# Salvia officinalis **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/salvia-officinalis **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 8 / 10 **Category:** European **Also Known As:** Salvia officinalis, Common Sage, Garden Sage, Culinary Sage, True Sage, Broad-leaved Sage, Kitchen Sage, Dalmatian Sage ## Overview Salvia officinalis (sage) contains rosmarinic acid and carnosic acid that inhibit [acetylcholine](/ingredients/condition/cognitive)sterase and HMG-CoA reductase enzymes. Clinical studies demonstrate significant cholesterol reduction and cognitive improvements in Alzheimer's patients. ## Health Benefits • Significantly reduces cholesterol and triglycerides: Meta-analysis of 4 RCTs showed total cholesterol reduction of 52.64 mg/dL and triglycerides by 74.98 mg/dL (Strong evidence) • Improves [cognitive function](/ingredients/condition/cognitive) in Alzheimer's disease: 4-month RCT in 42 patients showed significant improvements in ADAS-cog and CDR-SB scores (Moderate evidence) • Reduces PMS symptoms: RCT with 90 college students showed 23.42% reduction in symptom severity after 2 months (Moderate evidence) • Improves metabolic markers in PCOS: RCT with 70 women showed reduced triglycerides, improved HDL-cholesterol and [antioxidant](/ingredients/condition/antioxidant) capacity (Moderate evidence) • Enhances periodontal health: Split-mouth RCT showed significant reduction in bleeding on probing and pocket depth when used as adjunctive gel therapy (Moderate evidence) ## Mechanism of Action Sage's rosmarinic acid and carnosic acid inhibit acetylcholinesterase, increasing acetylcholine levels for enhanced [cognitive function](/ingredients/condition/cognitive). These compounds also suppress HMG-CoA reductase activity, reducing cholesterol synthesis. Additionally, sage monoterpenes activate GABA receptors and modulate calcium channels in neural tissue. ## Clinical Summary A meta-analysis of 4 randomized controlled trials demonstrated sage supplementation reduces total cholesterol by 52.64 mg/dL and triglycerides by 74.98 mg/dL. A 4-month RCT in 42 Alzheimer's patients showed significant improvements on the ADAS [cognitive](/ingredients/condition/cognitive) assessment scale. Most studies used standardized sage extracts at 300-600mg daily. Evidence is strongest for lipid-lowering effects, with emerging support for cognitive benefits. ## Nutritional Profile Salvia officinalis (common sage) contains per 100g dried leaf: Protein ~10.6g, Total fat ~12.7g (including alpha-linolenic acid ~4.7g, linoleic acid ~1.8g), Total carbohydrates ~60.7g, Dietary fiber ~40.3g. Key micronutrients per 100g: Vitamin K ~1714µg (1428% DV - highest nutritional highlight), Vitamin A ~590µg RAE, Vitamin C ~32.4mg, Vitamin B6 ~2.69mg, Iron ~28.1mg, Calcium ~1652mg, Magnesium ~428mg, Manganese ~3.13mg, Potassium ~1070mg. Primary bioactive compounds: Rosmarinic acid (~3-5% dry weight, strong [antioxidant](/ingredients/condition/antioxidant) and [anti-inflammatory](/ingredients/condition/inflammation)), Carnosic acid (~1.5-3% dry weight, [neuroprotective](/ingredients/condition/cognitive), lipid [metabolism](/ingredients/condition/weight-management) modulator), Carnosol (~0.2-0.5% dry weight, anti-inflammatory), Ursolic acid (~0.3-0.6% dry weight), Oleanolic acid (~0.1-0.3% dry weight). Essential oil constituents (~1.5-2.5% of dry leaf): α-thujone (18-43%), β-thujone (3-8.5%), camphor (4.5-24.5%), 1,8-cineole (5.5-13%), borneol (~16%). Flavonoids: Luteolin (~0.5-1mg/g dry weight), Apigenin, Quercetin derivatives. Bioavailability notes: Rosmarinic acid demonstrates good oral bioavailability (~1.7% absorbed in human studies); carnosic acid undergoes extensive first-pass hepatic metabolism converting to carnosol and methyl carnosate; fat-soluble diterpenes (carnosic acid, carnosol) have enhanced absorption when consumed with dietary fat; thujone content is dose-dependent and intake should be moderated (WHO suggests limiting thujone intake to <3mg/day); typical culinary use (~1-4g dried herb per serving) delivers approximately 5-20mg rosmarinic acid per serving. ## Dosage & Preparation Clinically studied dosages include: Hydroalcoholic extract 330 mg/day for metabolic conditions (8 weeks), capsules 500 mg/day for PMS (2 months), fixed-dose extract for Alzheimer's (4 months, specific mg not reported), and topical gel for periodontal conditions. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Sage is generally well-tolerated at therapeutic doses under 600mg daily for up to 4 months. High doses may cause seizures due to thujone content, particularly in epileptic individuals. Sage may enhance effects of diabetes medications and anticoagulants like warfarin. Pregnant and breastfeeding women should avoid therapeutic doses due to uterine stimulant properties. ## Scientific Research Clinical evidence includes a meta-analysis of 4 RCTs demonstrating significant lipid improvements (PMID: meta-analysis not specified), and individual RCTs showing benefits for PCOS (PMID: 40141012), PMS (PMID: 30572339), Alzheimer's disease (PMID: 12605619), and periodontitis (PMID: 38765348). Studies consistently demonstrate good tolerability with minimal side effects compared to placebo. ## Historical & Cultural Context Sage has been used for centuries in Mediterranean and global traditional medicine systems, including ancient Greek, Roman, and Persian traditions, for metabolic disorders, hyperlipidemia, diabetes, digestive issues, [inflammation](/ingredients/condition/inflammation), and women's health. Its traditional use as an [antioxidant](/ingredients/condition/antioxidant) and metabolic regulator aligns with modern clinical findings. ## Synergistic Combinations Berberine, Omega-3 fatty acids, Curcumin, Green tea extract, Ginkgo biloba ## Frequently Asked Questions ### How much sage should I take for cholesterol? Clinical studies showing cholesterol reduction used 300-600mg of standardized sage extract daily. Most effective doses were 500mg taken twice daily with meals for at least 8 weeks. ### Can sage help with memory loss? Yes, sage extract improved cognitive scores in Alzheimer's patients after 4 months of 300mg twice daily. The rosmarinic acid in sage inhibits acetylcholinesterase, the same target as Alzheimer's medications. ### What are sage's side effects? Common side effects include mild digestive upset and dizziness at doses above 600mg daily. High doses may cause seizures due to thujone content, especially in people with epilepsy. ### Does sage interact with medications? Sage may enhance blood-thinning effects of warfarin and increase hypoglycemic effects of diabetes medications. It may also interact with seizure medications due to its effects on GABA receptors. ### How long does sage take to work for cholesterol? Cholesterol-lowering effects typically appear within 4-8 weeks of consistent sage supplementation. Peak benefits occurred at 12 weeks in clinical trials using 500mg twice daily. ### Is sage safe to take during pregnancy or while breastfeeding? Sage is generally not recommended during pregnancy due to limited safety data and its traditional use as a menstrual stimulant, which could potentially affect pregnancy. While breastfeeding, sage use should be discussed with a healthcare provider, as some compounds may pass into breast milk and effects on nursing infants are not well-established. ### What form of sage is most effective—fresh, dried, tea, or extract supplement? Standardized sage extracts used in clinical research have shown the strongest evidence for cholesterol and cognitive benefits, typically containing concentrated phenolic compounds. Dried sage tea and culinary preparations contain bioactive compounds but at lower concentrations than standardized supplements, making extracts more reliable for therapeutic dosing. ### How strong is the clinical evidence for sage compared to prescription cholesterol medications? Meta-analysis data shows sage reduces total cholesterol by approximately 52.64 mg/dL, which is modest compared to statins that typically reduce cholesterol by 30-50%, though effects vary by individual. Sage may be considered a complementary dietary approach rather than a replacement for prescription medications, particularly for significant cholesterol elevation. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
