What is Lavender?
Lavender plants are aromatic evergreen small shrubs native to the Mediterranean region, the Arabian peninsula, Russia, and Africa. The plant has small blue or purple flowers. Fresh flowering tops are collected, and the essential oil is distilled or extracts are obtained by extracting with solvents. Lavender is cultivated extensively for use as a perfume, in potpourri, and as an ornamental.

Lavender has been used for pain, bacterial and fungal infections, depression, cramps, indigestion, to promote wound healing, and as a sedative. Extracts have been used to treat conditions ranging from acne to migraines.

Lavender has been used extensively for diabetes in parts of Spain and is included in some commercial herbal antidiabetic preparations. Fresh leaves and flowers are applied to the forehead to relieve headaches and to joints to treat rheumatic pain. The vapors of steamed flowers are used as a cold remedy. Chileans drink the tea to induce or increase menstrual flow.General uses
