Science and the Benefits of Lavender Essential Oil

Sedative herbal and natural supplements have been used since the middle ages to improve quality of life. (1) Essential oils of lavender have been used in alternative medicine for several centuries with the compounds that comprise these oils, especially linalool and linalyl acetate, having therapeutic qualities possessing calming and sedative effects making them popular in aroma-therapeutic practices. Science has reported several of the one-hundred plus compounds of lavender essential oil possess anticancer and anti-mutagenic properties.(2) There is mounting international evidence supporting the use of plant-derived essential oils against pathogenic microorganisms. (3)

“…promoting a product with claims that it treats or prevents disease or otherwise affects the structure or any function of the body may cause the product to be considered a drug.”(4) That does not mean, however, lavender doesn’t have a place in alternative medicine, just that Lavender has not gone through the registration process to be labeled as such. Here are a few of the hundreds of research papers focusing on the benefits of Lavender:

Antiseptic Qualities

  • Essential oils represent a cheap and effective antiseptic topical treatment option even for antibiotic-resistant strains such as MRSA (methicillin-resistant Staphylococcus aureus) and antimycotic-resistant Candida species. (5) (Candida is a fungus thus the term antibiotic would not be correct. Antibiotic relates to bacteria.)

  • The use of lavender essential oils and aroma therapeutic practices reduced anxiety in intensive care unit patients.(6)
  • Dental patients exposed to lavender essential oil had significantly reduced anxiety (7) and improved mood in a dental office. (8)
  • The reduction of anxiety (anxiolytic effects) has been linked to the activity of linalool. (9)


  • The antimutagenic properties of lavender make it a promising candidate for new applications in human health care, potential as a topical application to protect skin from cancer. (10)
  • Compounds found in trace amounts in lavender oils have potentially significant anticancer activity. (11)


  • Inhalation of the scent of lavender has been shown to decrease agitation in dementia patients. (12)
  • In combination with massage therapy, exposure to lavender aromatics has been shown to significantly decrease excessive motor behavior in subjects diagnosed with dementia. (13)
  • Lavender essential oil applied in skin cream supports the hypothesis that absorption of lavender essential oils through the nose and skin may assist in promoting mental health and reduce cognitive impairment of dementia patients. (14)


  • Lavender essential oil absorption into the bloodstream, either by inhalation or contact with the skin, has pharmacological effects in treating pain, anxiety, sleep disorders, and depression. (15)

Elderly Patients

  • Lavender aromatherapy has been found to reduce falls in elder nursery home residents (16) and improving stability. (17)
