Why it’s Wonderful

Lavender has a fascinating history from ancient times.  Legend has it that Adam and Eve took lavender with them as they fled the Garden of Eden.  The Egyptians, Phoenicians and Arabians used lavender for cleansing, for preparing mummies, and sent urns of the flowers with their kings into their graves.  Cleopatra famously used lavender for seduction.  It is believed that lavender was used to honor Jesus Christ as a baby, to anoint his feet with the essential oils (when Mary used “spikenard”), and to wrap his body when he was buried.  Lavender shares the same root word as “lavar” in Latin, meaning to wash (or some argue, “livendulo”, meaning the color blue). The ancient Romans had famed aromatherapy baths with lavender. This is surely due to the natural antiseptic and cleansing properties of lavender. The Romans even lavender1made wine with lavender, and lavender has been used in naturopathy and gourmet cooking for thousands of years.  Josephine was said to make a special hot chocolate drink for Napoleon, for which the secret ingredient was lavender (and was believed to fuel their great passion).  During the Bubonic Plague, lavender was a key ingredient in the so-called “Thieves Oil” that enabled nefarious robbers to pilfer the bodies and homes of the stricken.  Both Elizabeth I and Queen Victoria were enamored of lavender, and insisted it fill their palaces in its many forms.  Lavender was brought to the Americas in the 1600s with the Pilgrims, and was used for wounds in battle as recently as World War I.

The medicinal and soothing properties of lavender go far beyond helping us get clean. In our current time, many studies have been done on the medicinal and therapeutic benefits of lavender oil (more than 1,500 studies as of August 2014), and these studies yielded some pretty incredible findings. I’ve listed some of these findings below, all taken from study abstracts listed on PubMed, or the U.S. National Library of Medicine hosted by the National Institute of Health.

[Note: Please bear in mind these studies were performed on Lavandula: Angustifolia essential oil, and the majority of lavender products available are made with other lavenders (such as Lavandula: x intermedias) because they are less expensive to produce and the plants yield higher quantities of oil. These other lavenders do have some medicinal/therapeutic properties, but at lower levels and often the quality is not high. Please see my discussion of lavender Varieties for more information.]

Reduction of stress/mood elevator
• Significantly reduced blood pressure, heart rate and skin temperature (i.e. reduces physiological stress). (1)
• Calmed nerve activity and caused more relaxed state. (2)
• Showed pronounced antidepressant effect and improved general mental health. (3)
• Literature review confirmed clinical trials on lavender suggest antidepressive influence. (4)
• Calming olfactory effect induced a broader attentional state. (5)
Reduction of Anxiety and Insomnia
• Significantly reduced symptoms of anxiety disorders, including disturbed sleep, somatic complaints comparable to Lorazapam. (6)
• Reduced the anxiety related symptoms and sleep disturbances in major depressive disorder (MDD) patients, with an anxiolytic effect comparable to Lorazapam. (7)
Reduction in pain and wound healing
• Reduced pain in many different studies: post-tonsillectomy pain in pediatric patients (8) , Cesarean postoperative pain (9) , resulting in significantly lower usage of pain  medications such as acetaminophen.
• Improved parasympathetic nervous system activity, and alleviated PMS (premenstrual syndrome). (10)
• Aided in wound healing. (11)
• Suppressed allergic airway inflammation for bronchial asthma. (12)
• Showed protective effect against reproductive damage and oxidative stress in diabetic rats. (13)
Antimicrobial properties
• Improved the antimicrobial activity of other essential oils when used in a blend. (14)
• Reversed E. coli’s multi-drug resistance by reversing its bacterial resistance, opening the door for new options for phytopharmaceuticals. (15) (16)
• Shown to grow cultivable endophytic bacteria on the plant itself that has bioactive compounds relevant in the field of pathogen control and human health (i.e. it seems to be able to kill pathogens that would otherwise harm us). (17)
Effects on the brain
• Showed neuroprotective activity against cerebral ischemia in studies on strokes, as well as inhibiting oxidative stress. (18)
• Increased antioxidant enzyme activities, reduced rates of cellular death, and potent neuroprotective effects on rats’ brains. (19)
• Worked to reduce neuropathic pain and anxiety in the hippocampus in the same range as the drug pregabalin. (20)
• Increased theta and alpha brain activity, and showed obviously more scattering power in alpha range waves particularly in bilateral temporal and central areas of the brain. (21)
Other impacts of lavender
• Aided in the healing of burns. (22)
• Effective mosquito repellent. (23) (24)
• Reduced insect infestation of apple orchards by 95%. (25)
• Reduced insect infestation in camel herds by 100%. (26)
• Honey made including lavender compounds include benefits of the lavender. (27)
Lavandula: Dentata (a section of Lavender carved out from Stoechas) shown to be cytotoxic on human breast adenocarcionoma cells (anticancer). (28)
