Two new species of Curcuma, C. sattayasaii A. Chaveerach ＆ R. Sudmoon and C. zedoaroides A. Chaveerach ＆ T. tanee with rhizomes traditionally used for many decades as cobra-bite antidotes are described and illustrated. Curcuma sattayasaii is similar to C. longa L., but differs in rhizome horizontally branching on ground; coma bracts pinkish-white or pinkish-pale green; corolla pale yellow with orange tip; labellum pale orange with an orange central band; anther crest very short, broadly ovate, wider than long. Curcuma zedoaroides is similar to C. zedoaria （Christm.） Roscoe, but differs in rhizome branching pattern; the protruding secondary rhizomes curved down; blades oblong to oblong-lanceolate; peduncle glabrous; fertile and coma bracts glabrous; corolla lobes pale yellow to white, lateral lobe ovate, dorsal lobe broadly ovate. The new taxa have been found in a village of Khon Kaen Province, Northeastern Thailand.
