No, the data are based on the average % of each substance for all uploaded analyses of a single oil

They come from our daily activity as an essential oil testing and R+D laboratory. Each single characterization analysis which has passed the Authentication and quality control is uploaded to CHROM-DB

Yes, new batches are continuously uploading for averaging, new oils added, updating IFRA standards, etc

Each report is internally linked to several analyses of different lots and/or suppliers, each one with a different ID number. Those interested in the traceability of a particular oil can make an inquiry through our contact page.

Not all of them. There are oils relatively new in the industry which are still in process of standardization. Please check our post about essential oils standardization

Many of the specifications are established considering a compendium between international standards and our own statistical data. Others are set using only our historical data, due to the lack of standards. In addition, there may be oils without specifications (non-standardized oils)

Our phytotherapy specialist is compiling literature to assign the activity to each single substance. All the biological activities are based on meta-analyses, reviews, in-vivo and in-vitro studies. The activity of the oil is calculated from its chemical composition. Please note that the synergistic effect between substances has not been taken into account in this distribution

In some cases, the oil marketed in the industry is a blend of several geographical origins or chemotypes.

The last published at

Only some rare unknown compounds (normally traces) or low volatile (heavy compounds) such as certain furocoumarins, are not present in the reports. The essential oils are major composed by volatile substances but sometimes the non-volatile content is higher than usual, as with certain absolutes.
