The Therapeutic Benefits of Lavender
Known for its light purple color and sweet floral scent, lavender has been used for centuries as a versatile medicinal herb. Today, interest in lavender continues to grow as research uncovers its wide range of potential health and wellness applications.
Understanding Lavender
Lavender refers to over 47 different species of flowering plants in the mint family, with English lavender (Lavandula angustifolia) being the most common variety grown for commercial use. Native to the Mediterranean region, lavender is now cultivated around the world.
The most prized part of the lavender plant are the fragrant purple flower spikes, which are steam distilled to produce lavender essential oil. Popular for its aromatic and therapeutic properties, lavender oil has many applications including perfumes, soaps, cleaning products, and aromatherapy.
Benefits of Lavender Oil
A number of small studies suggest lavender essential oil may provide various health benefits when used aromatheraputically, including:
- Reducing anxiety and emotional stress
- Improving sleep quality
- Easing pain from tension headaches and migraines
- Enhancing mood in people with depression
- Alleviating nausea and vomiting related to surgery or chemotherapy
Additional research indicates oral lavender supplements may help with anxiety and related conditions. However, more studies are needed to confirm lavender's therapeutic effects, especially with ingestion.
How Does Lavender Work?
Researchers believe lavender interacts with the limbic system, the region of the brain that regulates emotions. Inhalation of lavender scent may stimulate the production of calming neurotransmitters like gamma-aminobutyric acid (GABA).
The bioactive compounds in lavender oil, including linalool and linalyl acetate, also appear to have sedative, anti-inflammatory, and pain-relieving capabilities. This may explain lavender's ability to ease headaches, anxiety, and similar discomforts.
Growing Lavender
With its beautiful flowers and pleasant aroma, lavender makes an excellent addition to any herb or ornamental garden. Here is some key information on how to grow this multipurpose plant at home:
Choosing Varieties
English lavender (Lavandula angustifolia) and its cultivars are winter hardy to USDA zone 5 and do best in hot, sunny locations with well-drained soil. Spanish lavender (Lavandula stoechas) and French lavender (Lavandula dentata) are only hardy to zones 8-9 but good choices for hot climates.
Ideal Growing Conditions
Lavender thrives best in the following conditions:
- Sunlight: At least 6 hours of direct sun daily
- Soil: Slightly alkaline, sandy or gravelly soil with good drainage
- pH: 6.7-7.3
- Temperatures: Not lower than 5 F(-15 C)
- Water: Low moisture, allow soil to dry between waterings
Avoid wet or heavy clay soils which can cause root rot. Raised beds or mounds improve drainage.
Planting and Care
Lavender can be grown from seed, cuttings, or transplants. Plant in spring once all danger of frost has passed. Space plants 12-24 inches apart in rows 2-3 feet apart. Water weekly until established, then only occasionally during drought. Prune plants after the first bloom to promote bushy growth.
Lavender is relatively pest and disease resistant. Ensure good air circulation to prevent fungus or mildew. Apply mulch around the base to suppress weeds and retain moisture. Fertilize very sparingly to avoid excessive foliage at the expense of flower production.
Using Lavender
Beyond its ornamental appeal and therapeutic benefits, culinary grade lavender has a sweet, floral flavor that enhances many foods and beverages. The flowers and leaves can be used fresh or dried in baked goods, jellies, syrups, liqueurs, and sachets.
Popular Lavender Products
Due to lavender's calming properties, it's a common ingredient in relaxation and stress relief products like:
- Bath bombs, salts, and soaks
- Room diffusers and sprays
- Aromatherapy inhalers
- Pillows and sleep masks
- Candles
- Massage oils and lotions
When shopping for lavender products, look for those made with pure essential oil or culinary grade dried lavender. Avoid synthetic fragrance oils which don't provide therapeutic benefits.
DIY Lavender Projects
Consider crafting some homemade lavender goodies like:
- Lavender lemonade: Infuse simple syrup with dried lavender, then mix with lemon juice and water
- Lavender eye pillow: Fill a small fabric pouch with dried lavender buds and gently heat in the microwave for an aromatic, soothing eye compress
