Turmeric Essential Oil
Curcuma longa
Turmeric essential oil is steam distilled from the roots and rhizomes of Curcuma longa, and ours comes from organically grown plants in India. The aroma is warm and radiant, earthy and spicy, and it settles in as a base note.
The chemistry is dominated by ketones, which average about 57% of the oil. The biggest one is ar-turmerone, typically 28-34% in our batches, with α-turmerone alongside it in a wider range of roughly 6-22%. Sesquiterpenes like α-zingiberene fill out the rest. This is the profile Turmeric is loved for in aromatherapy: anti-inflammatory and analgesic in character, well suited to soothing everyday aches and discomfort, with an uplifting, mood-supporting side too.
Every batch we bring in is independently GC-MS tested, and you can read the full report for each one right here on this page.

Batch TUM-111 was steam distilled in March 2026 from the rhizomes of organically grown turmeric (Curcuma longa) in India. The rhizome is the thick underground stem of the plant, the same part that is dried and ground for the kitchen spice. The oil is a clear yellow to orange liquid with a warm, earthy, spicy aroma and a soft woody note. Its color is rich enough to mark light fabrics, so protect your clothing when you blend with it. An independent laboratory tested this batch by GC/MS. The full report and the certificate of analysis are available to download on this page, and the Chemistry Highlights describe what the report shows. This batch has a shelf life of five years, to March 2031, when it is stored cool, dark and tightly closed.
Chemistry highlights
Turmeric oil is known for its turmerones, a group of sesquiterpene ketones, and they lead this batch. ar-Turmerone is the largest at 26.62%, with α-turmerone at 8.78%, β-turmerone at 4.25% and a further turmerone isomer at 9.38%. Together they make up about 49% of the oil, and ketones as a family total 52.47%. Compared with our four most recent earlier batches (TUM-107 to TUM-110), this one holds a little less of the turmerones and a little more of the sesquiterpenes. In those batches ar-turmerone measured 29.46% to 34.02% and α-turmerone 11.96% to 21.89%. ar-Curcumene is higher here at 7.77% (earlier batches 4.17% to 6.15%), and α-zingiberene is 5.44%. Sesquiterpenes total 25.77%. ar-Curcumene, α-zingiberene, β-sesquiphellandrene (2.83%) and β-bisabolene (1.86%) are close relatives of the turmerones. They share the same carbon frame, called the bisabolane skeleton. Monoterpenes are a small part of this oil at 1.45%, including 1,8-cineole at 0.39%, so the aroma stays deep and warm. In a blend, a profile like this may feel warming and comforting, and many people choose turmeric oil for muscles and joints after effort. Use a low dilution on the skin. The laboratory named 67 components and recorded three small unidentified peaks, 2.03% together.
