Benefits of Lavender Oil for Health
This soothing oil can calm anxiety and improve sleep
Lavender essential oil is one of the most popular and versatile essential oils used in aromatherapy. Distilled from the plant Lavandula angustifolia, the oil promotes relaxation and has clinical research supporting its use as an aid for stress, anxiety, depression, and potentially various other conditions.
Lavender is a multipurpose herb and oil. It is purported to have anti-inflammatory, antifungal, antidepressant, antiseptic, antibacterial, and antimicrobial properties, as well as antispasmodic, analgesic, detoxifying, hypotensive, and sedative effects.
Potential Lavender Oil Benefits
Lavender essential oil and its properties have been widely studied. Here's a look at the research.
- Anxiety
While there's currently a lack of large-scale clinical trials testing lavender's effects on people with anxiety, a number of studies show that the oil may offer some anti-anxiety benefits.
- Reduced Dental Anxiety
Several studies have tested lavender's anxiety-reducing effects in specific populations. For example, a study published in Physiology & Behavior in 2005 focused on 200 people awaiting dental treatment and found that breathing in the scent of lavender both lessened anxiety and improved mood.
- Lavender Supplements May Reduce Anxiety
There's also some evidence that ingesting lavender oil may help relieve anxiety. In a report published in Phytomedicine in 2012, for instance, scientists analyzed 15 previously published clinical trials and concluded that dietary supplements containing lavender oil may have some therapeutic effects on patients struggling with anxiety and/or stress.
- Insomnia
Several studies have shown lavender essential oil may help promote sleep and fight insomnia.
A 2015 study published in the Journal of Complementary and Alternative Medicine found a combination of sleep hygiene techniques and lavender essential oil therapy helped college students get a better night's sleep than sleep hygiene alone. The study of 79 students with self-reported sleep problems also found inhaling lavender at bedtime improved daytime energy and vibrancy.
A 2018 study published in Holistic Nursing Practice confirms lavender's effect on sleep. In this study of 30 residents of a nursing home, lavender aromatherapy was found to improve sleep onset, quality, and duration in an elderly population.
- Depression
Some research suggests that lavender oil may help improve mood and alleviate symptoms of depression. A 2020 systematic review found that aromatherapy utilizing lavender oil could be a simple and inexpensive way to help improve symptoms of mild to moderate depression.
Lavender Oil Dosage and Preparation
There is no recommended daily allowance for lavender essential oil. According to the principles of aromatherapy , breathing in the scent of lavender essential oil or applying lavender essential oil to the skin transmits messages to the limbic system, a brain region known to influence the nervous system and help regulate emotion.
One popular approach involves combining lavender oil with a carrier oil (such as jojoba or sweet almond). Once blended with a carrier oil, lavender essential oil can be massaged into your skin or added to your bath.
Other Lavender Oil Benefits
In addition to the potential mental health benefits of lavender oil, some claim that this essential oil may have other health and wellness benefits.
- Lavender Oil for Allergies
Can lavender essential oil treat allergies? Many essential oil proponents recommend using a combination of lavender, lemon, and peppermint oil to relieve allergy symptoms, and claim that lavender is a natural antihistamine. A 1999 study printed in the J Pharm Pharmaceuticals did find that lavender oil inhibits immediate type allergic reactions in mice and rats.
- Lavender Oil for Eyelashes
Will adding lavender oil to your mascara make your lashes grow faster? Adding lavender oil to mascara is purported to help lashes grow thicker and faster. The theory behind this is that tiny mites live on and feast on eyelashes, inhibiting growth, and using lavender to kill the mites will allow lashes to grow faster. There is no scientific evidence to support this claim.
- Lavender Oil for Hair Growth
Is lavender essential oil a cure for baldness? A few studies over the years have suggested that lavender oil may reverse hair loss. A 2016 study on mice showed that a diluted topically applied lavender essential oil did lead to dramatic hair growth.
An earlier study (1998) looked at people with alopecia areata and showed improvement in hair growth with a topically applied combination of lavender, thyme, rosemary, and cedarwood.
