Bests & Worsts Reviews from Amazon

I was really excited to get these oils since 750 reviewers gave it excellent marks. I put the lavendar oil in my diffuser and started having a very bitter taste in my mouth and started getting a headache, which lavendar has never done to me before. I tried to look on their website for information on the ingredients, and website kisoil.com that they wrote on the bottles IS NON-EXISTENT. That really scared me because they don't have any information on the bottles, no pamphlet in the box and no website. Therefore they cannot be liable for any harmful chemicals found in this product. And I cannot return them because according to Amazon it is considered hazardous material. If I were you, I would buy essential oils from a company that has available information on it's product!!!
