Lemongrass extract contains citral as its primary bioactive compound, which demonstrates antimicrobial and anti-inflammatory properties. The extract works by inhibiting bacterial cell wall synthesis and modulating inflammatory pathways to support digestive health and immune function.
Origin & History
Native to South and Southeast Asia, lemongrass (Cymbopogon citratus) thrives in tropical and subtropical climates with well-drained, nutrient-rich soils. Revered across Ayurveda, Traditional Chinese Medicine (TCM), and Thai herbalism, lemongrass has long been used for its antimicrobial, digestive, and detoxifying benefits. Rich in citral, flavonoids, and polyphenols, lemongrass extract delivers potent anti-inflammatory, metabolic, and immune-enhancing effects. Today, it is widely incorporated into functional nutrition, herbal teas, and aromatherapy formulations for its refreshing, revitalizing properties.
Scientific Research
Supported by clinical research on digestive enzyme activation (PubMed), antimicrobial and immune-boosting properties (Food Chemistry), blood sugar and metabolic regulation (ScienceDirect), cardiovascular protection and lipid metabolism (Frontiers in Pharmacology), and anti-inflammatory and detoxification pathways (PMC).
Preparation & Dosage
Traditional: Used in Ayurveda as a digestive and detoxifying tonic, often prepared as herbal teas or infused oils. In TCM, lemongrass was consumed to clear internal heat and support inflammatory balance. Thai herbalism utilized lemongrass for fever reduction, immune support, and digestive health. Modern: Found in essential oil, tincture, and standardized powdered extract forms, widely used in digestive health supplements, immune defense blends, detox formulations, and metabolic support products. Also incorporated into functional teas, wellness tonics, and aromatherapy. Dosage: 500–1,500mg extract daily, or 1–3g dried lemongrass infused in teas for gut, immune, and metabolic health.
Nutritional Profile
Rich in citral (antimicrobial and anti-inflammatory action), flavonoids (immune and metabolic regulation), polyphenols (cardiovascular and antioxidant support), geraniol (digestive and liver detox benefits), limonene (oxidative stress protection), vitamin C (immune function and collagen synthesis), and potassium (electrolyte balance and cardiovascular health).
How It Works
Citral, comprising 65-85% of lemongrass essential oil, disrupts bacterial cell membrane integrity and inhibits biofilm formation. The compound modulates NF-κB inflammatory pathways while stimulating digestive enzyme secretion through cholinergic receptor activation. Flavonoids like luteolin enhance antioxidant activity by scavenging free radicals and supporting cellular glutathione production.
Clinical Evidence
Human studies on lemongrass extract remain limited, with most evidence derived from in vitro and animal research. A 2012 study of 60 participants showed 200mg daily reduced bloating symptoms by 40% over 4 weeks. Antimicrobial studies demonstrate MIC values of 0.5-2.0 mg/mL against common pathogens including E. coli and Candida albicans. While preliminary research shows promise for blood sugar regulation, larger randomized controlled trials are needed to confirm therapeutic efficacy.
Safety & Interactions
Lemongrass extract is generally well-tolerated at typical doses of 100-300mg daily, though some individuals may experience mild gastrointestinal upset. The extract may enhance effects of anticoagulant medications due to its blood-thinning properties. Pregnant and breastfeeding women should avoid supplementation as safety data is insufficient. Individuals with citrus allergies should exercise caution as cross-reactivity may occur.
