In the "Collected Explanations" note for Tofu in Li Shizhen's *Bencao Gangmu* (*Compendium of Materia Medica*), it is stated: The tofu skin (Fu Pi) can be used in cuisine, but the soy milk (Jiang) and fermented tofu (Ru) are omitted. Furthermore, Sesame (Huma) can also be made into tofu, yet this is also omitted in the *Bencao Gangmu* under the Sesame entry. I now supplement all these, collectively naming them "Fu".

Soy Milk (Fu Jiang)
Taste: Sweet with a slight salty flavor; Nature: Neutral. Functions: Clears the throat, removes greasiness, and resolves toxicity from brine coagulants (such as magnesium chloride). According to *Yao Xing Kao* (*Record of Drug Properties*): Taste is sweet with a slight bitter note; Nature is cool. Functions: Clears heat, directs qi downward, and promotes urination.

**Prescription for Taiyang Disease (Cold Damage) with no sweating for ten days**: Zhang Qingzi's Excellent Prescription: Use one large bowl of uncoagulated soy milk, mix in high-quality white honey, heat, and drink. Sweating will ensue, leading to recovery. This is remarkably effective.

**For Hong Kong Foot (Podagra/Gouty arthritis presenting as swelling and pain making walking difficult)**: Apply hot soy milk mixed with powdered Pine Rosin (Song Xiang) evenly to the affected area. After overnight application, walking ability returns, preventing future recurrence.

**Blood in Stool**: *Gu Jin Liang Fang* (*Excellent Formulas Ancient and Modern*): Take one or half a jin (approx. 500g) of Water Chestnut (Biqi). Mix with one large bowl of undiluted soy milk. Heat the soy milk to boiling. Crush the water chestnuts to extract juice, and pour this juice into the hot soy milk while still warm. Drink immediately.

**Salt-induced Asthma (Yan Xiao)**: *Jiu Sheng Ku Hai* (*Sea of Bitterness for Saving Lives*): Add a small amount of sugar to soy milk. Take one bowl every morning on an empty stomach without interruption. Recovery occurs after over one hundred days.

**Treatment for Jaundice**: Liu Yuyi's Verified Formula: Consume one bowl of raw, cold soy milk every morning on an empty stomach. Repeat four to five times for self-healing. Avoid eating raw radishes.

**Phlegm-Fire Roaring Asthma**: *Jing Yan Guang Ji* (*Extensive Collection of Experienced Prescriptions*): Take two liang (approx. 62.5g) of Malt Sugar (YiTang) and one bowl of soy milk. Boil until dissolved and consume in one dose for recovery.

**Treatment for Consumption (Lao Bing) and Spontaneous Sweating**: *Hui Sheng Ji Fang* (*Formulas for Reviving Life*): Clean black beans thoroughly, grind them into soy milk, and boil in a pot until cooked. A skin will form on top. Consume one sheet of this skin, washed down with hot black bean soy milk, for immediate effect. Drinking black soy milk every morning greatly benefits the body and prevents consumption diseases.

**Lung Abscess (Fei Yong) and Lung Flaccidity (Fei Wei)**: Use aged Mustard Green Brine (Jie Cai Lu). Mix half a wine glass of this brine with soy milk daily. After ingestion, a sensation of blockage will move up and down in the chest. After several such episodes, foul pus will be expectorated. Continue daily administration until cured.

**Metrorrhagia (Xue Beng - Profuse Uterine Bleeding)**: *Bu Yao Liang Fang* (*Excellent Prescription Without Medicine*): Mix one bowl of raw soy milk with half a bowl of raw Chinese Chive Juice. Consume once or twice on an empty stomach.

**Wu Miao Tang (Five Wonders Decoction) for Postpartum Conditions and Weakness**: Transmitted by Yu Wenhu: Take one bowl of first-batch soy milk, one sheet of tofu skin, and one raw egg beaten up. Pour into the soy milk. Add fourteen Longan Arils (Gui Yuan Rou) and one liang (approx. 31.25g) of white sugar. Boil together and consume. Eat at dawn on an empty stomach.

Chen Tingqing stated: Soy milk enters the Yin aspect, clearing fire and promoting urination to resolve turbidity. For strangury (Lin Zheng), mixing Liu Yi San (Six-One Powder) with soy milk is excellent. Mixing with egg and white sugar at dawn calms coughs and nourishes blood. Cantonese people cook soy milk into porridge, called Sweet Porridge (Tian Jiang Zhou), which greatly tonifies deficiency and emaciation.

**Tofu Foam (Fu Mo)**
This is the foam that forms on the surface of the water remaining from tofu production. It treats Tinea Manuum/Pedis (Goose Palm Tinea), characterized by peeling skin on palms and soles exposing flesh and blood. Washing with hot foam cures it.

**Tofu Dregs (Fu Zha)**
These are the residues left after making tofu, usually fed to pigs. For medicinal use, raw dregs must be employed.

**Treatment for All Malignant Sores and Unnamed Swellings/Venom**: Highly effective. *Bu Yao Liang Fang*: Bake tofu dregs in a clay pot until hot. Shape into cakes according to the size of the red/swollen area and apply as a plaster. Replace when cool. Continue until healed.

**Blood in Stool**: *Gu Jin Liang Fang*: Stir-fry tofu dregs that have not been washed in water until yellow. Mix with clear tea powder and take orally for cure.

**Treatment for Gan Sore (Childhood Malnutrition Ulcer) and Skirt-Edge Sore**, which are rotten, smelly, and raised at the edges; *Yang Su Yuan Fang*: Mold raw tofu dregs into a cake matching the sore's size. Cleanse with clear tea, dry with silk cloth, then apply the dreg cake and bind with cloth. Change once daily. The sore gradually shrinks, and tissue flattens. This formula was personally tested and proven effective by Fei Qizhang. It can also be applied to foot ulcers caused by insects/maggots.

**Foot Ulcers with Water Pores and Wet/Rotten Skin**: *Bu Yao Liang Fang*: Apply tofu dregs for three days for cure. Keep away from raw water.

**Intestinal Wind Bleeding (Chang Feng Xia Xue - Hematochezia before defecation)**: *Ci Hang Huo Ren Shu* (*Book of Compassion for Saving Lives*): Snow Flower Vegetable refers to tofu dregs. Use dregs containing unfiltered liquid. Stir-fry in a pot with water until dry, then grind to powder. Take three qian (approx. 9g) per dose. If bloody clots are present, take with brown sugar water. Three times daily. Even in chronic, critical cases, this is miraculously effective.

**Tofu Skin (Fu Pi)**
Taste: Sweet; Nature: Neutral. Functions: Nourishes the stomach, facilitates childbirth (slippery fetus), and detoxifies.

**Infants with Net-like Spider Sores All Over the Body, Intense Itching**: *Ren Hui Bian*: Burn tofu skin until carbonized but retaining properties (Cun Xing). Mix with sesame oil and apply externally for self-healing.

**Lu Tou Ju (Head Carbuncle/Abscess)**: *Ci Hui Xiao Bian*: Catch five to six geckos (Bi Zi). Wrap in tofu skin and consume. Cured upon completion.

**Cold Cough**: Liu Yuyi's Verified Formula: Burn dried tofu skin until carbonized, grind to powder. Take with hot aged rice wine. Consume forty to fifty sheets for cure.

**Hydrops Abdominis (Shui Gu Zhang - Ascites)**: *Zhong Fu Tang Fang*: Remove veins from old Banana Leaf Fan, burn to ash (5 fen / approx. 1.5g). Process Croton Seed (Qian Jin Zi) to remove oil shell (2.5 qian / approx. 7.8g). Use Talcum Powder (Hua Shi, 2 fen / approx. 0.6g). Grind all to fine powder. Wrap in tofu skin wrapper. Take with boiling water. Ten doses yield cure.

**Fermented Bean Curd (Fu Ru)**
Also known as Shu Ru. Made by pickling tofu, then adding wine lees or sauce. Taste: Salty and sweet; Nature: Neutral. Functions: Nourishes the stomach and harmonizes the middle jiao.

**Pot Crust (Fu Ba)**
This is the scorched crust formed at the bottom of the soy milk cooking pot. For medicine, sun-dry, roast, and grind to powder, or crush raw to make pills. Both are usable. *Yao Xing Kao* calls it "Guo Zhi". Functions: Opens the appetite, eliminates stagnation, and drives out accumulation.

**Treatment for Strangury/Turbid Urine and Blood Tonification**: *Ci Hang Huo Ren Shu* contains Wu Xiao Wan (Five Efficacy Pills): Take one liang (approx. 31.25g) of tofu pot crust and one qian (approx. 3.1g) of Coptis Rhizome (Chuan Lian). Pound together and roll into pills the size of paulownia seeds. Take five qian (approx. 15g) per dose. For red leukorrhea, swallow with honey-boiled water. For white leukorrhea, take with brown sugar water. For heat-strangury with hematuria, take with plain water. For intestinal wind bleeding, take with aged wine.

**Blood-Wind Sore**: First, soak and wash the sore with tofu washing water to remove scabs. Dry with cloth. Apply the aforementioned powder (half of the Coptis and Pot Crust mixture reserved during pill-making) mixed with pure sesame oil. Reapply when dry. Self-heals in three to four applications.

**Tofu Washing Water (Fu Gan)**
This is the water drained from tofu production. *Yao Xing Kao* states: Whether coagulated with brine or gypsum, tofu possesses heat-clearing properties. The nature is cool/clear. Functions: Promotes bowel movements, descends phlegm, relieves urinary retention (Long Bi), and cleans clothes by removing grease.

**Sesame Paste (Ma Fu)**
Made from sesame flour/powder. Taste: Sweet; Nature: Neutral. Functions: Moistens skin and lubricates the intestines.

**Detoxification**: Jiang Yi's *Yao Jing Zi Sheng Fu* (*Poem of Generating Life in the Mirror of Medicine*) states: Sesame paste and bean flour clear the intestines and stomach.
