Rosemary Supercritical Extract
Also known as: Rosemary, Rosemary extract, Rosmarinus, Carnosic acid, Carnosol, Rosmarinic acid, Rosmarinus officinalis
Overview
Rosemary (*Rosmarinus officinalis*) is a perennial herb native to the Mediterranean region, renowned for its aromatic needle-like leaves and extensive culinary uses. Recently, it has gained attention for its medicinal properties, particularly when extracted using supercritical fluid extraction (SFE), yielding concentrated forms enriched with bioactive compounds such as carnosic acid, carnosol, and rosmarinic acid. These compounds exhibit potent antioxidant, anti-inflammatory, and antimicrobial activities. Research backs the broad health benefits attributed to rosemary extract, including its role in reducing oxidative stress and promoting general wellness. Systematic reviews and clinical investigations further attest to its efficacy, highlighting the extract's potential in various health applications.
Benefits
Rosemary extract is primarily recognized for its robust antioxidant capacity, effectively scavenging free radicals and minimizing oxidative stress. Clinical research shows it positively influences chronic inflammation, though varying efficacy is reported, especially in cases like postintubation sore throat. The extract also demonstrates antimicrobial activity against various pathogens, predominantly Gram-positive bacteria. While it is broadly acknowledged for mitigating oxidative damage, more extensive research is needed to clarify its clinical applications for specific medical conditions. High-quality clinical trials and in vitro studies underscore its medicinal potential, indicating that rosemary extract may have a place in both preventive and therapeutic health regimens.
How it works
Rosemary extract performs through multiple biological mechanisms. Its antioxidant properties arise from the neutralization of free radicals, while its anti-inflammatory effects involve inhibiting inflammatory mediators. The extract's antimicrobial action stems from disrupting the cell membranes of pathogens. Key phytochemicals, notably carnosic acid and carnosol, enhance immune responses and potentially benefit gastrointestinal health. The supercritical fluid extraction (SFE) process augments the solubility and bioavailability of these active compounds, improving their therapeutic efficacy and facilitating absorption in the body.
Side effects
Rosemary extract is generally safe for most individuals when used as directed, with mild side effects such as gastrointestinal discomfort or allergic reactions noted in fewer than 5% of users. Serious allergic responses and rare drug interactions, particularly with anticoagulant medications, have been documented. Additional caution is warranted for pregnant or breastfeeding women and individuals with epilepsy or hypertension; these individuals should seek medical advice before use. The available data on long-term safety and specific adverse effects are limited, emphasizing the need for responsible consumption and consultation with healthcare professionals when necessary.
Dosage
The recommended dosage of rosemary extract varies based on health outcomes sought. For antioxidant effects, a minimum daily dosage of 100-200 mg is advised, while optimal dosages for broader health benefits generally range from 200-1000 mg per day. Caution is advised for dosages exceeding 1000 mg as the safety profile in such cases remains unclear. The timing of intake should complement health objectives; antimicrobial effects may be observed relatively soon after consumption, whereas antioxidant benefits accumulate over time. Extracts derived from supercritical fluid extraction are favored for their enhanced absorption and overall efficacy.
FAQs
Is rosemary extract safe to use?
