.... Parts Used:
Essential oil is extracted from the fresh flowers of the lavender plant and used for medicinal purposes.
Medicinal Uses and Indications:
Human clinical studies have reported that lavender essential oil may be beneficial in a variety of conditions, including insomnia, alopecia (hair loss), anxiety, stress, postoperative pain, and as an antibacterial and antiviral agent. Lavender oil is also used together with other forms of integrative medicine, such as massage, acupuncture, and chiropractic manipulation.
Insomnia
In folklore, pillows were filled with lavender flowers to help the restless fall sleep. There is now scientific evidence to suggest that aromatherapy with lavender may slow the activity of the nervous system, improves sleep quality, promote relaxation, and lift mood in people suffering from sleep disorders. Studies also suggest that massage with essential oils, particularly lavender, may result in improved sleep quality, more stable mood, increased mental capacity, and reduced anxiety. In one recent study, participants who received massage with lavender felt less anxious and more positive than participants who received massage alone. Lavender flowers have also been approved in Germany as a tea for insomnia, restlessness, and nervous stomach irritations.
Alopecia areata
In one study of 86 people with alopecia areata (a disease of unknown cause characterized by significant hair loss, generally in patches), those who massaged their scalps with lavender and other essential oils daily for 7 months experienced significant hair re-growth compared to those who massaged their scalps without the essential oils. It is not entirely clear from this study whether lavender (or a combination of lavender and other essential oils) was responsible for the beneficial effects.
Other uses
Aromatherapists also use lavender as a tonic in inhalation therapy to treat headaches, nervous disorders, and exhaustion. Herbalists treat skin ailments, such as fungal infections (like candidiasis), wounds, eczema, and acne, with lavender oil. It is also used externally in a healing bath for circulatory disorders and as a rub for rheumatic ailments (conditions affecting the muscles and joints). One study evaluating essential oils, including lavender, for treating children with eczema concluded that the oils added no benefit to therapeutic touch from the mother; in other words massage with and without essential oils was equally effective in improving the dry, scaly skin lesion. A recent study found that the use of lavender oil may improve postoperative pain control. Fifty patients undergoing breast biopsy surgery received either oxygen supplemented with lavender oil or oxygen alone. Patients in the lavender group reported a higher satisfaction rate with pain control than patients in the control group.
Available Forms:

• Aromatherapy oil
• Bath gels
• Extracts
• Infusions

How to Take It:
Pediatric
• Oral use in children is not recommended.
• May be used topically in diluted concentrations to treat skin infections and injuries, such as minor cuts and scrapes. DO NOT USE ON OPEN WOUNDS -- seek medical attention. A small study published in the New England Journal of Medicine in 2007, however, concluded that lavender and tea oils in some shampoos, soaps, and lotions may cause gynecomastia, breast development in a male, in boys.
• May be used as aromatherapy for children. Use 2 - 4 drops in 2 - 3 cups of boiling water. Inhale vapors for headache, depression, or insomnia.
Adult
The following are recommended adult doses for lavender:
• Internal use: Tea: 1 - 2 tsp whole herb per cup of hot water. Steep for 10 - 15 minutes and drink, 1-3 times a day.
• Tincture (1:4): 20 - 40 drops, 3 times a day
• Inhalation: 2 - 4 drops in 2 - 3 cups of boiling water. Inhale vapors for headache, depression, or insomnia.
• Topical external application: lavender oil is one of the few oils that can be safely applied undiluted. For ease of application, add 1 - 4 drops per tablespoon of base oil (such as almond or olive oil). DO NOT USE LAVENDER OIL INTERNALLY. Also, avoid contact with the eyes or mucous membranes such as the lips and nostril.
Precautions:
The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, contain active components that can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a health care provider qualified in the field of botanical medicine.
Although side effects are rare, some individuals may develop an allergic reaction to lavender. Nausea, vomiting, headache, and chills have also been reported in some individuals following inhalation or absorption of lavender through the skin.
Pregnant and breast-feeding women should avoid using lavender.
Possible Interactions:
• CNS Depressants -- There are no known scientific reports of interactions between lavender and conventional medications. However, due to the relaxing qualities of lavender, this herb could potentially enhance the effects of central nervous system depressants, including narcotics (such as morphine or oxycodone) for pain and sedative and anti-anxiety agents (such as lorazepam, diazepam, and alprazolam). Talk to your health care provider before using lavender with these and other sedating medications.
