Is this zedoary turmeric oil 100% natural and undiluted?
Yes. This zedoary turmeric oil is 100% natural and undiluted, produced by steam distillation directly from dried Curcuma rhizomes with no carrier oil, no synthetic sesquiterpenes, no solvents added and no blending for price purposes. Each batch is released with an HPLC fingerprint that confirms natural origin and composition.
Purity Guarantee
| Check | Method | What it proves |
|---|---|---|
| HPLC fingerprint | 216 nm, C18 column | Similarity ≥0.95 with reference — natural identity |
| Germacrone / furanodiene | HPLC quantification | Real rhizome content, not synthetic dilution |
| GC profile | GC-FID | Natural distribution of sesquiterpenes |
| TLC identification | Pharmacopoeia method 0502 | Curcumol, germacrone, curdione present |
What We Never Add
- No synthetic germacrone or curcumol fortification
- No carrier oil, mineral oil or vegetable oil cut
- No solvent residue (extraction is steam-based; CO2 grade uses food-grade carbon dioxide)
- No synthetic antioxidants added; natural stability comes from the sesquiterpene profile
Verification For Buyers
- Ask for the batch COA and the HPLC fingerprint attachment
- Check that the GC pattern shows the full natural range of sesquiterpenes rather than a few sharp synthetic peaks
- Independent third-party testing (GC-MS) can be arranged and paid by mutual agreement
- Retained samples are kept for 24 months for any future comparison
