Native to France and the western Mediterranean, it is now cultivated worldwide for its volatile oil. It is grown as a garden plant as far north as Norway. Lavender is a perennial shrub, growing to about three feet, producing spikes of violet-blue flowers that extend above the foliage. Some varieties have flowers of pale pink, dark purple, white, or magenta and are harvested toward the end of flowering season when the petals have begun to fade. They are generally picked by the end of July to obtain maximum strength in its essential oils, with sixty pounds of flowers yielding about sixteen fluid ounces of oil.


One of the most popular medicinal herbs since ancient times, its name is derived from the Latin lavare, meaning to wash. The Greeks and Romans were fond of it in their bath water.

Since ancient times, the oil has been used to kill lice and fleas and as an embalming fluid.

It became popular as a medicine during the late Middle Ages and taken to the New World by Pilgrims in 1620.

As a strewing herb, lavender was popularly used to mask the smells of households and streets.

Traditional Uses

Lavender is well-known for its soothing and calming effect; and, when combined with other sedative herbs, relieves insomnia, irritability, headaches, migraines, and depression. Medicinally, lavender has many uses, especially in aromatherapy, and is used by midwives, massage therapists, and some hospitals.

Its significant amounts of volatile oil soothes indigestion and colic, relieving gas and bloating.

It is also used to treat asthma and, through its relaxing effects, is especially effective when excessive nervousness is the trigger.

The essential oil is strongly antiseptic and a valuable first aid remedy helpful in treating minor burns, wounds, and sores. It is also effective on insect stings as it relieves the pain and inflammation.

The dried flowers are often hung in rooms to perfume the air and repel moths and other insects.

When placed near or inside a pillow, dried lavender helps promote a restful sleep. A few drops in the bathwater can relieve tension and mild depression, while promoting sleep.

The English and French varieties are especially prized for their essential oils, which are used in perfumes, cosmetics, skin care products, and air fresheners.
