Hermetica Superfood Encyclopedia
Rosmarinus officinalis (rosemary) extract contains bioactive compounds including rosmarinic acid and carnosic acid that demonstrate antioxidant properties. These polyphenolic compounds work by scavenging free radicals and inhibiting lipid peroxidation pathways.
Origin & History
Rosmarinus officinalis L. is a perennial woody herb native to the Mediterranean region that produces polyphenolic compounds as secondary metabolites, particularly carnosic acid and rosmarinic acid. It is extracted using various methods including ultrasound-assisted extraction, supercritical fluid extraction with CO₂, Soxhlet extraction, and traditional decoction, each yielding different chemical profiles.
Scientific Research
The provided research dossier does not contain specific human clinical trials, randomized controlled trials, or meta-analyses with PubMed PMIDs. The available sources focus on extraction methodology optimization and chemical composition analysis rather than clinical efficacy studies.
Preparation & Dosage
The research does not provide clinically studied dosage ranges for rosemary extract or standardization protocols used in human studies. The extraction studies describe laboratory parameters but not clinical dosing recommendations. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Rosmarinus officinalis (rosemary) contains a well-characterized array of bioactive compounds, though nutritional contribution is typically minor given culinary use quantities (1-2g dried herb per serving). Key bioactive polyphenols include rosmarinic acid (approximately 1.5-3.8% dry weight), carnosic acid (1.5-2.5% dry weight, highest among lamiaceae herbs), and carnosol (0.2-0.5% dry weight) - these three compounds account for the primary antioxidant activity noted in extraction studies. Essential oil fraction (1-2.5% dry weight) contains 1,8-cineole/eucalyptol (30-55% of oil), camphor (10-25% of oil), and alpha-pinene (10-20% of oil). Flavonoid content includes luteolin, apigenin, and genkwanin at trace concentrations (combined approximately 0.1-0.3% dry weight). Micronutrient content per 100g dried herb: vitamin C approximately 61mg, vitamin A approximately 590 IU, calcium approximately 1280mg, iron approximately 29mg, magnesium approximately 220mg, manganese approximately 1.9mg. Dietary fiber approximately 42g per 100g dried weight. Protein approximately 5g per 100g. Bioavailability note: carnosic acid and rosmarinic acid demonstrate moderate oral bioavailability, though concentrations achieved from food-level consumption are substantially lower than those used in the extraction studies referenced in the existing research dossier, limiting direct translation of in-vitro antioxidant findings to physiological outcomes.
How It Works
Rosmarinic acid and carnosic acid in rosemary extract function as phenolic antioxidants by donating hydrogen atoms to neutralize free radicals. These compounds inhibit lipid peroxidation by breaking oxidative chain reactions and chelating metal ions. The diterpenes also modulate antioxidant enzyme systems including catalase and superoxide dismutase.
Clinical Evidence
Current research on Rosmarinus officinalis focuses primarily on extraction methods and in vitro antioxidant capacity rather than human clinical outcomes. Laboratory studies demonstrate significant free radical scavenging activity with DPPH and ABTS assays. Human clinical trials investigating specific health benefits are limited, with most evidence remaining at the preliminary laboratory stage. The therapeutic potential requires validation through controlled human studies with standardized extracts.
Safety & Interactions
Rosemary extract is generally recognized as safe when used as a food flavoring agent. High doses may cause gastrointestinal irritation, kidney irritation, or uterine contractions. Rosemary may interact with anticoagulant medications due to potential effects on blood clotting. Pregnant and breastfeeding women should avoid therapeutic doses beyond culinary use due to potential uterine stimulant effects.
