At PhytoChemia, we always like to seek around us to find interesting plants to distill. This summer, we performed several distillations of different plants. You will find in this blog post a summary of our 2018 summer distillations along with the general composition of essential oils that we obtained, their yields and some other interesting informations. Enjoy our results and feel free to share them with your friends!
