Glossary
An essential oil steam-distilled from the leaves and stalks of lemongrass (Cymbopogon citratus) that has multiple applications in both skincare and beekeeping. In skincare, lemongrass oil is used for its antimicrobial and astringent properties. In beekeeping, it mimics the Nasonov pheromone that scout bees use to guide swarms, making it an effective swarm lure.
Lemongrass oil contains 65-85 percent citral (a combination of geranial and neral), which provides potent antimicrobial activity against bacteria and fungi. Research has shown effectiveness against acne-causing bacteria (P. acnes) and the Malassezia yeast associated with dandruff and seborrheic dermatitis.
In skincare formulations, lemongrass oil is used at 0.5-2 percent concentration for its antimicrobial, astringent, and deodorizing properties. It has a fresh, clean citrus scent that adds a natural fragrance to products. Caution: lemongrass oil can be irritating at concentrations above 2 percent and should be used with care on sensitive skin.
Lemongrass oil closely mimics the chemical composition of the Nasonov pheromone, particularly geraniol and citral, that scout bees release to guide swarm clusters to suitable new nest cavities. Applying a few drops of lemongrass oil to a swarm trap or bait hive significantly increases its attractiveness to passing swarms.
Beekeepers commonly place 2-3 drops of lemongrass oil on a cotton ball inside a swarm trap positioned 6-15 feet above ground in an area with active bee populations. The scent can attract scout bees from considerable distances.
At proper dilutions (0.5-2 percent in a carrier oil), lemongrass oil is generally safe for most skin types. However, it can be irritating at higher concentrations and may cause photosensitivity. Patch test before facial use. Avoid during pregnancy.
Yes. The citral and geraniol in lemongrass oil closely mimic the Nasonov pheromone that scout bees use to mark potential nest sites. Field evidence strongly supports lemongrass oil as one of the most effective natural swarm attractants available to beekeepers.
No. Lemongrass (Cymbopogon) is a tropical grass with a strong citrus scent. Lemon balm (Melissa officinalis) is a temperate herb in the mint family with a gentler lemon scent. They have different chemical profiles and different skincare and beekeeping applications.
