Scientifically known as Cymbopogon khasans, jamrosa refers to a grass hybrid, which is generally of a pale yellowish color. The origin of jamrosa grass is in India and it is widely grown in areas like Chhattisgarh, Maharashtra, Madhya Pradesh and also in the southern parts of the country. The jamrosa oil is extracted from the highly aromatic jamrosa grass. This medium sized grass is of hybrid origin, being a cross between the palmarosa and citronella. It is a plant which generally grows in the wild. The high quantities of ocimene and geraniol present in jamrosa imparts it with the scents of mangoes and roses and this is how it differs from the palmarosa. Recently, the jamrosa products have seen a rise in demand and commercial cultivation of the grass on a larger scale is required. The Regional Research Laboratory (RRL) in Jammu has developed a new variety of the jamrosa which is called CN-5.


The strong fibers of the jamrosa are also used to make idols and statues containing plaster of Paris. This grass provides highly useful products and is greatly favored by the industry. Its long and strong fibers are useful in the making of ropes. Jamrosa supplies the raw materials for industries based on fiber. Traditionally, jamrosa has been used as a perfumery compound as it possesses the scent of roses. Geraniol & Geranyl Acetate are two useful products derived from the jamrosa oil. The spent grass of jamrosa is used in the making of cattle feed and organic manure. Handmade papers are also made from jamrosa products and also for making dhoop, agarbatti/ masala agarbatti and raw agarbatti. The spent water of the plant is used to make natural insect repellent. The spent water of the

plant is highly pure in quality and has many chemical agents which can be dissolved easily in water. It is considered good for health reasons. Jamrosa is also used for creating fragrances like rose fragrances. These grasses are ecologically important as they have the ability to prevent soil erosion, recharge the ground water and to detoxify environmental contamination.

A tough and hardy plant, it flourishes in many types of soils. Generally, it grows best in loamy sands having PH levels ranging from 6.5 to 8.5. It grows well in a warm and humid climate accompanied by adequate sunshine and annual rainfall of at least 800 mm. Given the right conditions, it grows vigorously. Jamrosa is propagated through slips produced after the splitting of the well grown clumps. Within a year, a mature clump can produce as many as 60 slips. Each slip is placed at a spacing of 40 x 40cm. One hectare can have as many as 62,500 slips. The land should be ploughed at least thrice and weeds should be removed. The beds should be properly leveled and provided with adequate irrigation. In India, the land is dependent on rains for water and for the drier lands, planting of the highly

fragrant aromatic grasses and plants is recommended. Cymbopogon family are ideal for this purpose. The production of Jamrosa oil is subject to the climatic conditions. In summer, the amount of Jamrosa oil derived from the grass is greater than during the rainy season. CN-5, a variety of jamrosa can be easily cultivated even in the dry areas and thus, it is commercially more viable. It does not require much rain and thus, is largely immune to the vagaries of nature, creating no possibility of loss. Aromatic grasses grow throughout the year, and require less manpower. They are a ready source of income to farmers and those who live near forests. Saplings are best used in the cultivation of jamrosa. No seeds are required to produce this and it is relatively easy to grow.

Jamrosa Oil
Jamrosa oil is extracted through the process of steam distillation. The oil is composed of 75% geraniol and 20% geranyl acetate. The scent of jamrosa can be described as a rose-grassy scent but it is less stronger than that of the palmarosa. Jamrosa blends well with palmarosa, geranium, rose geranium, ginger grass and juniper berry. It is an antiseptic, bactericidal, digestive stimulant and febrifuge.The jamrosa oils are used in the food and flavoring industries. These oils are replete with valuable medicinal properties and other health giving properties.
