LAVENDER Overview Information
Lavender is an herb. The flower and the oil of lavender are used to make medicine.
Lavender is used for restlessness, insomnia, nervousness, and depression. It is also used for a variety of digestive complaints including meteorism (abdominal swelling from gas in the intestinal or peritoneal cavity), loss of appetite, vomiting, nausea, intestinal gas (flatulence), and upset stomach.
Some people use lavender for painful conditions including migraineheadaches, toothaches, sprains, nerve pain, sores, and joint pain. It is also used for acne and cancer, and to promote menstruation.
Lavender is applied to the skin for hair loss (alopecia areata) and pain, and to repel mosquitoes and other insects.
Some people add lavender to bathwater to treat circulation disorders and improve mental well being.
By inhalation, lavender is used as aromatherapy for insomnia, pain, and agitation related to dementia.
In foods and beverages, lavender is used as a flavor component.
In manufacturing, lavender is used in pharmaceutical products and as a fragrance ingredient in soaps, cosmetics, perfumes, potpourri, and decorations.
Lavender (scientific name Lavandula angustifolia) is commonly contaminated with related species, including Lavandula hybrida, which is a cross between Lavandula angustifolia and Lavandula latifolia, from which lavandin oil is obtained.
How does it work?
Lavender contains an oil that seems to have sedating effects and might relax certain muscles.
LAVENDER Uses & Effectiveness 
Possibly Effective for:
- Hair loss in a condition called alopecia areata when applied to the scalp in combination with oils from thyme, rosemary, and cedarwood. There is some evidence that this combination might improve hair growth by as much as 44% after 7 months of treatment.
Insufficient Evidence for:
- Depression. In mild to moderate depression, tincture of lavender appears to be slightly less effective than the medicationimipramine (Tofranil).
- Sleeplessness (insomnia). Developing research suggests using lavender oil in a vaporizer overnight or on a gauze pad left beside the bed, might help some people with mild insomnia.
- Agitation in dementia. Study results have not agreed. In one study, nightly use of lavender oil in a bedside diffuser for 3 weeks reduced agitation in patients with various types of dementia. However, in another study, continuous use of lavender oil on a pad attached to a patient's shirt had no effect in a small group of patients with advanced dementia.
- General psychological well being. Some research suggests that adding 3 mL of a 20% lavender oil and 80% grapeseed oil mixture to daily baths produces small improvements in mood, compared with baths containing grapeseed oil alone.
- Migraine. Some research suggests that rubbing 2 or 3 drops of lavender oil on the upper lip, so that the vapor is inhaled, might reduce migraine pain and nausea, and help stop the headache spreading.

The safety of these products when used by young girls is not known.Pregnancy and breast-feeding: Not enough is known about the use of lavender during pregnancy and breast-feeding. Stay on the safe side and avoid use.
