Rosemary (Rosmarinus officinalis) contains rosmarinic acid and carnosic acid that provide antioxidant and anti-inflammatory effects. These compounds work by scavenging free radicals and inhibiting inflammatory enzymes like lipoxygenase.
Origin & History
Rosemary (Rosmarinus officinalis L.) is an evergreen shrub native to the Mediterranean region, belonging to the Lamiaceae family. The leaves are extracted using various methods including water extraction, steam distillation for essential oil, and supercritical CO2 extraction, yielding phenolic compounds, flavonoids, and terpenes.
Research Narrative (Provisional)
The research dossier explicitly states that search results lack human clinical trials, RCTs, or meta-analyses on rosemary. Available data focus exclusively on in vitro mechanisms, particularly regarding SARS-CoV-2 spike protein interactions and ACE2 inhibition.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Fresh rosemary (per 100g): Calories ~131 kcal, Carbohydrates ~20.7g, Dietary fiber ~14.1g, Protein ~3.3g, Fat ~5.9g (predominantly unsaturated). Key micronutrients: Vitamin C ~21.8mg (24% DV), Vitamin A ~2924 IU, Folate ~109µg (27% DV), Vitamin B6 ~0.34mg, Iron ~6.65mg (37% DV), Calcium ~317mg (32% DV), Magnesium ~22mg, Manganese ~0.96mg (48% DV), Potassium ~668mg. Primary bioactive compounds: Carnosic acid (~1.5–2.5% dry weight, principal antioxidative diterpene), Carnosol (~0.2–0.9% dry weight, co-antioxidant diterpene), Rosmarinic acid (~0.5–2.0% dry weight, phenolic ester with anti-inflammatory properties), Ursolic acid (~0.5% dry weight, pentacyclic triterpenoid), 1,8-Cineole/Eucalyptol (~35–55% of essential oil fraction), α-Pinene (~15–25% of essential oil fraction), Camphor (~10–20% of essential oil fraction), Luteolin and apigenin (flavonoids, trace amounts ~0.01–0.05% dry weight). Bioavailability notes: Carnosic acid and carnosol are lipid-soluble; absorption enhanced when consumed with dietary fat. Rosmarinic acid demonstrates moderate oral bioavailability (~3–5% in human studies), with peak plasma levels at ~0.5–1 hour post-ingestion. Essential oil volatile compounds are highly bioavailable via inhalation and transdermal routes. Typical culinary use (~1–2g dried herb per serving) delivers micronutrients in modest but non-negligible quantities; therapeutic concentrations of phenolics generally require standardized extracts. Water extraction (as in teas or the studied aqueous extracts) preferentially concentrates rosmarinic acid and water-soluble phenolics over lipophilic diterpenes.
Reported Mechanism (Provisional)
Rosemary's primary bioactive compounds rosmarinic acid and carnosic acid act as potent antioxidants by donating hydrogen atoms to neutralize free radicals. These phenolic compounds also inhibit pro-inflammatory enzymes including lipoxygenase and cyclooxygenase. In vitro studies suggest rosemary water extract may interfere with viral protein binding by blocking ACE2 receptor interactions.
Clinical Narrative (Provisional)
Current evidence for rosemary comes primarily from in vitro laboratory studies rather than human clinical trials. One preliminary study showed rosemary water extract inhibited SARS-CoV-2 spike protein-ACE2 interaction by 72.9% and demonstrated up to 99.5% ACE2 activity inhibition at 5.0 mg RE/mL concentration. Animal studies have demonstrated antioxidant effects, but human clinical data remains limited. Most research focuses on rosemary's chemical constituents rather than clinical outcomes in people.
