Apart from having a delightful fragrance, lavender flowers are an effective and valued medicinal herb. The flowers are the most commonly used, but in some parts of the world the leaves are also used in making tinctures, decoctions, e·tc. Perhaps its most effective use is in a tincture where the oil is distilled from the herb. Lavender flowers are used as antispasmodics, sedatives, mild diuretic. They have been used in headaches, fainting, nervous prostration, and dizziness. The leaves have stomachic, carminative and chologogue properties. These are usually used as a tea for flatulence, nausea and vomiting.  Donsbach (1)

Lavender is widely used externally for its mild pain-relieving and anti‑inflammatory effects and is a favorite first aid remedy not only for burns but also minor wounds, sprains, insect bites and stings, athlete’s foot, and muscular aches and pains. Inhaled through the nose, lavender’s fresh, flowery  aroma has a sedating eflect on the central nervous system. It is a mild soporific that can help induce sleep, alleviate stress, and reduce depression and nervous tension. It may also boost immunity and alleviate headaches.

Buying lavender: It is sold as a concentrated liquid, typically in quantities of one ounce or less, as well as in a variety of body care products and combination remedies w·th names like Tranquillity and Euphoria.  NHS (1)
