Hermetica Superfood Encyclopedia
Lemongrass (Cymbopogon citratus) extract contains citral and geraniol as primary bioactive compounds that activate caspase-3 pathways to induce apoptosis in cancer cells while inhibiting Src-tyrosine kinase phosphorylation. The extract demonstrates potent enzyme inhibition, including 57.19 mg kojic acid equiv./g tyrosinase inhibition and 2.40 mmol acarbose equiv./g α-glucosidase inhibition.
Health Benefits
Origin & History
Lemongrass (Cymbopogon citratus) is an aromatic grass native to South and Southeast Asia, thriving in tropical and subtropical climates. It has been revered across Ayurveda, Traditional Chinese Medicine (TCM), and Thai herbalism for centuries. Rich in citral, flavonoids, and polyphenols, lemongrass is valued for its antimicrobial, digestive, and detoxifying benefits, making it a staple in functional nutrition and wellness.
Scientific Research
Clinical research supports Lemongrass's role in digestive enzyme activation, antimicrobial and immune-boosting properties, and blood sugar regulation. Studies also highlight its cardiovascular protective effects, lipid metabolism support, and anti-inflammatory and detoxification pathways, primarily through its rich phytochemical profile.
Preparation & Dosage
Nutritional Profile
- Vitamin C: Supports immune function and collagen synthesis. - Potassium, Calcium, Magnesium: Aid nerve function, circulation, and muscle relaxation. - Citral (Geranial and Neral): Potent antimicrobial, antifungal, and anti-inflammatory compound. - Flavonoids and Polyphenols: Protect against oxidative stress and support cardiovascular health. - Limonene and Myrcene: Enhance antioxidant activity and support respiratory health. - Terpenes (Beta-caryophyllene, Linalool): Support mood balance and stress resilience.
How It Works
Citral (geranial and neral) activates caspase-3 to induce DNA fragmentation and apoptosis in cancer cells while inhibiting Src-tyrosine kinase phosphorylation at Y416, reducing Stat3 activation and antiapoptotic proteins Bcl-xL/Mcl-1. Geraniol triggers mitochondrial apoptosis by upregulating pro-apoptotic proteins and suppresses angiogenesis via VEGFR-2 downregulation. The extract's antimicrobial effects occur through membrane disruption, while neuroprotective actions reduce lipid peroxidation markers MDA/NO and boost antioxidant enzymes GSH/CAT.
Clinical Evidence
Current evidence is primarily based on in vitro and animal studies rather than human clinical trials. Laboratory studies demonstrate significant enzyme inhibition activity, with volatile oil showing 57.19 mg kojic acid equiv./g tyrosinase inhibition and n-hexane extract showing 1.53 mg galanthamine equiv./g BChE inhibition. Animal models show restored antioxidant markers including reduced MDA/NO levels and increased GSH/CAT activity in neuroprotection studies. Human clinical trial data with specific quantified outcomes are currently lacking and needed to confirm therapeutic efficacy.
Safety & Interactions
Research indicates low cytotoxicity for lemongrass compounds like luteolin glycosides, with studies showing general safety without adverse effects flags. However, comprehensive safety data including specific drug interactions, contraindications, and pregnancy safety profiles are not well-established in current literature. As with all herbal extracts, potential interactions with medications metabolized by cytochrome P450 enzymes should be considered. Clinical supervision is recommended, particularly for individuals with diabetes taking glucose-lowering medications, given the extract's demonstrated effects on α-amylase and α-glucosidase enzymes.
