Lavender has long been used as a fragrance. Although the plant's chief medicinal value formerly was as a sedative, modern-day herbalists prescribe lavender oil diluted form for intestinal gas, and scientific evidence indicates that this use is valid. There is not sufficient pharmacological proof, however, to support lavender's use as an antispasmodic. The dried flowers have been said to repel moths.
Lavender oil may be poisonous; no more than two drops should be taken internally in undiluted form.
