Lemongrass Essential Oil

Lemongrass Essential Oil

A concentrated aromatic material from Cymbopogon citratus, obtained from grass leaves. The commercial oil is obtained by water/steam distillation of grass leaves. Harvest, drying, distillation and origin can alter chemistry; CO₂ extracts, absolutes and infused oils are not this entity.

Botany and aroma

The source taxon should be verified as Cymbopogon citratus (Poaceae). Plant part: grass leaves. Botanical name, plant part, process, origin and preferably batch analysis reduce identity errors. The profile is strong lemon, grassy, aldehydic. Characteristic volatiles may include citral: geranial and neral; proportions vary with chemotype, harvest, origin and processing. Chromatography is stronger identity evidence than odour copy alone.

History and culture

Tropical Asian and American cultivation supports culinary, household and perfume uses; its citral-rich oil is more concentrated than an herbal infusion. This is ethnobotanical and scent history, not a treatment claim. Historical tea, spice, resin or smoke use does not give the concentrated oil the same dose or risk profile.

Spiritual context

Esoteric and aromatic traditions associate it with road-opening, energetic clearing and Mercury. The recorded planetary correspondence is mercury; this is historical-symbolic classification, not a measured physical effect.

Practical use and safety

Diffusion should create a brief, intermittent aroma in a ventilated room, not saturate the air. Stop if headache, nausea, cough or discomfort occurs, and allow children and animals to leave. Topical use requires an appropriate carrier and a purpose- and person-specific safe dilution. Assess tolerance on a small area, discard oxidised oil and follow material-specific dermal limits. No drop, ml or percentage recipe is given here.

Do not apply neat; avoid eyes, mucosa and broken skin. Oxygen, heat and light promote oxidation and may increase sensitisation risk; store cool in a small, dark, tightly closed bottle and discard oxidised oil. Ingestion, adding drops to food and self-treatment are not recommended.
