Centipede Classic Formulas — Natural Herb Library

Primary Actions

Extinguishes wind and stops spasms - Wu Gong is one of the stronger animal medicinals for convulsions, tetanus, epilepsy, severe muscle spasm, and stubborn internal-wind disorders, and is traditionally considered more forceful than Quan Xie in this role.
Counteracts toxicity and dissipates nodules - it is classically used for sores, abscesses, scrofula, goiter, and toxic swellings, especially when the lesion is hard, painful, and resistant to milder treatment.
Unblocks the collaterals and alleviates pain - Wu Gong is selected for severe wind-damp arthralgia, numbness, stubborn headache, and post-stroke channel obstruction when ordinary herbs have failed to penetrate deeply enough.
Searches out stubborn, entrenched pathology - its strong penetrating nature makes it a medicine of refractory conditions rather than mild everyday use, whether the target is convulsive wind, painful obstruction, or fixed toxic masses.
