LAVENDER Essential Oil

Lavendula Augustifolia is known as True Lavender

 Family: Labiatae/Lamiaceae -mint family, native to the Mediterranean, and evergreen perennial plant. Grows up to 40-60cm, flowers grow in spikes 3-4 per stem. Flowers are pale violet color but can also be white or pink.

Lavender is grown in Bulgaria, Kashmir India, France, Poland, Spain, Italy, Australia, China, Canada, Hungary, and many other places. Flowers, buds, and leaves are used for the oil. Stream distillation is used without harming active ingredients.

A leading supplier of essential oils Aromaaz International stated Lavender’s benefits:

• Promotes relaxation and relieves anxiety.
• Prevents fungal infection and heals eczema, burns, and scars.
• Useful in the treatment of depression, migraine, panic, headache, and insomnia and it calms our nerves.
• Helps fight conditions like asthma, bronchitis, throat infections, laryngitis, whooping cough, halitosis, nausea, vomiting, colds, and flatulence.
• Relieve pain in people suffering from arthritis, rheumatism, and any type of pain.
• Especially useful in revitalizing and toning up the skin. It helps in any type of skin problem including acne, insect bites, sunburn, boils, burns, oily skin, and others.

Each essential oil consists of over 200-300 active constituents (chemical makeup or properties) that are unique to just that plant, tree, or shrub. Various parts of that plant (stem, leaves, bark, resin, flowers) are used in making oil and can contain different active constituents designed by nature for protection and growth. The overall chemical makeup depends on genotype, location with soil and climate conditions, breeding, and structural features. The mixture of the chemistry of the plant gives us the aroma. Plants also contain minerals such as calcium, potassium, magnesium, zinc, copper, manganese, and iron.

The active chemical constituents of Lavender oil are linalool 37 – 40% and linalyl acetate 35-37%. Other active properties are a-terpineol, coumarin, and borneol.

Compounds could be higher depending on where the Lavender is grown. These active compounds are what give the following medicinal effects.

Anti-bacterial Effects

Poland Lavender showed high activity against gram-positive bacteria of B. subtilis and S. aureus and gram-negative bacteria of E. coli and P. aeruginosa and inhibits their growth when concentrates of .06 or 1.0 mL-1. Antimicrobial activity was seen with Poland lavender against yeast and molds (candida, A. niger, and P. expansum).

Anti-fungal Effects

A variety of Australian-grown lavender was examined against four fungi. Lavandulla Augustifolia is effective against fungi Trichophyton rubrum and Aspergillus fumigatus. Lavender oils can inhibit the growth of Aspergillus niger, Aspergillus ochraceus, and Fusarium culmorum from 29-93%. Other lavender species (L. x intermedia, L. stochas, & L. x allardii) from Australia have the properties to inhibit fungi as well. Cited from Moon et al., 2007, Journal of Essential Oil Research, vol 19, 171-175).

Anti-inflammatory Effects

Transcriptional analysis showed how Lavender was able to influence the macrophages of the immune system against Staphylococcus aureus infection. This bacterium is highly resistant to antibiotics. Treatment with Lavender increased the phagocytic rate and stimulated the suppression of the bacteria from replicating. Lavender also balanced the inflammation signaling prompted by the bacteria by repressing the pro-inflammatory cytokines and their receptors of the immune system while inducing the oxygenase-1 gene expression. This research inspires the potential development of lavender as an anti-inflammatory and immune regulatory coadjutant drug. Cited from Giovannini et al., 2016, Immunological Investigations, vol 45(1), 11-28. Doi: 10.3109/08820139.2015.1085392

Inflammation is a complex biological process and lavender was studied for its effects on the acute inflammatory response. This study showed compounds of 1.8 cincole, 39.83%, borneol 22.63%, and camphor 22.12%. Lavender plants were from Brazil, the leaves and stems were used, and the oil was extracted by steam distillation. Male Swiss mice were used in the experiment and supplied by Central Animal House at the University of Maranga, Brazil.  The amount of oil applied up to 10 mL did not produce cytotoxicity (destroys cells).  The amount of oil up to 1 mL used on the ear edema model reduced formation, myeloperoxidase activity, and nitric oxide. In the paw edema model, the oil amount was up to 250 mg and had the same effect as in the ear edema model. This experiment was able to produce evidence that Lavender presented anti-inflammatory action.  Cited from Cardia et al., 2018, Evidence-based Complementary and Alternative Medicine, ID1413940. Doi: 10.1155/2018/1413940

Antimicrobial Action boosts the Immune system

The study showed the antimicrobial action of lemon, tea tree, and lavender in washing liquid at 5% proves to inhibit Staphylococcus aureus (bacteria-MRSA), Candida sp. (yeast-fungi), and A. niger (fungi- black mold) with synthetic preservative added to ensure stability. Cited from Kunicka-Styczynska et al., 2011, International Journal of Cosmetic Science vol 33, 53-61. DOI: 10.1111/j.1468-2494.2010.00582.x

Lavender oil was tested with 45 other essential oils to investigate the interaction of therapeutic properties. The most favorable interaction was seen with lavender and Cinnamon (CZ) or with citrus Sinensis (sweet orange) against C. Albicans and Staphylococcus aureus. In a one-to-one ratio, 75.6% of the oils showed synergistic or additive results when blended with lavender.

Two hybrids of the lavender family (L. simian and L. Grosso) were tested on their antimicrobial actions on 16 multidrug-resistant strains of Pseudomonas aeruginosa. Pseudomonas aeruginosa is a Gram-negative, aerobic rod bacterium of the Pseudomonadaceae family. Commonly found in soil and water as well as in plants and humans. It can invade any tissue struggling with immunodeficiency. P. aeruginosa causes infection in the urinary tract, respiratory system, dermis, soft tissue, bone and joint, gastrointestinal, and blood, particularly in patients with severe burns, tuberculosis, cancer, and AIDS. Importantly, P. aeruginosa causes a significant problem in patients hospitalized with cancer, cystic fibrosis, and burns, with 50% fatality according to the Centers for Disease Control and Prevention (CDC). Both lavender oils had no cytotoxic effect at low concentrations. The oils were able to reduce nitric oxide synthase activity on murine macrophages.

Anti-viral Effects

In view of the Covid-19 pandemic, experiments were conducted on lavender and common sage to combat avian influenza H5N1. Lavender’s major constituents were linalyl and linalool. Sage’s components were white camphor and α-thujone. Both oils were effective at being a natural anti-inflammatory, antioxidant, and antiviral agent Cited from Baker et al., 2021, Journal of Agricultural and Food Research, vol 4,100135.

Aromatherapy Environment

Workplace stress cost the US more than $150 billion in stress-related problems. Stress is a significant factor that adds to job dissatisfaction, burnout, and nursing staff turnover. Therapeutic grade Lavender was found to help in the workplace to reduce stress in the nursing environment. Cited from Johnson et al., 2017, Intensive and Critical Care Nursing, vol 40, 18-25. DOI: 10.1016/j.iccn.2017.01.006

Aromatherapy Massage on pregnant women’s stress and immune system functions. Twenty-four pregnant women received a 70-minute massage with lavender aromatherapy every other week for twenty weeks and the control group received normal care.  The results showed lower salivary cortisol and higher salivary IgA present in the massage group on pre-post testing compared to control group. Aromatherapy can decrease stress and increase immune function. Cited from Chen et al., 2017, The Journal of Alternative and Complementary Medicine, vol 23(10), 778-786. Doi: 10.1089/acm.2016.0426

Lavender is known to reduce stress and anxiety as seen in a study with 122 critical condition patients. Reduction of anxiety with Lavender was also seen in patients waiting in a dental office. Massage with Lavender reduced the need for pain relievers in young HIV patients. These studies were mentioned in Prusinowska & Smigielski, 2014, Herba Polonica, vol 60(2).  DOI: 10.2478/hepo-2014-0010

Bug Repellant

Lavender has been used to repel moths and flies. Lavender compounds can get rid of mites from rabbits. Article title: Acaricidal agents of natural origin against Psoroptes cuniculi (parasite-mite). Cited from Perrucci et al.,1994, Parassitologia, Vol 36(3), 269-271. PMID: 7637996

Cancer Treatments

A cytotoxic study done on lung cancer showed lavender inhibited carcinogenic cell growth (Shou-Dong et el., 2009, Food Science Technology, 2, 213-215).

Lavender seed extract was shown to be probable cancer prevention and therapy from experiments with liver cancer cells by inhibiting cytotoxicity  Cited from Alshammari, G. M., 2022, PLoS ONE, vol 17(4), DOI: 10.1371/journal.pone.0267499

Saffron, lavender, clove, and red beet are being investigated to help with cancer treatments to diminish the harmful toxic side effects. The nanocomposite designs of phytomolecules from medicinal and aromatic plants: promising anticancer-antiviral applications. (Kaplan A., Beni-suef University Journal of Basic and Applied Sciences. 2022 ;11(1):17. DOI: 10.1186/s43088-022-00198-z. PMID: 35127958; PMCID: PMC8799966.

Prostate cancer in men is the second leading cause of death from cancer. Lavender was tested in vitro on the human prostate cancer PC-3 and DU145. The PC-3 cells were used to develop subcutaneous xenograft tumors with nude mice.  Lavender essential oil, linalool, and linalyl acetate showed stronger inhabitation on PC-3 than on the DU145 cells. Cell death from the treatments of the oil and compounds was noticed. The xenografts model with the PC-3 cells showed suppressed tumor growth with the oil treatments. This study showed an anti-tumor effect through cell proliferation inhibition and apoptosis in the tumor grafts. Cited from Zhao et al., 2017, Integrative Cancer Therapies, vol 16(2), 215-226. DOI: 10.1177/1534735416645408

Algerian Lavandula stoechas was used to test different cancer cell lines with the compound 1,8-Cineole (61.36%) which is an oxygenated monoterpene. The ear edema model reflected an anti-inflammatory response from the oil. The Lavandula oil was able to reduce paw edema. Histological analysis showed inhibition of the skin inflammatory response. This compound was found to be active against human gastric adenocarcinoma (AGS), melanoma (MV3), and breast carcinoma MDA-MB-231 cells with median inhibitory concentrations.

Cognitive Deficits

The effects of lavender’s compound linalool were studied against cognitive decline induced by D-Galactose and Aluminum Trichloride in mice. Alzheimer’s disease (AD) is a neurodegenerative disease of the brain. D-gal is reducing sugar in animals and can turn into hydrogen peroxide when in excess. This is seen in natural aging.  AlCl3, a neurotoxin, accelerates AD.  Oxidative stress is seen as a factor. Lavender has been found to give neuro and cognitive protection because of its linalool compound of 37.96% and linalyl acetate of 29.34%. Oxidative damage was decreased in the hippocampus and lavender oil protected the cortex. Linalool reversed the D-gal and AlCl3 in the hippocampus. Lavender oil protected the body’s Nrf2/HO-1 oxidative protection pathways. CaMKII, a key protein in the post-synaptic space for neuron communication, showed an increase with Linalool (100 mg/mL). Two other proteins needed for brain function are BDNF and TrkB which were found significantly higher due to the action of lavender oil on D-Gal and AlCI3.

Wound Healing

Skin wounds on rats were treated with lavender oil and were significantly decreased as compared to that of wounds of control rats at 4, 6, 8, and 10 days after wounding. Lavender oil induced expression of type I and III collagen at 4 days after wounding, accompanied by an increased number of fibroblasts, which synthesize collagen. TGF-β (transforming growth factor-Beta) in wounds treated with lavender oil was significantly increased as compared to control. Myofibroblasts (cells that help heal and repair damaged tissue) increase was observed in wounds treated with lavender oil at 4 days. The beneficial effect of lavender oil on wound healing may raise the possibility of innovative approaches as complementary treatment besides conventional therapy.
