Lemon Grass Oil, used as a pesticide and preservative, is put on the ancient [[palm-leaf manuscripts]] found in India as a preservative. It is used at the [[Oriental Research Institute Mysore]], the [[French Institute of Pondicherry]], Association for the Preservation of the Saint Thomas Christian Heritage in Kerala and many other manuscript collections in India. The lemon grass oil also injects natural fluidity into the brittle palm leaves and the [[hydrophobic]] nature of the oil keeps the manuscripts dry so that the text is not lost to decay due to humidity. |

Cymbopogon (lemongrass) is a genus of about 55 species of grasses, native to warm temperate and tropical regions of the Old World and Oceania. It is a tall perennial grass. Common names include lemon grass, lemongrass, barbed wire grass, silky heads, citronella grass, fever grass or Hierba Luisa amongst many others.
Uses
Lemon grass is native to India. It is widely used as a herb in Asian cuisine. It has a citrus flavor and can be dried and powdered, or used fresh.
Lemon grass is commonly used in teas, soups, and curries. It is also suitable for poultry, fish, and seafood. It is often used as a tea in African and Latin American countries (e.g., Togo, Mexico, DR Congo).
Research also shows that lemon grass oil has anti-fungal properties.[1]
Citronella Grass (Cymbopogon nardus and Cymbopogon winterianus) is similar to the species above but grows to 2 m and has red base stems. These species are used for the production of citronella oil, which is used in soaps, as an insect repellent in insect sprays and candles, and also in aromatherapy, which is famous in Bintan, Indonesia. The principal chemical constituents of citronella, geraniol and citronellol, are antiseptics, hence their use in household disinfectants and soaps. Besides oil production, citronella grass is also used for culinary purposes, in tea and as a flavoring.
Lemon Grass Oil, used as a pesticide and preservative, is put on the ancient palm-leaf manuscripts found in India as a preservative. It is used at the Oriental Research Institute Mysore, the French Institute of Pondicherry, the Association for the Preservation of the Saint Thomas Christian Heritage in Kerala and many other manuscript collections in India. The lemon grass oil also injects natural fluidity into the brittle palm leaves and the hydrophobic nature of the oil keeps the manuscripts dry so that the text is not lost to decay due to humidity.
East-Indian Lemon Grass (Cymbopogon flexuosus), also called Cochin Grass or Malabar Grass (Malayalam: ഇഞ്ചിപ്പുല്ല്ല്ല്(inchippull), is native to Cambodia, India, Sri Lanka, Burma,and Thailand while the West-Indian lemon grass (Cymbopogon citratus), also known as serai in Malay, is assumed to have its origins in Malaysia. Indonesian people used to called it serai too or sereh. While both can be used interchangeably, C. citratus is more suited for cooking. In India C. citratus is used both as a medical herb and in perfumes. Cymbopogon citratus is consumed as a tea for anxiety in Brazilian folk medicine,[2] but a study in humans found no effect.[3] The tea caused a recurrence of contact dermatitis in one case.[4]
Lemon grass is also known as "Gavati Chaha" in the Marathi language(Gavat-grass; chaha-tea), and is used as an addition to tea,and in preparations like 'kadha' which is a traditional herbal 'soup' against cough,cold etc. It has medicinal properties and is used extensively in ancient Indian Ayurvedic medicines. It is supposed to help with relieving cough and nasal congestion.
Anti-cancer properties
In 2006 a research team from the Ben Gurion University in Israel found that Lemon grass (cymbopogon citratus) caused apoptosis (programmed cell death) in malignant cancer cells. According to the research team citral is the substance that causes the cancer cells to kill themselves. The influence of citral on normal cells and malignant cancer cells that were grown on a petri dish. The quantity added in the concentrate was equivalent to the amount in a cup of regular tea using one gram of lemon grass in hot water. While the citral killed the cancer cells, it left the normal cells unharmed. This selective toxicity amazed the researchers.[5]
