Lemon Grass
Also known as: lemongrass, West Indian lemongrass, citronella grass, Cymbopogon citratus
Overview
Lemongrass stalk extract is derived from the stalks of *Cymbopogon citratus*, a tropical grass native to Asia, recognized for its aromatic and culinary attributes. This extract is rich in citral, an essential oil component known for its fragrance and potential therapeutic effects. Historically, lemongrass has been used for various medicinal purposes including digestion support and fever reduction. While its essential oil is extensively studied, research on the specific therapeutic properties of the stalk extract itself is limited. Some suggest that lemongrass extract may promote antioxidant, anti-inflammatory, and antimicrobial activities, indicating potential health benefits. However, the majority of current evidence is observational or experimental, indicating a gap in rigorous clinical trials specific to the stalk extract.
Benefits
Lemongrass stalk extract is believed to possess antioxidant, anti-inflammatory, and antimicrobial properties. These benefits may enhance wound healing and support digestive health, although rigorous studies specifically focused on the stalk extract are lacking. Current evidence largely stems from findings related to lemongrass essential oil, which shows promise in skin health improvement and relaxation effects in aromatherapy. It's recognized that certain populations could benefit from lemongrass extract, but further investigation is required to pinpoint specific therapeutic advantages and effectiveness for different groups.
How it works
The efficacy of lemongrass stalk extract is attributed mostly to citral, its primary active compound. Citral is thought to modulate biological pathways that influence inflammatory responses and combat oxidative stress. The extract may enhance the body's antioxidant defenses and possess antimicrobial properties, contributing to its health-promoting aspects. That said, the precise molecular interactions and mechanisms of action of lemongrass stalk extract remain inadequately explored, indicating a need for further studies to clarify its role in interaction with the immune and integumentary systems.
Side effects
Lemongrass stalk extract is generally deemed safe when used as intended, although adverse effects can occur. Skin irritation and allergic reactions may arise, particularly when using concentrated essential oil. Consumption of excessive amounts can lead to gastrointestinal discomfort. There are potential drug interactions, especially with anticoagulants and diabetes medications due to effects on blood sugar levels and coagulation processes. Caution is recommended during pregnancy and breastfeeding due to insufficient safety data. Special populations, including children and those with sensitive skin, should use lemongrass extract judiciously.
Dosage
Currently, there are no definitive dosage guidelines specifically for lemongrass stalk extract. However, the essential oil is frequently used in small doses for aromatherapy or dietary supplementation, often recommended in diluted form to prevent skin irritation. Recommended dosages may vary according to the type of extract used. Because there are no established maximum safe doses, it is advised to adhere to general usage guidelines and seek personalized advice from a healthcare professional before use.
