Rhizome of Kwangsi Turmeric Classic Formulas … Natural Herb Library

Primary Actions

Breaks up blood stasis and forcefully moves qi ... Guang Xi E Zhu is used for fixed abdominal pain, masses, amenorrhea, and stubborn stagnation patterns where strong movement is needed.
Reduces accumulations and relieves distension ... traditional use includes food stagnation or focal fullness when obstruction and pain travel together.
Relieves pain in traumatic or stagnation-driven patterns ... its action is stronger and more dispersing than the gentler culinary-turmeric image many people assume.

E Zhu with San Leng ... classic pairing for stubborn masses, severe blood stasis, and fixed abdominal pain.
Blood-stasis pain combinations with Dan Shen, Yan Hu Suo, or Dang Gui ... traditional strategy when obstruction and pain are intertwined.
Stagnation and food-accumulation formulas with Shan Zha or Mai Ya ... used when fullness, obstruction, and pain coexist in the middle burner.

Traditional herbology places E Zhu among the stronger blood-invigorating medicinals that break accumulations and relieve pain.
Unlike Jiang Huang, E Zhu is the harsher mass-resolving turmeric-family lane and is used more cautiously in depleted patients.
