About This Herb*
Traditional Chinese Medicine background and properties
Herb Description*
Centipede is a potent animal-based substance used in Chinese medicine primarily to stop spasms and convulsions, relieve severe or stubborn pain, and break up toxic swellings. Because it is toxic, it is always used in small, carefully measured doses under professional supervision. It is especially valued for conditions that resist ordinary treatment, such as chronic headaches, post-stroke paralysis, and deeply lodged joint pain.

Main Actions*
- Extinguishes Wind and Stops Spasms
- Unblocks the Channels and Alleviates Pain
- Resolves Toxicity and Dissipates Nodules
How These Actions Work*
Extinguishes Wind and stops spasms (息风止痉): Wu Gong has a powerful ability to calm internal Liver Wind, the TCM concept that explains involuntary movements like tremors, spasms, and convulsions. Its pungent, warm, and strongly penetrating nature allows it to quickly suppress spasmodic activity. This is the primary reason it is used in conditions involving seizures, childhood convulsions, tetanus, and epilepsy. It is considered stronger than its common partner Quán Xiē (scorpion) for this purpose.
Unblocks the collaterals and stops pain (通络止痛): As an insect-type substance, Wu Gong has a uniquely powerful ability to bore into and open up blocked channels and collaterals (the fine network of pathways in the body). This makes it especially effective for stubborn, deeply lodged pain that ordinary herbs cannot reach, including chronic joint pain from Wind-Damp obstruction, post-stroke numbness and paralysis, and severe, recurrent headaches or migraines.
Attacks toxin and dissipates nodules (攻毒散结): Wu Gong uses its own toxic nature to counteract other toxins in the body, a principle known in TCM as 'using poison to attack poison.' It can break apart toxic accumulations such as abscesses, scrofula (lymph node swellings), carbuncles, and venomous snake bites. Modern clinical use has extended this action to include certain tumors and cancerous growths, where it is used alongside other anticancer herbs.
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Wu Gong is traditionally associated with these specific patterns.
The following describes this herb's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Wu Gong addresses this pattern
Wu Gong enters the Liver channel with a pungent, warm, and strongly penetrating nature. Liver Wind stirring internally causes involuntary movements such as spasms, tremors, and convulsions. Wu Gong's powerful wind-extinguishing action directly suppresses this internal Liver Wind. Its nature as an insect substance gives it a rapid, burrowing quality that reaches deep into the body to calm the agitation. It is one of the strongest substances available for this pattern, often paired with Quán Xiē (scorpion) and Jiāng Cán (silkworm) for enhanced effect.
A practitioner would look for one or more of these signs
Convulsions and seizures from Liver Wind
Epileptic episodes
Spasms, lockjaw, opisthotonos
Childhood convulsions or tremors
Why Wu Gong addresses this pattern
In Wind-Damp Painful Obstruction (Bì syndrome), pathogenic Wind, Cold, and Dampness lodge in the channels and joints, causing pain, stiffness, and numbness. Wu Gong's pungent taste disperses Wind, while its warm temperature scatters Cold. As an insect substance with a powerful boring and penetrating quality, it excels at unblocking collaterals that have been obstructed for a long time. This makes it especially useful for stubborn, chronic joint pain that ordinary wind-dispelling herbs cannot resolve.
A practitioner would look for one or more of these signs
Chronic joint pain and stiffness
Numbness and restricted movement of limbs
Stubborn, deeply lodged pain unresponsive to other treatments
Why Wu Gong addresses this pattern
When toxic Heat accumulates and forms visible swellings such as sores, abscesses, or scrofula, Wu Gong can attack the toxin and break apart the nodule. Its own mildly toxic nature is harnessed therapeutically to counteract the pathogenic toxin, a classical principle of 'using poison to fight poison.' Its pungent, dispersing quality helps dissipate the hardened mass, while its channel-opening ability ensures the toxin can be expelled. It is used both internally and as a topical powder for abscesses and venomous bites.
A practitioner would look for one or more of these signs
Toxic sores and abscesses
Scrofula and lymph node swellings
Venomous snake bites
