Botanical Description
Curcuma longa L. is a rhizomatous herbaceous perennial in the family Zingiberaceae, reaching about 1 meter tall. It produces a stout, branched, deep orange to yellow underground rhizome composed of a central ovoid primary rhizome and lateral cylindrical secondary rhizomes. Leafy shoots arise from the rhizome and consist of long-petioled, oblong to elliptic-lanceolate leaves 30 to 45 cm long with parallel venation and a pointed tip. The inflorescence is a dense, cylindrical spike 10 to 15 cm long borne on a central scape, bearing pale green, often pink-tipped bracts that subtend small, pale yellow flowers with a darker yellow labellum. Native to the Indian subcontinent and Southeast Asia, turmeric is cultivated extensively across tropical regions for its rhizome, which is boiled, dried and ground to a deep orange powder. In Chinese medicine the rhizome is called Jiang Huang and is regarded as acrid, bitter and warm, invigorating blood and moving qi.

Cultural & Historical Context
Traditional Chinese Uses
Jiang Huang (turmeric rhizome) is a pungent, bitter, warming herb with a well-established reputation in Chinese medicine for moving Blood and Qi to alleviate pain. It is particularly indicated for shoulder and arm pain caused by Wind-Cold-Damp obstruction, menstrual pain resulting from Blood stagnation, and chest or abdominal pain from Qi and Blood obstruction. Applied topically, turmeric appears in classical formulas for traumatic swelling and certain skin conditions.
Traditional American Uses
Hawaiian herbalists used Curcuma longa as a blood medicine, pounding bulbs, shoots and other plants together and squeezing them to take the resulting liquid to cleanse the blood (Akana 1922, Hawaiian Herbs of Medicinal Value, p. 33). Bark and other plants were similarly pounded, squeezed and the resulting liquid taken for nose odors, and the bulbs with other plants were pounded so that the fumes from the squeezed liquid could be inhaled for nose growths or odors (Akana 1922, p. 33). The same preparation of bark and other plants was used as a gargle as an oral aid (Akana 1922, p. 33).
