Abstract: This article presents the complete "Guchi Shenfang" (Teeth-Firming Divine Formula) recorded in the Qing Dynasty text Chen Xiuyuan's Medical Works. It details the nine-ingredient formula, preparation methods, standard brushing protocol, and real-world user feedback for receding gums, loose teeth, and chronic toothache.

Tooth pain isn't a disease — until it strikes, and then it feels like the end of the world.

A few years ago, my dentist looked at my X-ray and said, with all the warmth of a shop manual: "Better to pull it out. Long pain is worse than short pain."

I stared at that wobbly tooth. You only get one set of natural teeth. Once extracted, they're gone forever. I politely declined and made a quiet vow: before surrendering to the drill, I'd scour the classical Chinese medical texts for a gentler way.

That search led me to a treasure — the "Guchi Shenfang" (Teeth-Firming Divine Formula), recorded in the Chen Xiuyuan Medical Works (72 volumes).

I. Historical Origin: A Qing Dynasty Physician's Gift to the People

"Guchi Shenfang" was created by Chen Xiuyuan (c. 1753–1823), a Qing Dynasty scholar-official and renowned physician from Fujian.

Chen was no ordinary doctor. A successful imperial examiner (Juren), he dedicated his spare time to medicine, determined to make the esoteric classics — such as the Shanghan Lun (Treatise on Cold Damage) and Jingui Yaolüe (Essentials from the Golden Cabinet) — accessible to ordinary scholars and practitioners. His annotated editions became standard textbooks for generations. Chen Xiuyuan's Medical Works remain in print to this day.

This tooth formula is one of the gems distilled from his lifelong clinical experience.

Original text from the classical record:

"Grind all ingredients into a very fine powder. Each morning after washing the face, rub the teeth with the powder, then rinse repeatedly with water and spit it out. This formula treats a great many dental complaints. In the past, a man over forty suffered from severe tooth disease and had lost three molars. He met the younger brother of Chancellor Lu Nanshi of Dezhou, who passed on this formula. After using it, his loose teeth became firm again, and all tooth troubles vanished. Even when eating hotpot, fried, and scorched foods in winter, his gum bleeding and swelling no longer troubled him."

In just over a hundred characters, the text tells of a real clinical case: a man in his forties, having already lost three molars, used this powder to stabilize the rest — and even winter hotpot no longer triggered bleeding or swelling.

II. Guchi Shenfang | Complete Formula & Ingredient Guide

Complete Formula

Preparation: Grind all herbs into an extremely fine powder. Sift through a fine mesh. Store in a glazed ceramic jar, sealed and protected from light. Keeps indefinitely.

Nine Herbs, Each with a Distinct Role

The brilliance of this formula lies in its simultaneous attack and tonification — treating both root and branch:

Qingyan + Shigao (the "cleansing duo"): Salty-cold, clear stomach fire, firm teeth, stop bleeding. These are the "cleaners" of the formula.
Buguzhi + Hanliancao (the "root tonifiers"): One warms Yang, the other nourishes Yin — both act on the Liver and Kidney. In TCM, the Kidney governs the bones, and the teeth are the surplus of bone. This is the key to lasting results.
Huajiao + Xixin + Baizhi + Fangfeng (the "pain-relief squad"): Four pungent, warm herbs that directly attack toothache, gum swelling, and cold-triggered pain.
Nan Bohe (the "freshener"): Clears the head, freshens breath, balances the formula's intensity.

⚠️ Three Critical Reminders

Qingyan ≠ Table Salt. Qingyan is natural rock/halite salt, cold in nature. Refined table salt lacks its mineral profile and therapeutic effect.
Huajiao must be "de-eyed." The "mu" (eyes) are the dark seeds inside the peppercorn husk. Leaving them in irritates oral mucosa. Explicitly instruct your herbalist to remove them all.
Xixin is potent — never self-adjust the dose. Xixin is a key toothache herb but contains aristolochic-acid-related compounds in some species. The formula's Shigao and Qingyan (both cold) balance its warmth. Never increase the dose on your own.

III. Standard Usage Protocol (Save This Section)

Basic Protocol (Daily Must-Do)

Advanced Protocol (After Every Meal)

After each of the three daily meals, rinse your toothbrush with clean water — no toothpaste — dip into the powder, brush the gumline, hold for 5 minutes, then rinse.

Expected results: Most users notice reduced gum bleeding and less tooth sensitivity within 3 days to 1 week.

Additional Note

Some users report passing substantial old stool in addition to dental improvements. The folk explanation: tiny amounts of powder, not fully rinsed away, are swallowed with saliva. The warm-pungent herbs (Xixin, Huajiao) then gently warm the intestines and promote bowel movement — an unintended bonus.

IV. Real-World Practice Notes (User Testimony)

In early January 2010, a friend who had suffered chronic recurrent toothache for years asked a pharmacy to prepare this formula according to the original recipe. After more than a year of consistent use, he hand-wrote his experience and sent it to me. With gratitude, I share his notes:

Method: Every night before bed, after cleaning the teeth, dip the toothbrush in "Guchi Powder" and rub along the gums. Hold the medicine in the mouth for ten minutes, then rinse with water and spit out.

✅ Effect 1: Prevents gum recession and periodontal disease; relieves toothache. ✅ Effect 2: Extends the lifespan of both natural teeth and dentures.

Personal record: After more than one year of continuous use, this formula proved genuinely effective. Originally plagued by frequent toothaches, I experienced only two mild episodes during the initial adjustment period — and then no tooth pain at all for a very long time thereafter.

One year. From "frequent episodes" to "pain-free for a long time." This isn't marketing copy — it's the handwritten log of an ordinary user.

V. Who Should Consider This & Safety Precautions

✅ Suitable For

People with frequent gum bleeding, redness, or recession
Those with loose teeth or at risk of tooth loss
Individuals with recurrent toothache or sensitivity to cold/heat/sweet/sour
Post-periodontal-treatment maintenance
Anyone wishing to preserve natural teeth and delay extraction

⚠️ Safety Precautions

Closing Thoughts

Teeth are the body's hardest organ — and the most easily taken for granted. We brush every day, yet few ever ask: is brushing merely cleaning, or could it also be nourishing?

What Guchi Shenfang taught me is this: a good set of teeth isn't built by the drill — it's built by gentle, daily persistence.

Nearly two centuries ago, Chen Xiuyuan wrote down this formula rooted in the simplest Chinese wisdom — treat the disease before it arises; the key is consistency. Rather than waiting until the pain keeps you awake at night and a dentist says "let's extract it," why not start today with a way of brushing that actually understands your teeth?

You only get one set of natural teeth. Use them wisely, and cherish them.
