Botanical Description

Curcuma phaeocaulis (zedoary, dark-stemmed turmeric) is a robust herbaceous perennial in the Zingiberaceae family, native to subtropical southern China and Southeast Asia, growing 0.9-1.5 m tall from a stout, branching rhizome. The rhizome is large, conical to ovoid, with a grey-brown corky outer surface and a pale yellow to bluish-grey, camphoraceous-smelling, bitter-pungent flesh. The pseudostem, formed by overlapping leaf sheaths, bears 4-7 elongate-lanceolate to oblong leaves 30-60 cm long with a purplish-brown stripe along the midrib. The inflorescence emerges separately from the rhizome before or with the leaves, as a dense cylindrical spike of green bracts tipped with pink to rose-purple coma bracts; the small yellow tubular flowers are nested between the green bracts (POWO; Wikipedia).

Cultural & Historical Context

Traditional Chinese Uses

E Zhu (zedoary rhizome) is a warm, pungent herb that breaks Blood stasis and moves Qi, making it one of the stronger herbs for addressing fixed abdominal masses, tumors, and severe menstrual pain from Blood and Qi stagnation. It also dissolves food stagnation and resolves the accumulation of old, hardened masses. Because of its forceful breaking action, it is used cautiously in debilitated patients and is contraindicated in pregnancy.
