General Overview

Organic Litsea cubeba essential oil, also known as may chang or lemon litsea, is highly prized in artisanal soap making for its fresh, lemony, and floral fragrance, reminiscent of freshly picked lemon verbena from our gardens. This lively and uplifting scent lingers remarkably well in cold-process soaps, offering an invigorating and refreshing sensory experience—perfect for starting the day or brightening your mood in the shower.

Production Method

Litsea cubeba essential oil is obtained through steam distillation of the ripe fruits of a small tree native to Southeast Asia, primarily cultivated in China and Vietnam. This process yields a pale yellow oil with a distinctive aroma, while preserving the integrity of its active compounds.

Composition

The composition of Litsea cubeba essential oil is dominated by monoterpenes, mainly citral (a blend of neral and geranial, accounting for 62 to 87%), followed by D-limonene (8 to 15%), β-myrcene, α-pinene, β-pinene, linalool, and eucalyptol. Its high citral content is responsible for both its fragrance and its main biological properties.

Cosmetic and Food Uses

In cosmetics, this essential oil is valued for its antimicrobial, anti-inflammatory, astringent, and toning properties, making it particularly beneficial for combination to oily skin or skin prone to acne. Citral, its primary compound, has demonstrated antibacterial and antifungal activity, helping to purify the skin and limit microbial proliferation. It also helps regulate sebum production, tighten pores, and bring radiance to the complexion. Its anti-inflammatory effect has been studied for its role in modulating intestinal and skin inflammation, particularly through the reduction of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β). In food, it is used as a natural flavoring, but should be used with caution.

Precautions for Use

Like all essential oils, Litsea cubeba must be diluted before topical application to avoid irritation or sensitization. It is not recommended for pregnant or breastfeeding women, or for young children. The oil may cause allergic reactions, skin irritation, and severe eye reactions. In case of accidental ingestion, consult a doctor immediately. Always perform a patch test on the inner elbow before use.

Environmental Impact and Sustainability

The production of organic Litsea cubeba supports environmentally friendly agricultural practices. Steam distillation, which uses no solvents, ensures a pure oil, perfectly suited for committed cosmetics under the Nature & Progrès label.
