When the leaves are crushed, they release a refreshing fragrance that closely resembles the scent of lemon, which is why it is widely used in cooking and herbal remedies.

The essential oil extracted from lemon grass is a yellow or amber liquid known for its antiseptic properties. This oil can be effectively used to treat conditions such as athlete's foot (tinea pedis). In addition to its medicinal uses, the stem and leaves of lemon grass are commonly utilized as a spice in Asian cuisine, adding a unique flavor to dishes such as soups, curries, and stir-fries.

Furthermore, lemon grass serves multiple purposes beyond culinary applications. It is often employed as an insect repellent due to its strong aroma, which is unappealing to many pests. Additionally, it acts as a carminative, helping to alleviate digestive issues. In the cosmetic industry, products containing Cymbopogon citratus are increasingly popular, particularly in soaps and hair care formulations, where its refreshing scent and beneficial properties are highly valued.

Lemon grass is not only a flavorful addition to meals but also possesses several therapeutic benefits. It is commonly used as a natural remedy for a variety of ailments, including coughs, cuts, asthma, and bladder disorders. Its diaphoretic properties make it effective for promoting sweating, which can help in detoxification. Moreover, lemon grass is known to provide relief from headaches, making it a versatile herb in both culinary and medicinal applications.
