International Symposium on Essential Oils (ISEO) has been organized every year since 1969 in a different European town.


ISEO 2021 Programme & Abstract Book has been published.

Welcome to ISEO 2021

Important Announcement

Dear ISEO Permanent Scientific Committee Members,
Dear ISEO Participants,
Dear ISEO Sponsors,

We hope in the covid period that all of you and your families and friends are doing well, safe and all are healthy…

We heartily thank you for all your feedback and guidance.

As you know, we have prepared initially for a “normal- physical” ISEO, since 2019… and we really hoped that the situation would be suitable in 2021 August, scheduled time for ISEO. However, today we are talking about the 3rd wave of covid, which forces us to an online-ISEO with a professional team. Thus, this has many drawbacks including finance, however, nothing is more important than the safety of all ISEO participants. With the agreement of the ISEO Permanent Committee we have decided on the new dates of the 51st ISEO as November 12-14, 2021

The symposium even online has associated costs as previously mentioned, however, the finance shall not be a hindrance for those who lack financial resources, we shall ask sponsors for support.

Our university is supporting online national and international symposia/congresses and meetings, which I hope for other institutions as well.

We will soon make regular mailings and ask your continuous feedback and suggestions for the improvement of services and the symposium program. Also your advice regarding potential sponsors will indeed help for the overall quality of the meeting.

Stay well safe and healthy… kind regards

Prof. Dr. K. Hüsnü Can Başer
President, ISEO 2021

ISEO Medal of Honor

Since last year, ISEO Medal of Honor is awarded to a distinguished scientist who has conducted  outstanding research into essential oils and served for the promotion of essential oils as a distinguished field of science. The first medal was bestowed upon late Prof. Dr. Jan Karlsen who was one of the founding fathers of ISEO. The medal is an art work of an artist in Messina, Italy. We are grateful to Merck/MilliporeSigma* for the generous sponsorship of this medal.
