English Lavender Flower Extract
Also known as: Lavandula angustifolia, English Lavender, Lavender
Overview
English Lavender Flower Extract is derived from the flowers of *Lavandula angustifolia*, a plant native to the Mediterranean region. It is highly valued for its calming and therapeutic properties, making it a popular ingredient in aromatherapy and dietary supplements. The extract contains volatile compounds such as linalool and linalyl acetate, which are believed to contribute to its anxiolytic and stress-reducing effects. Primarily, it is used to alleviate symptoms of anxiety, stress, insomnia, and mild depression. It is available in various forms, including essential oils for inhalation, oral supplements like Silexan, and topical applications. Research on lavender is extensive, with numerous studies exploring its effects on mental health and well-being. While the quality of evidence varies, systematic reviews and meta-analyses suggest that lavender can be a beneficial complementary treatment for reducing anxiety and stress.
Benefits
English Lavender Flower Extract is primarily recognized for its anxiolytic and stress-reducing benefits. Meta-analyses indicate that lavender inhalation significantly reduces anxiety levels (Hedges' g = -0.73, p < 0.00001). Oral administration of Silexan, a specific lavender oil supplement, has also demonstrated efficacy in reducing anxiety (Hamilton Anxiety Scale mean difference = -2.90, p = 0.004). Furthermore, lavender use is associated with a significant decrease in stress scores (SMD = 0.63 ± 0.13, p < 0.001). Some evidence suggests that lavender may help reduce symptoms of depression, though more research is needed to confirm these findings. Lavender has been shown to be particularly effective in reducing stress in student populations. The effect sizes for anxiety reduction are moderate to large, indicating clinical significance. Benefits can typically be observed within a few weeks of consistent use, depending on the method of administration.
How it works
Lavender's anxiolytic and stress-reducing effects are thought to be mediated through its interaction with the central nervous system. The active compounds in lavender, such as linalool and linalyl acetate, may influence GABA receptors and serotonin pathways, promoting relaxation and reducing stress responses. When inhaled, lavender essential oil is rapidly absorbed through the lungs, allowing for quick effects on the nervous system. Oral bioavailability is less well-studied but appears to be effective in certain formulations like Silexan. By modulating neurotransmitter activity and promoting a sense of calm, lavender helps to alleviate symptoms of anxiety and stress.
Side effects
English Lavender Flower Extract is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects (occurring in more than 5% of users) include gastrointestinal issues such as constipation and diarrhea when taken orally. Uncommon side effects (1-5%) may include headache and skin irritation. Rare side effects (less than 1%) have been reported, such as hormone-like effects in prepubescent males, potentially leading to breast growth. Lavender may interact with sedative medications, enhancing their effects, so caution is advised when combining lavender with other sedatives. It is contraindicated during pregnancy and breastfeeding due to insufficient safety data. Caution is also advised in children and individuals undergoing surgery. It is important to discontinue use and consult a healthcare provider if any adverse reactions occur.
Dosage
The optimal dosage of English Lavender Flower Extract varies depending on the method of administration and the specific product. For aromatherapy, there is no specific dose; it can be used as needed. For oral supplements like Silexan, the recommended dosage is typically 80-160 mg daily. The minimum effective dose is not well-established and may vary by application. High doses are generally not recommended without medical supervision. For aromatherapy, inhalation can be done directly or through a diffuser. For oral supplements, it is important to follow the product instructions. Bioavailability varies by method of administration, with inhalation providing rapid absorption. There are no identified required cofactors for lavender's efficacy.
