The essential oils of lavender flower and eucalyptus leaf are frequently combined for use in aromatherapy. Lavender oil and eucalyptus may help to relieve depression, anxiety, pain, inflammation and congestion. Eucalyptus and lavender oils are associated with few side effects when they are used as a component of aromatherapy. However, both products are extremely toxic if they are taken internally. Consult your health care provider before using eucalyptus lavender oil if you have a serious medical condition.
Skin Irritation
Some people develop a rash after skin exposure to eucalyptus and lavender oil. This reaction is most common in people with pre-existing allergies to either plant.
Respiratory Irritation
Eucalyptus and lavender are both traditionally used to ease symptoms of cough and asthma. However, these oils may worsen symptoms. People who are allergic to lavender or eucalyptus may develop an irritation of the eyes and nose after exposure to the plants during aromatherapy.
Digestive Problems
Neither lavender oil nor eucalyptus are safe to take internally, even in small amounts. Low doses of either oil can cause diarrhea, severe abdominal pain, vomiting and rectal bleeding.
Poisoning
When taken internally, eucalyptus lavender oil can cause acute poisoning, leading to severe or life-threatening problems. Symptoms of poisoning include dizziness, fatigue, skin discoloration, seizures, difficulty breathing, muscle weakness, slurred speech and blurred vision. Seek immediate medical attention if you experience these symptoms.
