Lavender Aerial Extract
Also known as: Lavender, English lavender, Sweet lavender, Lavandula latifolia, Lavandula × intermedia, Lavandula angustifolia
Overview
Lavender aerial extract is derived from the flowers of the lavender plant, primarily _Lavandula angustifolia_, _Lavandula latifolia_, and _Lavandula × intermedia_. Known for its calming and therapeutic properties, this herbal supplement is used widely in aromatherapy and as a natural remedy for anxiety, depression, and stress reduction. Lavender’s bioactive compounds, particularly linalool and linalyl acetate, contribute to its therapeutic effects. The extract can be administered through inhalation, topical application, or oral consumption, and research on lavender is robust, with numerous studies affirming its efficacy in various clinical populations. While the evidence is strong, findings suggest variability due to potential study limitations such as high heterogeneity and risk of bias.
Benefits
Lavender is well-documented for several benefits: (1) **Anxiety Reduction** - Significant reduction in anxiety levels via inhalation, with a Hedges' g of -0.73 (p < 0.00001); (2) **Depression Reduction** - Demonstrated antidepressant properties, showing a pooled Standardized Mean Difference (SMD) of -0.66 (p < 0.001); (3) **Stress Reduction** - Effectively lowers stress scores, evidenced by a SMD of 0.63 ± 0.13 (p < 0.001). These benefits extend across diverse populations, including surgery patients, critically ill individuals, and pregnant women, suggesting broad applicability in both clinical and everyday settings.
How it works
The therapeutic effects of lavender are primarily attributed to its bioactive compounds such as linalool and linalyl acetate. These compounds engage with the central nervous system by influencing the GABAergic system, which is crucial in modulating anxiety and stress responses. Lavender's compounds are quickly absorbed when inhaled, facilitating immediate anxiolytic effects, while topical applications allow for absorption through the skin, providing further therapeutic benefits.
Side effects
Lavender is generally safe for most individuals; however, there are some potential side effects to consider. Common side effects are minimal, with studies reporting low withdrawal rates. Uncommonly, allergic reactions or skin irritations may arise with topical applications. No rare side effects have been well-documented. Caution is advised concerning interactions with sedatives or central nervous system depressants as lavender may enhance their effects. Pregnant or breastfeeding women should use it judiciously due to limited and inconclusive research. Children and older adults can safely use lavender, but dosages should be tailored appropriately.
Dosage
The recommended minimum effective dose for lavender varies by usage method. For inhalation, 2-5 drops of essential oil applied for 3-20 minutes is effective for reducing anxiety and stress. Long-term benefits for depression may be achieved with 3 drops on a cotton ball used consistently over 30 nights. While there is no established maximum safe dose, caution is advised against excessive use due to possible interactions and allergic reactions. Consistent practice, particularly inhalation, is recommended for optimal results.
