Its medicinal properties have been revered since ancient times, and the herb has been even used as a food seasoning. Classically beloved, lavender boasts a long history of applications.
Lavender Medicinal Properties
Health Benefits of Lavender
The majority of lavender benefits derives from the volatile oils found in the petals of its flowers, which, when distilled into lavender essential oil, are considered an important first aid remedy thanks to their antiseptic, analgesic, and sedative effects.
Traditionally, lavender benefits have found the a variety of medicinal uses, mainly:
Inducing sleep. Lavender properties include mild sedative effects, which help relieve stress, inducing relaxation and sleep.

Soothing headaches. Due to its sedative properties, lavender can help alleviate tension headaches when inhaled or rubbed into the skin.
Relieving digestive symptoms. The medicinal properties of lavender include analgesic and anti-inflammatory actions, which can be useful for soothing minor digestive complains.
How It Works
The major constituents of lavender essential oil are cineole, camphor, borneol, linalool and linalyl acetate, all of which work together in order to provide lavender benefits.
Cineol have been shown to have analgesic and muscle relaxant activities, which inhibit periferal neurons' stimuli, whereas camphor is responsible for the antiseptic, antimicrobial effects of lavender. On the other hand borneol's interaction with gamma-aminobutyric acid (GABA), a neurotransmitter that regulates fear and anxiety responses, along with the influence of linalool and linalyl acetate over the nervous system, explains the analgesic, sedative, and anti-inflammatory actions of lavender essential oil when topically applied or inhaled.
Furthermore, an increasing number of studies are suggesting that lavender essential oil may be useful in treatment of several neurological disorders.

The lavender plant (Lavandula angustifolia, formely known as Lavandula officinalis) is a hardy, small bush that likes temperate climates and is very easy to take care of. Its pretty flowers have also a soothing, aromatic scent, which is why they are often used in herbal essences and potpourris.
Lavender seeds are best sown in the spring well after the last frost of the season to allow for one to three months of germination at temperatures reaching 59°F (15°C).
The lavender plant prefers light, dry, poor to moderately fertile soil, with a slight alkalinity and full sun exposure, but it can also be grown indoors, in a spot with plenty of natural light.
If growing it outdoors, the lavender bush must be placed in a sunny spot, in cultivar hedges with a spacing of one to three feet (30 - 100 cm) between plants.
While the lavender bush is drought and wind tolerant, plants should generally be replaced every 10 years due to wear and tear.
Pruning the flower stalks in spring months will encourage lavender plant's growth.

A lavender bush can reach approximately three feet (1 m) tall and grow almost as wide. All lavender varieties are comprised of many spikes of opposite foliage that end in violet to blue flowers. Fresh or dried, the blooms are the most coveted part of the lavender plant, harvested for their high concentration of volatile oils and other nutrients.
Lavender (Lavandula angustifolia, formerly known as Lavandula officinalis) belongs to the Lamiaceae family, and it is thus linked to over 7,200 species of primarily aromatic herbs, including basil (Ocimum basilicum), rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris), and oregano (Origanum vulgare).
Varieties and Subspecies of Lavender
Due to its incredible popularity as an aromatic herb, there are several different cultivars of lavender, but there are only two true subspecies: Lavandula angustifolia angustifolia, coming from the northeastern part of the Iberian Peninsula near the Pyrenees, and Lavandula angustifolia pyrenaica, which is native to southeast France and some parts of Italy.
The cultivars of English lavender (Lavandula angustifolia), considered as the true lavender, are chosen mainly for their tolerance to frost, their fragrance, and the color of their flowers. Among the most popular are:
'Hidcore': compact shrub, with gray-silver leaves and dark purple flowers.
'Munstead': compact shrub, with green foliage and bluish flowers.
'Twickel Purple': with elongated spikes and fragrant flowers, dark purple.
'Mini Blue': compact and ideal for planters.
The name of lavender comes from the Latin lavare (to wash), which refers to its traditional uses: disinfecting wounds and aromatizing bathtubs.
Hailing from the rocky, temperate coasts of the western Mediterranean, lavender was domesticated over 2,500 years ago, where it spread first from Egypt northward to Greece and Rome. Lavender was also the preferred scent of kings for centuries, reaching England in the 1600s and becoming an integral part of British and colonial culture soon afterwards.
In Medieval times, lavender was commonly used to scent clothing to the extent where washerwomen became known as "lavenders."
Early Christians infused the flower with great religious meaning, and it remained a symbol of holy love for millennia.
In recent years, lavender production has become a multimillion-dollar industry, important for the flower itself but also for its valuable essential oil. France is currently the largest producer of lavender, due to its large plants; however, the lavender essential oil industry is led by Bulgaria, which produces about 220 tons per year, followed by France, England and Russia. True lavender is largely cultivated in Europe alone, though other similar species are found in North America, Asia, and Australia.
