Chuan Po Shi Root Classic Formulas … Natural Herb Library

Primary Actions

Dispels wind-damp and unblocks the channels ... Chuan Po Shi is a regional root medicine for rheumatic pain, lower-body soreness, and lingering obstruction with swelling or stiffness.
Clears damp-heat and relieves jaundice ... southern folk use repeatedly places it in formulas for yellowing disorders, turbid damp accumulation, and heat lodged in the Liver-Gallbladder axis.
Resolves toxicity and reduces swelling ... it is applied to boils, abscesses, and inflamed lesions when heat, toxin, and local stasis combine.
Moves Blood and relieves traumatic pain ... the root appears in injury and fracture traditions where bruising, fixed pain, and collateral obstruction need a penetrating root rather than a gentle tonic.

Regional jaundice and hepatitis decoctions with Yin Chen, Ji Gu Cao, or Tu Fu Ling ... common southern pairing logic when damp-heat and swelling dominate.
Trauma and painful-obstruction combinations with Ji Xue Teng, Niu Xi, or Ru Xiang ... used when bruising, channel blockage, and rheumatic soreness overlap.
Heat-toxin and swelling formulas with Pu Gong Ying or Jin Yin Hua ... a traditional extension of the root's detoxifying and swelling-reducing role.

Lingnan herb traditions classify Chuan Po Shi among roots that clear heat, dispel dampness, open the collaterals, and reduce painful swelling.
Older regional herb descriptions also connect it with jaundice, traumatic injury, and stubborn rheumatic pain rather than with mainstream tonic use.
