Dose:
1. Traditionally, some sources regarded the head as toxic, and therefore ordered it to be removed. Other texts stated the head was the strongest part. In some cases the head and/or tail were used for specific conditions. Today, the whole dried Centipede with head is used for all functions.
2. When used in Decoction, it is best to take the powder with the decoction rather than decocting the Centipede.
Powder: 500mg–2, or 2.5 grams.
Decoction: 1.5–4.5 grams
It may be applied topically with vinegar or wine in the form of a paste.
Comment:
Scorpion and Centpiede are similar in use and often used together. Scorpion is regarded as strionger for Twitching and Tremors while Centipede is stronger for Spasms, Convulsions and Toxic Swellings.
Preparation:
1. Legs are removed, usually the head also. It is often gently dry-fried until yellow.
2. It may be stir-fried with a little alcohol to make is stronger to move the Blood and clear obstructions
3. Sometimes, they were dry-fried with Mint leaves.
Corrective:
1. Rose
2. Tabasheer
Substitute:
1. Indian leaf (Cinnamomum tamala)
2. Ambergris
Tests for Musk
1. Real musk is soft to touch and the fake is hard.
2. By putting a grain of Musk on a coal fire, if they melt and bubble, it is genuine, if they immediately harden to ashes, it is fake.
Main Combinations:

4. Hemiplegic paralysis caused by stroke:
i. Centipede (Wu Gong) with Scorpion (equal parts as a powder; clinically proven effect)
5. Tetanus:
i. equal parts of Centipede (Wu Gong) with Scorpion, Aconitum Fu Zi, Aconitum Wu Tuo. Dose was 30–60mg, and the powder is also applied to the wound. “Once the patient sweats he will be cured” (Wu Gong San from Ru Men Shi Qin [How the Literati Care for Their Parents]).
ii. Tetanus-induced limb spasms, Lockjaw, Centipede (Wu Gong) with Arisema bile-prepared (Dan Nan Xing), Saposhnikovia Fang Feng, and River-fish Swim bladder (Jiang Bao) (as in Wu Gong Xing Feng San from Yi Zong Jin Jian [Golden Mirror of Orthodox medicine]).
6. To move the Blood and resolve masses:

10. Herpes Zoster, topically as a paste, Centipede (Wu Gong) with Coptis Huang Lian, Borneo Camphor (Bing Pian)
11. Painful Piles:
i. Centipede (Wu Gong) baked and powdered, add a little Borneol, mix with saliva to form a paste which apply. (Zhi Zhi Fang)
ii. “soak 3 to 4 Centipedes in Sesame oil, boiled once or twice to bubbling, and then add two to three qian of Chinese
Gallnut powder. This is to be stored closely sealed in a jar. If one happens to encounter an unbearable pain, he is to drip the oil on and the pain will end immediately. Very effective”. (Sun Shi JI Xiao)

Hemolytic effects cause brown urine, black stool, and hemolytic anemia usually follows. Overdose has been associated with Liver dysfunction and acute renal failure. Therefore, dosage should be strictly adhered to. Long-term use should be avoided, or a break in treatment every 2–3 weeks. Periodic Liver and Kidney function tests could be indicated with long-term use, or in the elderly, or those susceptible to Liver and Kidney dysfunction.
4. Allergic reactions may include rash and anaphylactic shock in severe cases.
Antidotes:
1. Tea
2. Decoction of Feng Wei Cao (phoenix-tail fern), Honeysuckle Flower (Jin Yin Hua), and Licorice.
