There are tons of companies which sell "essential oils", here is one company which does it the best. I have been using essential oils for decades, but this is different, it is pure. I am using these since 6 months now and I can say that I have never seen anything purer than these. This is the best you can get and of course at consistent quality lot after lot. I have personally met Shishir Chaturvedi & Shubra Chaturvedi, Father & Daughter team which runs this family owned/ family managed start-up professionally. Eucalyptus Natural & Lavender Natural are my personal favorites & strongly recommended.
