Introduction

People usually associate lavender with two specific traits: its fragrance and its color. But you may not know that the lavender flower and the oil derived from it have long histories in herbal medicine.

The word lavender comes from the Latin root “lavare,” which literally means “to wash.” The earliest recorded use of lavender dates back to ancient Egypt. There, lavender oil played a role in the mummification process.

During later times, lavender became a bath additive in several regions, including ancient Persia, Greece, and Rome. These cultures believed that lavender helped purify the body and mind.

Description

Health benefits of lavender
Since ancient times, lavender has been used to reduce symptoms and provide support for multiple conditions. Modern science has confirmed many of its health benefits, while others are still under investigation.

Lavender may help with some of the following:

insomnia
anxiety
hair loss
headaches
chemotherapy side effects
acne
burns
eczema and dry skin
wound healing
mood issues

Data Collection

Insomnia
Once upon a time, lavender was recommended for people suffering from insomnia or other sleep disorders. People stuffed their pillows with lavender flowers to help them fall asleep and get a better night’s rest.

Today, research suggests that breathing in lavender’s aroma could improve sleep quality. A systematic review of 15 studies from 2014Trusted Source found that inhaling essential oils, including lavender, had positive effects in people with mild sleep disturbances.

Numerous smaller studies have found additional benefits of lavender for sleep issues.

Research from 2015 showed that people who used lavender aromatherapy felt more refreshed upon waking. Another 2010 studyTrusted Source conducted on people with anxiety disorders revealed that orally administered lavender oil helped them sleep longer at night.

Results, Outputs, and Outcomes

Anxiety
Lavender may also provide support for people with anxiety.

In a large meta-analysis from 2019Trusted Source, people with anxiety disorders who took 160-milligram lavender oil capsules experienced significant decreases in anxiety.

Other studies have found similar results.

One from 2015Trusted Source involved 60 people in a coronary intensive care unit. The researchers found that those treated with lavender essential oil had lower levels of anxiety and better sleep.

Another study from 2010Trusted Source compared lavender capsules to the anti-anxiety medication lorazepam, concluding that lavender’s effects were comparable to the prescription drug.

Lessons Learned

Hair loss
Topical use of lavender oil might help to treat a disease called alopecia aerata, which causes a person’s hair to fall out in patches.

According to an older 1998 studyTrusted Source of 86 people with alopecia areata, 44 percent experienced improved hair growth after massaging an essential oil blend of thyme, rosemary, lavender, and cedarwood in a mixture of carrier oils into their scalp daily for seven months.

While this study is promising, it’s difficult to say whether the hair growth could be contributed to lavender specifically.

An animal study from 2021 also found that lavender oil successfully stimulated hair growth within a 28-day timeframe.

Headaches and migraine
The calming effects of lavender might be enough to soothe away a headache or migraine.

In one study from 2016, people with migraine who received 3 months of lavender therapy scored lower on a headache assessment scale than a control group.

In another 2012 studyTrusted Source, 47 participants with migraine inhaled lavender essential oil for 15 minutes. They experienced reduced headache severity and frequency.

Chemotherapy side effects
According to the National Cancer InstituteTrusted Source, aromatherapy can help people with cancer manage the side effects of their treatment. Lavender aromatherapy may help lower anxiety about cancer treatment procedures.

Conclusion

Depression
Lavender’s effects on depression aren’t as well documented as those on anxiety, but research is promising.

A small 2016 studyTrusted Source on postpartum women found that lavender aromatherapy prevented stress, anxiety, and depression after childbirth.

Another small 2015 study looked at people with kidney disease. The researchers found that those who inhaled a lavender scent for 1 hour during hemodialysis had lower scores of depression and stress than those who did not.

Older adults who drank lavender tea twice a day for 2 weeks in a small 2020 study experienced lower levels of anxiety and depression.

Acne
Compared to more aggressive treatments, lavender oil could be a gentle way to treat acne due to its ability to kill bacteria.

In a 2013 study, a combination of lavender oil and aloe extract effectively inhibited the growth of one bacterial strain that causes acne.

Burns
Lavender has long been used as a traditional remedy for burns, and some older researchTrusted Source has suggested there’s scientific data to confirm this use. According to a 2009 studyTrusted Source, its antimicrobial activity might also help prevent infections after a burn.

Skin conditions
Lavender contains two inflammation-fighting compounds called linalool and linalyl acetate. A 2020 study suggests that these may provide relief for skin issues, such as:

eczema
dermatitis
psoriasis
itching
rashes
Wound healing
Lavender’s soothing powers might extend to healing wounded skin.

A review of 20 studies found that lavender oil increased the rate of wound healing, promoted the growth of collagen, and boosted the tissue remodeling process of the skin.
