Thyme Herb Extract
Also known as: *Thymus vulgaris L.*, *Thymus serpyllum L.*, Thyme, Garden Thyme, Wild Thyme, *Thymus vulgaris*
Overview
Thyme is a perennial herb derived primarily from the leaves of the *Thymus* genus, especially *Thymus vulgaris* (common thyme) and *Thymus serpyllum* (wild thyme). Native to the Mediterranean region, it has been widely used in culinary, medicinal, and antiseptic applications. Rich in essential oils and non-volatile compounds like phenolic acids and flavonoids, thyme is noted for its potential health benefits, including antimicrobial, anti-inflammatory, and antitussive properties. Despite its extensive use, much of the existing evidence comes from preclinical studies, and further rigorously designed clinical trials are necessary to establish its efficacy and safety in human populations, although some randomized controlled trials exist. Current evidence indicates that thyme may aid in treating respiratory infections, coughs, and digestive issues.
Benefits
Thyme has several evidence-based benefits: - **Antitussive and Anti-inflammatory Effects**: A study involving 749 patients showed significant improvements in cough severity (improvement from 8.7 to 2.4 on the Bronchitis Severity Score) and health-related quality of life (HRQoL), with an 87.2% response rate for cough relief. - **Cardio-Metabolic Effects**: Animal studies suggest thyme extracts may improve lipid profiles and reduce cholesterol levels, which require confirmation through human trials. - **Antimicrobial Effects**: It has shown efficacy against various bacteria and fungi. - **Hepatoprotective Effects**: Preclinical studies suggest potential benefits for liver protection, although human studies are needed. Particularly, individuals with respiratory issues, such as acute cough, may benefit from thyme supplementation based on observational studies.
How it works
Thyme's medicinal properties are largely attributed to its essential oils and non-volatile compounds, which interact with anti-inflammatory, antimicrobial, and antioxidant pathways. It modulates the immune system, reduces inflammation, and exerts antimicrobial activity against pathogens in the respiratory and gastrointestinal tracts. The phenolic acids and flavonoids in thyme target various molecular pathways involved in inflammation and oxidative stress, enhancing its therapeutic effects. The bioavailability of its active compounds varies based on the supplement's form and other ingredient interactions.
Side effects
Thyme is generally considered safe for most individuals when used in recommended doses. No common side effects (>5% occurrence) have been reported in available studies. Uncommon side effects (1-5%) and rare side effects (<1%) have also not been documented in peer-reviewed literature. Limited evidence exists regarding potential drug interactions, particularly with medications affecting the liver or immune system. Caution should additionally be exercised in individuals with allergies to thyme or related herbs from the Lamiaceae family. Pregnant or breastfeeding women are advised to consult healthcare providers prior to using thyme supplements due to insufficient safety data in these populations.
Dosage
The effective dosage of thyme depends on the specific preparation and intended use. For respiratory issues, the thyme/ivy combination (BNO 1200) has been used until cough resolution, with a mean duration of treatment around 7 days. While no maximum safe dose has been set, it is advisable to approach high doses with caution. Thyme can be consumed in various forms such as essential oil, extract, or whole herb, with bioavailability being influenced by preparation. There are no specific cofactors required for optimal use, but maintaining a balanced diet can enhance its efficacy.
