Lavandula (common name lavender) is a genus of 47 known species of flowering plants in the mint family, Lamiaceae.
Lavender is an aromatic perennial evergreen shrub. Its woody stems bear lavender or purple flowers from late spring to early autumn, although there are varieties with blossoms of white or pink. Lavender is native to the Mediterranean, but now cultivated in cool-winter, dry-summer areas in the Southwestern United States. The use of Lavender goes back thousands of years, with the first recorded uses by the Egyptians during the mummification process. Both the Greeks and the Romans had many uses for it, the most popular being for bathing, cooking, and as an ingredient in perfume. Lavender was used as an after-bath perfume by the Romans, who gave the herb its name from the Latin lavare, to wash. During the Great Plague of 1665, grave robbers would wash their hands in a concoction called Four Thieves Vinegar, which contained lavender, wormwood, rue, sage, mint, and rosemary, and vinegar; they rarely became infected. Benefits of lavender include its ability to relieve stress, improve mood, promote restful sleep, lower skin irritation, prevent infections, reduce inflammation and even eliminate dandruff.
