becomes painfully urgent, and the deer scratches it out itself. Some claim it forms from consuming many snakes, which is incorrect. Musk's pungent and aromatic nature moves and penetrates, reaching from the interior to the exterior, causing hair follicles and bone joints to open, allowing evil pathogens to exit. Therefore, it treats lateral malignant qi, spirit/gu poison, warm malaria, zhong-e (sudden illness due to turbid epidemic qi), sudden severe pain in the heart and abdomen, convulsions and epilepsy, and abortion. All ointments and powders for carbuncles and sores utilize its ability to open orifices, unblock meridians, and penetrate muscle and bone. Additionally, its bitterness can kill parasites, and its pungency can dissipate corneal opacities.

Musk dispels malignant qi, kills spirits, warm malaria, and gu poison, resolves convulsions and epilepsy, unblocks orifices, calms the heart and spirit, expels wind-phlegm, eliminates distension, induces abortion, removes three parasites (intestinal worms), treats zhong-e, sudden severe abdominal pain, and cloudy corneal opacities. However, its efficacy lies in its moving and penetrating nature, which consumes yin and depletes yang. Wherever musk falls, grass withers and turns yellow; if musk contacts wine, the wine spoils. This is because its moving nature steals and leaks true qi. Thus, Zhu Danxi stated: For wind affecting the five zang organs, musk is contraindicated as it drains defensive qi; therefore, those with deficiency patterns should not use it lightly. Patients with consumption and weakness, and pregnant women, must strictly avoid wearing it.

Main Indications (Integration of Smallpox and Rashes): Inhaling its scent causes smallpox pustules to crust over; ingesting it promotes eruption. For cases where smallpox covers the body but fails to erupt, remains latent and itchy, or presents as black depression, a small amount may be used to penetrate the heart orifice, facilitating the expulsion of toxins. Do not use excessively, lest it hasten blistering leading to collapse and death. It is contraindicated unless there is depression or blackening.

[Dog Penis]
Also known as dog essence, its flavor and odor are similar to that of the horse penis, and its functions are comparable. Its nature specifically tonifies the true fire of the right kidney and Mingmen (Gate of Vitality). Thus, it enhances male potency, warms and fills the semen, enabling procreation. Women's twelve types of leukorrhea are caused by deficiency-cold of the Chong and Ren vessels. Being salty and warm, it enters the lower jiao and tonifies and warms these two vessels, thus treating them. It should be harvested during the upper fu days of the sixth lunar month and air-dried in the shade for one hundred days.

[Dog Skull Bone]
The skull bone of a yellow dog is best. Calcined to ash, it treats traumatic injuries (golden wounds) to stop bleeding, chronic deficiency-related foul ulcers, red and white leukorrhea in women, trauma-induced yang damage, whip marks, and foul ulcers. It is also used for mastitis and breast abscesses. These applications rely on its salty nature entering the blood, sweet nature tonifying blood, and warm nature harmonizing blood, yielding significant effects.

[White Dog Blood]
Enters the Heart meridian to tonify blood, treating epilepsy caused by blood deficiency.

[Dog Meat]
Tasting salty and sour, with a warm temperature, belonging to Earth, non-toxic. It is meat of the Spleen and Stomach. The five zang organs rely on the Spleen and Stomach for nourishment; when the Spleen and Stomach are tonified, the five zang organs are stabilized. Thus, it tonifies severe injuries, strengthens male potency, warms the waist and knees, boosts qi and strength, tonifies blood vessels, thickens the stomach and intestines, fills the lower jiao, and marrow. Yellow dog meat benefits the Spleen; black dog meat tonifies the Kidney; meat of other colors is unsuitable. Both internal and external kidneys assist sexual function, but meat should not be consumed in excess as it causes xiao-ke (wasting-thirst). Individuals with robust qi and excessive heat/fire should avoid it. Pregnant women eating it may give birth to mute children; consuming it after febrile diseases can be fatal.

[Dog Gallstone/Gem]
Similar to how cattle have gallstones. Since dogs have hot nature, their gem is likely bitter and warm. People use it to treat dysphagia (ye syndrome) because bitterness directs downward and warmth promotes circulation. It also treats carbuncles, sores, and boils, often combined with toad venom, brain/musk, realgar, frankincense, and myrrh. However, since its nature is hot and good at resolving dysphagia caused by phlegm and deficiency-cold, it may be used temporarily. If dysphagia is caused by blood depletion and Spleen/Stomach weakness, it is contraindicated.

[Dog Genitalia]
Erects the male penis and treats female deficiency-cold leukorrhea and leakage. The meat is warm and hot, stabilizes the five zang organs, boosts qi and strength, strengthens male potency, repairs injuries, and warms the waist and knees. It should not be roasted or eaten with garlic. Pregnant women should avoid it.

Main Indications (Integration of Smallpox and Rashes): Dog flies (likely referring to a specific preparation or insect related to dog flies) treat inverted smallpox with black facial complexion. Use seven pieces, grind finely, mix with a little wine, and take orally. They are abundant and easy to obtain in summer; in winter, they hide in the ears.
