As with many essential oils, do not use if you are pregnant or nursing, or have diabetes. Allergic reactions are possible for those with unusually sensitive skin. Some may experience nausea, vomiting or headaches due to the continual or excessive use of lavender oil.
Most importantly, lavender oil is for topical use only or inhaled through aromatherapeutic means. Ingestion of lavender oil can result in
serious health issues such as blurred vision, difficulty breathing, burning eyes, vomiting and diarrhea.
Be sure to consult with a herbalist or aromatherapist before using this form of alternative treatment.
