Overview

Lavender is an herb. The flower and the oil of lavender are used to make medicine.

Lavender is commonly used for anxiety, stress, and insomnia. It is also used for depression, dementia, pain after surgery, and many other conditions, but there is no good scientific evidence to support many of these uses.

In foods and beverages, lavender is used as a flavor component.

In manufacturing, lavender is used in pharmaceutical products and as a fragrance ingredient in soaps, cosmetics, perfumes, potpourri, and decorations.

Lavender (scientific name Lavandula angustifolia) is commonly contaminated with related species, including Lavandula hybrida, which is a cross between Lavandula angustifolia and Lavandula latifolia, from which lavandin oil is obtained.

Classification

Is a Form of:

Herb

Primary Functions:

Anxiety, stress, insomnia

Also Known As:

Alhucema, Common Lavender, English Lavender, French Lavender

How Does It Work?

Lavender contains an oil that seems to have sedating effects and might relax certain muscles. It also seems to have antibacterial and antifungal effects.

Uses

• Anxiety. Limited research shows that taking lavender oil by mouth might improve symptoms in some people with anxiety. It's unclear if lavender aromatherapy improves anxiety. Some research shows benefit, while other research does not.
• Depression. Research shows that lavender aromatherapy may improve symptoms in some people with depression. Taking lavender by mouth might also help. While taking lavender appears to be slightly less effective than the antidepressant drug imipramine, taking the two in combination might be more beneficial than taking the drug alone.
• Menstrual cramps (dysmenorrhea). Lavender oil aromatherapy massages reduce pain associated with menstruation in some young women better than regular massages. Also, inhaling lavender oil for the first 3 days of menstruation seems to reduce stomach pain and backache in women with menstrual pain.
• Pain after surgery. Some research shows that inhaling lavender essence while receiving pain killers intravenously (by IV) can help reduce pain in women after a C-section. Other research shows that inhaling lavender for 3 minutes every 6 hours can lessen pain and reduce the need to use acetaminophen after a tonsillectomy in children 6-12 years old.

Recommended Dosing

The following doses have been studied in scientific research:

ADULTS

BY MOUTH:

• Anxiety: 80-160 mg of a specific lavender oil ingredient (Silexan, Dr Willmar Schwabe GmbH & Co. KG) has been taken daily for 6-10 weeks. 500 mg of dried, powdered lavender flowers has been taken twice daily for 8 weeks.
• Depression: 80 mg of a specific lavender oil ingredient (Silexan, Dr Willmar Schwabe GmbH & Co. KG) has been taken daily for 6 weeks. 60 drops of a diluted lavender tincture have been taken daily for 4 weeks.

INHALED AS AROMATHERAPY:

• Anxiety: 8 drops of an oil blend containing 2% lavender and rose essential oil has been applied to a cotton pad and inhaled for 15 minutes twice weekly for 4 weeks. The lavender and rose oil formulation was prepared by diluting 2 drops of an essential oil blend containing 75% lavender oil and 25% rose oil diluted in 5 mL of jojoba oil. 3 drops of lavender essential oil has been applied to a cotton pad and inhaled for 5 minutes daily for 1 month. 2 drops of lavender oil have been applied to a cotton pad and kept by the pillow overnight for 1 week. 3 drops of lavender oil have been applied to on a cotton pad and inhaled 30 minutes. Lavender oil has been diffused through a waiting room for 15 minutes.
• Depression: 8 drops of an oil blend containing 2% lavender and rose essential oil has been applied to a cotton pad and inhaled for 15 minutes twice weekly for 4 weeks. The lavender and rose oil formulation was prepared by diluting 2 drops of an essential oil blend containing 75% lavender oil and 25% rose oil diluted in 5 mL of jojoba oil. 5 mL of an aromatherapy oil containing lavender, sweet orange, and bergamot has been massaged into the upper body twice weekly for 8 weeks.
• Menstrual pain: Applying 3 drops of lavender oil to the hands and inhaling every 6 hours or placing 3 drops of oil onto a piece of cotton and inhaling for 30 minutes daily for the first 3 days of menstruation has been used. Also, 2 mL of lavender oil applied on the abdomen for 15 minutes as part of an aromatherapy massage has been used during a menstrual period.
• Pain after surgery: Two drops of 2% lavender essence has been applied to the inside of an oxygen face mask and inhaled for 3 minutes at 3, 8, and 16 hours after receiving pain-relievers for C-section pain.
