In our fast-paced world, especially in urban areas, the need for natural solutions to manage stress and promote sleep quality has increased. Lavender, known for its calming scent and healing properties, has established itself as one of the most popular herbs for precisely these purposes. Whether in aromatherapy, in teas, or as a dietary supplement, lavender has a wide range of uses. In this article, we take a detailed look at its origins, benefits, mode of action, dosage, and more.

What is lavender?

Lavender (Lavandula angustifolia), also known as true lavender, belongs to the mint family (Lamiaceae). The plant is prized worldwide not only for its pleasant fragrance, but also for its healing and calming properties. Lavender has a long history of use in traditional medicine and has been used for centuries to relieve stress, anxiety, and sleep disorders.

Where does lavender come from?

Lavender originates from the Mediterranean regions and is found primarily in rocky, sunny landscapes. Provence in France is known worldwide as a lavender-growing region. However, lavender is also successfully cultivated in countries such as Spain, Italy, and even England. The dry, warm climate of these regions provides the perfect conditions for the plant's growth [1].

How is lavender made?

The production of lavender products begins with the harvesting of the flowers. These flowers are then dried or used directly to extract essential oil. The most popular method for extracting the oil is steam distillation, which extracts the essential compounds from the flowers. Alternatively, the flowers can be made into teas or used as a flavoring in cosmetics and personal care products. Lavender oil is valued not only for its fragrance but also for its calming properties, which are helpful for stress and sleep problems [2].

Health benefits of lavender

Lavender and stress

Lavender has been proven in numerous studies to be an effective remedy for stress and anxiety. The scent of lavender has a calming effect on the nervous system by reducing the production of stress hormones such as cortisol [3]. Some studies show that lavender oil can activate the parasympathetic nervous system, which lowers heart rate and blood pressure—both important indicators of relaxation [4]. Taking a lavender bath or applying lavender oil can therefore be a simple and natural way to unwind after a stressful day.

Lavender and sleep

One of the most well-known uses of lavender is its ability to promote sleep. Many people who suffer from insomnia or sleep disorders turn to lavender oil to help them get a better night's rest. Research has shown that inhaling lavender oil can improve sleep quality and reduce the time it takes to fall asleep [5]. Lavender is believed to have a calming effect by increasing GABA in the brain and reducing nervous system activity, thereby facilitating deeper and restful sleep. Regular use in the form of lavender pillows or teas has also shown positive effects.

Lavender and fear

Lavender is increasingly being used to treat anxiety because it offers a gentle and natural alternative to pharmaceutical sedatives. Studies have shown that lavender extract, when taken orally, can effectively reduce the symptoms of mild to moderate anxiety [6]. Compared to synthetic sedatives, lavender offers the advantage of being non-addictive and causing fewer side effects. Regular use of lavender, whether in the form of aromatherapy or capsules, can therefore be a useful addition in the treatment of anxiety disorders.

Lavender and skin health

Lavender is not only used internally but also externally to treat skin problems. Thanks to its anti-inflammatory and antimicrobial properties, lavender oil helps heal minor wounds, burns, and insect bites [7]. Lavender oil can also provide relief from skin conditions such as eczema or acne. It has a soothing effect on the skin and supports its regeneration, making it a popular ingredient in cosmetic products.

How does lavender work in the body?

Lavender's effects are based on the interaction of its essential oils with the nervous system. Lavender contains compounds such as linalool and linalyl acetate, which act on GABA receptors in the brain. These neurotransmitters are crucial for regulating nervous system excitability and promoting relaxation and calm [8]. Furthermore, the essential oils have antioxidant and anti-inflammatory properties, making lavender a valuable agent for general well-being.

Recommended dosage and use of lavender

What is the recommended dosage?

The recommended dosage of lavender varies depending on the application. For oral use of lavender oil capsules, a dose of 80 to 160 mg per day is recommended to relieve anxiety and sleep disturbances [9]. When used for aromatherapy, 2-3 drops in a diffuser are sufficient to calm the air. When used externally, such as to treat skin irritations, the oil should be diluted with a carrier oil such as almond oil to avoid skin irritation.

When should you take lavender?

To benefit from its sleep-promoting effects, it is recommended to use lavender approximately 30 minutes before bedtime, either by inhaling the oil or taking a capsule [10]. For stress or anxiety, lavender can be used several times throughout the day, depending on individual needs.

Side effects and safety of lavender

Is lavender safe?

Lavender is considered safe when used in recommended amounts. However, it is recommended not to take large amounts of lavender oil orally, as it may cause stomach upset or nausea [11]. Pregnant and breastfeeding women should seek medical advice before using lavender, especially if taken internally.

What are the side effects of lavender?

Potential side effects of lavender include skin irritation when used externally and gastrointestinal problems when ingested in excess [12]. People allergic to plants in the mint family should use lavender with caution. Furthermore, lavender oil should never be applied directly to open wounds or sensitive skin.

Lavender compared to other ingredients

Lavender vs. Lemon Balm

Both lavender and lemon balm (melissa) are commonly used for their calming properties, but they have different uses. While lavender is primarily used to calm and promote sleep, lemon balm is often used for digestive disorders or to promote cognitive function. Both plants have calming effects, but lavender is particularly effective in treating anxiety and insomnia [13].

Lavender vs. Chamomile

Lavender and chamomile are often used in aromatherapy, but they have slightly different properties. Chamomile is particularly known for its anti-inflammatory and skin-soothing properties, while lavender has a stronger effect on relaxing the nervous system. Both herbs can work synergistically when used together.

Sources of Lavender

Lavender grows primarily in Mediterranean regions, where the dry, sunny climate provides ideal conditions for its growth. There are no naturally occurring foods that contain lavender, but lavender flowers are often used to flavor foods and beverages, especially in teas, pastries, and desserts. The dried flowers can also be used in homemade herbal blends or as decoration [14].

Final Thoughts on Lavender

Lavender is a time-honored herbal remedy that can be used in a variety of ways to promote relaxation, better sleep, and overall well-being. Thanks to its calming effect on the nervous system and its anti-inflammatory properties, lavender is a versatile and safe remedy that no medicine cabinet should be without. Whether as an essential oil, tea, or dietary supplement, lavender offers a gentle, natural alternative to synthetic remedies, helping you reduce stress and sleep more peacefully.
