For other uses, see Lavender (disambiguation). The lavenders (Lavandula) are a genus of 39 species of flowering plants in the mint family, Lamiaceae, native to the Mediterranean region south to tropical Africa and to the southeast regions of India. The genus includes annuals, herbaceous plants, subshrubs, and small shrubs. The native range extends across the Canary Islands, North and East Africa, Southern Europe and the Mediterranean, Arabia and India. Because the cultivated forms are planted in gardens world-wide, they are occasionally found growing wild as garden escapees, well beyond their natural range. However, since lavender cross-pollinates easily, there are countless variations within the species. The color of its flowers has come to be called lavender.
[edit] Nomenclature and taxonomy
[edit] UsesThe most common "true" species in cultivation is the common lavender Lavandula angustifolia (formerly L. officinalis). A wide range of cultivars can be found. Other commonly grown ornamental species are L. stoechas, L. dentata, and L. multifida. Lavandula x intermedia or "Lavendin" is the most cultivated species for commercial use, since its flowers are bigger and the plants are easier to harvest, but Lavendin oil is regarded to be of a lower quality.[1] Lavenders are widely grown in gardens. Flower spikes are used for dried flower arrangements. The fragrant, pale purple flowers and flower buds are used in potpourris. Dried and sealed in pouches, they are placed among stored items of clothing to give a fresh fragrance and as a deterrent to moths. The plant is also grown commercially for extraction of lavender oil from the flowers. This oil is used as an antiseptic and for aromatherapy. Lavender is also used extensively as herbal filler inside sachets used to freshen linens and discourage moths from closets and drawers. Dried lavender flowers have become recently popular used as confetti for tossing after a wedding. Lavender is often used as a 'relaxation' drug, called Lavendine (purple sniff) which is made from ground up lavender flowers. It is one of the few legal drugs however is not used much anymore, lavendine was most popular between 1972 and 1983 after which it became less and less used. [edit] Culinary useLavender flowers yield abundant nectar which yields a high-quality honey for beekeepers. Lavender monofloral honey is produced primarily in the nations around the Mediterranean, and marketed worldwide as a premium product. Lavender flowers can be candied and are sometimes used as cake decorations. Lavender is also used to flavour baked goods and desserts (it pairs especially well with chocolate), as well as used to make "lavender sugar"[2]. Lavender flowers are occasionally sold in a blend with black, green, or herbal tea, adding a fresh, relaxing scent and flavour. Chefs in and around Provence, France, have been incorporating this herb into their cuisine for centuries, either alone or as an ingredient of herbes de Provence. Lavender lends a floral, slightly sweet, and elegant flavour to most dishes, and pairs beautifully with various sheep's and goat's cheeses. For most cooking applications it is the dried buds (also referred to as flowers) of lavender that are used, though some chefs experiment with the leaves as well. Only the buds contain the essential oil of lavender, which is where both the scent and flavour of lavender are best derived. The French are also known for their lavender syrup, most commonly made from an extract of lavender. In the United States, both French lavender syrup and dried lavender buds are used to make lavender scones and marshmallows. [edit] Medicinal use
Lavender has been used extensively in herbalism. English lavender (Lavandula angustifolia) yields an essential oil with sweet overtones, and can be used in balms, salves, perfumes, cosmetics, and topical applications. Lavandin, Lavandula x intermedia (also known as French lavender), yields a similar essential oil, but with higher levels of terpenes including camphor, which add a sharper overtone to the fragrance. Mexican lavender, Lavandula stoechas is not used medicinally, but mainly for landscaping. Essential oil of lavender has antiseptic and anti-inflammatory properties. It was used in hospitals during WWI to disinfect floors and walls. These extracts are also popularly used as fragrances for bath products. An infusion of lavender is claimed to soothe and heal insect bites. Bunches of lavender are also said to repel insects. If applied to the temples, lavender oil is said to soothe headaches. Lavender is frequently used as an aid to sleep and relaxation: Seeds and flowers of the plant are added to pillows, and an infusion of three flowerheads added to a cup of boiling water are recommended as a soothing and relaxing bedtime drink. Lavender oil (or extract of Lavender) is claimed to heal acne when used diluted 1:10 with water, rosewater, or witch hazel; it is also used in the treatment of skin burns and inflammatory conditions (it is a traditional treatment for these in Iran and nearby regions). [edit] Health precautionsThere is scientific evidence to support the effectiveness of some of these remedies, especially the anti-inflammatory effects, but they should be used with caution since lavender oil can also be a powerful allergen. Ingesting lavender should be avoided during pregnancy and breastfeeding.[3]. Topically, lavender oil is cytotoxic. It increases photosensitivity as well. A study demonstrated lavender oil is cytotoxic to human skin cells in vitro (endothelial cells and fibroblasts) at a concentration of 0.25%. Linalool, a component of lavender oil, reflected the activity of the whole oil, indicating that linalool may be the active component of lavender oil.[4] Another study showed aqueous extracts reduced mitotic index, but induced chromosome aberrations and mitotic aberrations in comparison with control, significantly. Aqueous extracts induced breaks, stickiness, pole deviations and micronuclei. Furthermore, these effects were related to extract concentrations.[5] Two essential oils, lavender and tea tree oil, have been implicated in causing gynaecomastia, an abnormal breast tissue growth in prepubescent boys. An article in the New England Journal of Medicine claimed the use of shampoo and similar products, containing lavender and tea tree oils, in three boys resulted in this condition.[6] Professor Ieuan Hughes, a child hormone specialist at the University of Cambridge has claimed "... these oils can mimic oestrogens" and "people should be a little bit careful about using these products". [7][8]. [edit] History
The ancient Greeks called the lavender herb nardus, after the Syrian city of Naarda. It was also commonly called nard.[9] Lavender was one of the holy herbs used in the biblical Temple to prepare the holy essence, and nard is mentioned in the Song of Solomon (4,14)
During Roman times, flowers were sold for 100 denarii per pound, which was about the same as a month's wages for a farm labourer, or fifty haircuts from the local barber. Lavender was commonly used in Roman baths to scent the water, and it was thought to restore the skin.[citation needed] Its late Latin name was lavandārius, from lavanda (things to be washed), from the verb lavāre (to wash).[12] When the Roman Empire conquered southern Britain, the Romans introduced lavender.[citation needed] The Greeks discovered early on that lavender if crushed and treated correctly would release a relaxing fume when burned, this is the basis for the lavendine (purlple sniff) drug used for medical purposes today.
