Where does this zedoary turmeric oil come from — plant and origin?
This zedoary turmeric oil (TPS-HO-003) is a Chinese herbal essential oil distilled from the dried rhizomes of E Zhu, the Zingiberaceae (ginger family) plant Curcuma zedoaria (Christm.) Rosc. or Curcuma phaeocaulis Val. (Guangxi zedoary). The rhizome is recorded in the Chinese Pharmacopoeia as Rhizoma Curcumae Zedoariae, one of the three 'Curcuma sisters' together with Yujin and Jianghuang.

TCM Background
- In traditional Chinese medicine, E Zhu is classified as pungent and bitter in taste, warm in nature, acting on the liver and spleen meridians
- Its classic actions are 'moving qi and breaking blood stasis, resolving accumulations and relieving pain'
- Pharmacopoeia-grade raw material is sourced from Dao-di production areas, mainly Guangxi zedoary and Wenzhou wen-ezhu, to guarantee curdione and germacrone content
- Zedoary is frequently paired with Yujin and Jianghuang in formulas, but its oil is distinctly stronger, hotter and more penetrating
