“We often even have an interest in associating the essential oils to an allopathic treatment, explains Danièle Festy, pharmacist and aromatologist. They then allow the treatment to be more quickly effective and better tolerated. In addition, people undergoing chemotherapy can use essential oils of lemon, celery or lovage to support the liver in its role of detoxification (1 drop of celery HE + 1 drop of lemon zest HE on 1 neutral tablet or in ½ teaspoon of olive oil). Aromatherapy is also perfectly compatible withhomeopathy. If you take essential oils with a homeopathic treatment (both orally), you just make sure to always start with the granules, followed 20 minutes later by the drops. The reason: certain essential oils (mint, eucalyptus) have a vasoconstrictor effect. By causing the narrowing of the small vessels located under the tongue, they would prevent the penetration of the homeopathic medicine into the blood.
