Why do they contain ethanol?
The ethanol is just used as the preservative and it's used in a very minimal amount. All flower essences, herbal and homeopathic preparations contain a form of alcohol as their preservative and I have chosen ethanol for mine as it is less reactive (ie. no gluten) and milder in taste (most essences use brandy which has a strong taste). It is the safest and purest way to preserve the flower essence. Should you have any questions about the effects of minute amounts of alcohol in your given situation please consult a medical professional. Likewise if you have any concerns about taking them in addition to prescription medicine also speak to your doctor.
