Lemongrass (Cymbopogon citratus) (Cymbopogon flexuosus)

A mini profile of lemongrass will be found on the main website and a more in depth profile is to be found in the Aromatherapy 201 course notes.  Cymbopogon citratus West Indian Lemongrass and Cymbopogon flexuosus East Indian Lemongrass are both members of the Gramineae family.   Lemongrass is a fast-growing perennial grass native to India and grows to a height of up to 5-feet and has yellow-golden leaves and stems. Its production of a network of roots and rootlets, can rapidly exhaust the soil.

Lemongrass is used quite extensively as a flavor ingredient throughout Southeast Asia. The essential oil is extracted from the leaves of a tropical grass by steam distillation with a yield of around 0.2%-0.4% for West Indian lemongrass and a yield of around 0.5% for East Indian lemongrass. Citral is a major component for both types of lemongrass although East Indian lemongrass essential oil usually contains a slightly higher content of citral than West Indian lemongrass.  The grass that is left over after the distillation process is fed to the local cattle.  Traditionally, West Indian lemongrass is used in Chinese medicine to treat colds, headache, stomach ache, abdominal pain and rheumatic pain.

Did you know....
When neral and geranial are both present in an oil they are jointly known as Citral?  Citral has excellent anti-fungal properties and is known for its stimulating and insect repellent qualities.  Geranial has a strong lemon odor, while Neral's lemon odor is less intense, but sweeter. Citral is used in perfumery as an aroma compound for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. Citral is also used to mask the smell of smoke.

Lemongrass essential oil, both East Indian and West Indian, are used as the starting materials for the synthesis of ionones and Vitamin A as well as the production (isolation) of natural citral.

Lemongrass essential oil is considered by many to be stimulating yet relaxing.  It has been used from a variety of conditions including nervous exhaustion, stress, headaches, fatigue and irritability.

In her book, Aromatherapy Science, Maria Lis-Balchin, refers to a number of research studies done by herself and colleagues that showed  lemongrass oil to be strongly antispasmodic to smooth muscle of the intestine in vitro and also to uterine muscles.

Cautions:  Generally considered non-toxic,  however lemongrass is a possible dermal irritant so it should be used with care when applying topically to to skin. Avoid in pregnancy.
