The basal portions of the leafy shoots have a delicious lemon-like aroma and are used as a flavouring in soups, sauces and curries[ 301 , K ].

It can be served hot or cold[ 301 ]. It can be sweetened with sugar[ 521 ]. The essential oil is used as a flavouring in the food industry in soft drinks and various foods[ 238 , 418 ].
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.



Lemongrass was one of the herbs that was transported along the spice route from Asia to Europe. Lemon grass is a bitter, aromatic, cooling herb that increases perspiration and relieves spasms[ 238 ]. The essential oil obtained from the plant is an effective antifungal and antibacterial[ 238 ]. The essential oil contains about 70% citral, plus citronellal - both of these are markedly sedative[ 254 ]. Internally, the plant is used principally as a tea in the treatment of digestive problems, where it relaxes the muscles of the stomach and gut, relieving cramping pains and flatulence[ 254 ]. It is particularly useful for children, for whom it is also used to treat minor feverish illnesses[ 238 , 254 ]. Externally, especially in the form of the extracted essential oil, the plant is a very effective treatment for a range of conditions including athlete's foot, ringworm, lice and scabies[ 238 ]. It is also applied to ease the pain of arthritic joints[ 254 ].

 

Other Uses
Landscape Uses: Border, Container, Erosion control, Ground cover, Massing, Specimen. Agroforestry Uses: A good soil conditioner in worn out land. The plants quickly produce a bulk of organic material which soon rots down, attracting worms and other beneficial creatures and quickly enriching the soil[ 296 ]. A row of lemongrass plants can be used as a divider in the garden - it can help to contain more invasive plants such as sweet potato, and also as a barrier to prevent weeds growing into the garden[ 296 ]. The grass is useful for soil improvement and erosion control[ 418 ].. Other Uses An essential oil obtained from the plant is used in perfumery, scenting soaps, hair oils, cosmetics and as an insect repellent[ 238 , 254 , 418 ]. It is also used in the synthesis of vitamin A[ 418 ]. It is cytotoxic, which could be exploited for pesticidal or chemotherapeutic agents. It has insecticidal, larvicidal, nematicidal, pro-oxidative, repellent activity and is a vasorelaxant.
Cultivation details
A plant of the tropics and subtropics, where it is found at elevations up to 1,400 metres. It grows best in areas where annual daytime temperatures are within the range 24 - 30c, but can tolerate 18 - 34c[ 418 ]. It can be killed by temperatures of 10?c or lower[ 418 ]. It prefers a mean annual rainfall in the range 1,500 - 3,000mm, but tolerates 700 - 4,200mm[ 418 ]. Prefers a moisture-retentive soil in full sun[ 200 ]. Prefers a pH in the range 5 - 5.8, tolerating 4.3 - 7.3[ 418 ]. Harvesting begins when the crop is 120 - 240 days old, and the plant is subsequently harvested every 90 - 120 days[ 418 ]. The plant has an economical life of 4 years[ 418 ]. Fresh grass yields 0.2 - 0.4% oil, with an average yield of 50 - 120 kilos of oil/ha per annum. Yield of foliage is higher on fertile heavy soils, but under these conditions the oil usually has a lower citral content[ 418 ] The plant seldom flowers[ 418 ]. Lemongrass should be stored separately from other foods, or should be well wrapped, otherwise its strong scent will taint the other foods[ 200 ].
