Alfazema Extract
Also known as: Alfazema, Lavender extract, Lavandula angustifolia
Overview
Alfazema extract, primarily derived from the Lavandula angustifolia plant, is a herbal supplement widely utilized in traditional medicine and aromatherapy. It is rich in essential oils, notably linalool and linalyl acetate, which are believed to contribute to its therapeutic properties. Historically, it has been employed for its purported anti-inflammatory, anxiolytic, antimicrobial, and skin-soothing effects. While research on alfazema extract is moderately developed, with numerous studies exploring its topical applications for skin conditions and aromatherapeutic benefits, high-quality systematic reviews specifically on its efficacy are limited. The evidence base is often mixed or insufficient for making strong clinical recommendations, particularly concerning standardized usage and efficacy in specific conditions.
Benefits
Some preliminary evidence suggests that herbal medicines, including lavender extracts, may offer benefits in improving symptoms of atopic dermatitis (AD) when applied topically or used systemically. These benefits may include reducing itching, alleviating inflammation, and enhancing the overall quality of life for individuals with AD. However, a systematic review focusing on topical herbal medicines for atopic eczema concluded that there is insufficient evidence to definitively confirm the efficacy of any single herbal extract, including lavender. This limitation is largely due to the heterogeneity and methodological flaws present in many of the existing studies. While lavender oil is also investigated for its anxiolytic and mild sedative properties, these effects are outside the scope of its dermatological applications. The precise effect sizes and clinical significance of alfazema extract in skin conditions remain unclear due to the absence of large, rigorous randomized controlled trials (RCTs).
How it works
Alfazema extract exerts its effects primarily through its volatile compounds, such as linalool and linalyl acetate, which possess anti-inflammatory and antimicrobial properties. These compounds are thought to modulate inflammatory pathways within skin cells and reduce oxidative stress, thereby contributing to the relief of symptoms associated with conditions like dermatitis. The extract's active components are absorbed mainly through topical application to the skin or via inhalation during aromatherapy. The bioavailability of these compounds can vary depending on the specific formulation and method of administration.
Side effects
Alfazema extract is generally considered safe when used topically or in aromatherapy at recommended dosages. The most commonly reported side effects are mild skin irritation or allergic reactions, particularly in individuals with sensitive skin. There are no significant drug interactions or contraindications consistently reported in high-quality scientific literature. However, caution is advised regarding its use in special populations, such as pregnant women and young children, due to limited available data on safety in these groups. Patch testing is recommended before widespread topical application to identify potential allergic reactions.
Dosage
There is currently no standardized dosing established for alfazema extract, particularly for dermatological conditions, due to insufficient robust clinical trial data. For topical applications, typical formulations often utilize diluted essential oil concentrations, generally ranging from 1% to 5%. The timing and duration of use can vary significantly depending on the specific product and the intended indication. Clinical trials investigating alfazema extract have shown durations ranging from several weeks to a few months. Due to the lack of standardized research, specific upper limits or safety thresholds for internal use are not well-defined, emphasizing the importance of following product-specific guidelines and consulting healthcare professionals.
FAQs
Is alfazema extract effective for eczema?
Current evidence is insufficient to confirm the efficacy of alfazema extract for eczema. More rigorous randomized controlled trials are needed to establish its effectiveness.
Is alfazema extract safe to use?
Alfazema extract is generally considered safe for topical use. However, patch testing is recommended to prevent potential allergic reactions in sensitive individuals.
How should I use alfazema extract?
Alfazema extract is typically applied topically in a diluted form. For aromatherapy, it is used via inhalation. Always follow product-specific instructions.
When can I expect to see results from using alfazema extract?
There is no clear timeline for results due to the lack of standardized studies. Effects can vary based on individual response and the specific condition being addressed.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC7382724/ – This overview of systematic reviews and reanalysis of RCTs on herbal medicine for atopic dermatitis found that herbal medicines, including lavender, showed better efficacy than placebo in AD symptom relief with comparable safety. However, the study noted low methodological quality and moderate to very low quality evidence, emphasizing the need for further high-quality RCTs.
- https://pubmed.ncbi.nlm.nih.gov/27373699/ – This systematic review on topical herbal medicines for atopic eczema concluded that there is insufficient evidence to confirm the efficacy of any single herbal extract, including lavender. The review highlighted significant heterogeneity, small sample sizes, and methodological flaws in the included studies, preventing a meta-analysis.
- https://onlinelibrary.wiley.com/doi/abs/10.1111/bjd.14840 – This source, likely related to the Santer et al. 2016 systematic review, further details the limitations of existing research on topical herbal medicines for atopic eczema. It underscores the lack of robust evidence for lavender and other herbal extracts due to methodological issues and small cohorts.
- https://www.frontiersin.org/journals/medicine/articles/10.3389/fmed.2024.1337785/full – This systematic review on essential oils (general) identified various bioactive compounds with anti-inflammatory and antioxidant effects, using examples like cinnamon oil. While providing preliminary evidence for the potential of essential oils, it noted that most findings were preclinical, indicating a need for more human randomized controlled trials and translational research.
