The fragrant oil to which the odour of Lavender flowers is due is a valuable article of commerce, much used in perfumery, and to a lesser extent in medicine. The fine aromatic smell is found in all parts of the shrub, but the essential oil is only produced from the flowers and flower-stalks. Besides being grown for the production of this oil, Lavender is widely sold in fresh state as "bunched Lavender", and as "dried Lavender", the flowers are used powdered, for sachet making and also for pot-pourri, etc., so that the plant is a considerable source of profit. [...]The essential oil, or a spirit of lavender made from it, proves admirably restorative and tonic against faintness, palpitations of a nervous sort, weak giddiness, spasms and colic. It is agreeable to the taste and smell, provokes appetite, raises the spirits and dispels flatulence. The dose is from 1 to 4 drops on sugar or in a spoonful or two of milk. A few drops of the essence of Lavender in a hot footbath has a marked influence in relieving fatigue.
