The *Duanju Fang* (Short Drama Formulas) treats the condition of bleeding from behind the teeth after drinking to intoxication, where blood gushes out uncontrollably: Take a small iron nail, heat it until red-hot, and press it directly onto the bleeding pore; this will stop the bleeding.

The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: Teeth are the end of the bones and are nourished by marrow. If the marrow is weak and the bones deficient, wind pathogens invade, leading to loose teeth.

The *Yangsheng Yaoji* (Essentials for Health Preservation) states: To treat toothache caused by eating acidic fruits: Hold white honey in the mouth and chew it; recovery is immediate.

The *Qianjin Fang* (Prescriptions Worth a Thousand Gold) treats gingival pain that prevents eating raw fruits:
Sheng Dihuang (Raw Rehmanniae Radix) Guixin (Cinnamon Twig)
Chew these two ingredients together until their flavors blend, then swallow.

The *Zhubing Yuanhou Lun* states: Bruxism (Xiechi), also known as grinding teeth during sleep, refers to the friction and biting of upper and lower teeth while sleeping. This occurs due to deficiency of blood and qi, with wind pathogens lodging between the tendons and vessels of the masseter muscle; thus, breathing during sleep causes audible sounds.

The *Luyuan Fang* (Verified Record Formulas) treats bruxism: Have the person take soil from under their sleeping mat and place it in their mouth without their knowledge.

The *Zhubing Yuanhou Lun* states: Hou Bi (Sore Throat/Throat Obstruction) involves swelling, blockage, and bi-sensation pain in the throat, making it impossible to swallow water or fluids. Wind-toxins lodge in the throat, causing qi stagnation and accumulation, which generates heat and leads to throat obstruction.

The *Ge Shi Fang* (Ge's Formulas) treats severe Hou Bi where fluids cannot be swallowed, which can be fatal within seven to eight days. The treatment is as follows:
Alongside the affected side (left or right), prick the posterior half of the nail bed of the thumb with a knife blade until blood flows; this brings cure. (Current verification: The *Longmen Fang* states...)

Another formula: Prick beneath the nail of the little finger on either side of the disease, allowing blood to flow; recovery is immediate. First, bind the finger tightly to gather blood, then prick.

Another formula: Roast Apricot Kernels (Xingren), form into pills the size of bullet seeds using honey, hold in the mouth, and swallow the juice.

The *Duanju Fang* treats sudden Hou Bi resulting in aphonia: Decoct Cinnamon Juice (Guizhi Zhi) strongly and drink 1 sheng; cover the body to induce sweating. Alternatively, powder Cinnamon Twig (Guixin) and place it under the tongue; this is highly effective.

Another formula: Take the grate from a steamer, burn it to ash, take an amount held by three fingers, mix with a little water, and drink; effect is immediate.
