大枫子（三钱） 人言（一钱，即砒霜） 核桃仁（三钱） 水银（一钱）
研磨成细末，制成六丸。晚间在心窝处，用一丸用手旋转摩擦，一夜使用一丸。病情轻者使用三至四丸即可痊愈，病情重者再配制一料也可痊愈。
阴虚导致的双蛾（扁桃体红肿如双蛾状），方剂用法如下：
附子（一钱），用盐水炒制，每次取一片含在口中，随后大量饮用六味地黄汤。
外治法：
引火下行，用一个附子研为粉末，用醋调和，贴敷于涌泉穴。或者使用吴茱萸一两、白面五钱，用水调和，贴敷于涌泉穴。急刺少商穴，则咽喉就会有一线通畅之路了。
防风（五分） 硼砂（一厘） 胆矾（二厘半）

[External Treatment Methods for Skin Diseases]: For conditions with mild pathogenic invasion, where the disease has not deeply penetrated the Ying (Nutrient) and Wei (Defensive) levels [Ying-Wei: The Nutrient level refers to the blood and fluids circulating within the vessels, while the Defensive level refers to the Qi circulating outside the vessels], treatment should be directed from the skin and hair. Such conditions as scabies [Scabies: A contagious skin disease caused by mites], huangshui chuang [Huangshui Chuang: A skin condition characterized by weeping yellow fluid], and fei chuang [Fei Chuang: Heat rash or prickly heat] do not require decoctions. For scabies, use:
Da Feng Zi (Semend Cerebrum, 3 qian) Ren Yan (Arsenic Trioxide, 1 qian) Tao He Ren (Semen Persicae, 3 qian) Shui Yin (Mercurius, 1 qian)
Grind into a fine powder and form six pills. In the evening, apply one pill to the epigastrium [Epigastrium: The upper central region of the abdomen] and rotate it with the hand, using one pill per night. For mild cases, three to four pills will suffice for recovery; for severe cases, another dose may be prepared and used until cured.
For Yin deficiency presenting as Shuang E [Shuang E: Bilateral tonsillar hypertrophy resembling two silkworms], use the following prescription:
Fu Zi (Radix Aconiti Lateralis Preparata, 1 qian), stir-fried with salt water. Use one slice at a time, holding it in the mouth, followed by drinking a large dose of Liu Wei Di Huang Tang [Liu Wei Di Huang Tang: Six-Ingredient Pill with Rehmannia].
External treatment method:
To guide fire downward, take one Fu Zi, grind it into powder, mix with vinegar, and apply to Yongquan [Yongquan: Kidney 1, located on the sole of the foot]. Alternatively, use Wu Zhu Yu (Fructus Evodiae, 1 liang) and Bai Mian (Tritici aestivi Farina, 5 qian), mix with water, and apply to Yongquan. Urgently needle Shaoshang [Shaoshang: Lung 11, located at the radial corner of the thumbnail]; this will open a narrow passage in the throat.
Fang Feng (Radix Saposhnikoviae, 5 fen) Peng Sha (Borax, 1 li) Dan Fan (Alumen, 2.5 li)
Decoct together and wash the affected area with the liquid; immediate cure is achieved.
This prescription originates from Dao Zang [Dao Zang: The Taoist Canon]. Regardless of blindness [Gu Mu], eye diseases caused by exposure to earth/dust [Fan Tu], visual obstruction by clouds/fog [Yun Wu], wind-eye [Feng Yan], fire-eye [Huo Yan], or blurred vision [Hun Hua], long-term washing will restore clarity. [Prescription] Usage:
Pi Xiao (Natrii Sulfas, 6 qian) Sang Bai Pi (Cortex Mori Radicis, 1 liang)
Decoct in water.
Wash repeatedly with hot water on specific auspicious dates: the 5th day of the first lunar month, the 2nd day of the second month, the 3rd day of the third month, the 9th day of the fourth month, the 5th day of the fifth month, the 4th day of the sixth month, the 3rd day of the seventh month, the 10th day of the eighth month, the 12th day of the ninth month, the 12th day of the tenth month, the 4th day of the eleventh month, and the 4th day of the twelfth month.
These are days when auspicious stars shine, symbolizing universal illumination. This prescription is worth a thousand gold and never changes; it has proven effective repeatedly.
Xiao Hong Zao (Fructus Jujubae, 12 pieces, washed clean with cold water and pitted) Gan Gou Qi (Fructus Lycii, 3 qian) Ma Liao Dou (Semen Sojae, 4 qian)
Add two bowls of water, decoct until one bowl remains. Consume the residue and broth together on an empty stomach in the morning.
Use Sheng Gan Cao (Radix Glycyrrhizae, 3 liang), decoct in water to make a soup. Add half a bowl of Yang Xue (Sanguis Ovis), mix well, and drink. Immediate vomiting will lead to recovery. If vomiting does not occur after ingestion, immediately use:
Da Huang (Radix et Rhizoma Rhei, 2 liang) Gan Cao (Radix Glycyrrhizae, 5 qian) Bai Fan (Alumen, 1 liang) Dang Gui (Radix Angelicae Sinensis, 3 liang)
Decoct in water to make several bowls of soup and drink. Immediate profuse vomiting will ensure survival.
