Leucas aspera belongs to the phylumlaminariales. This is a group of plants that comprises the kelps and other large brown algae.




The class of an organism is a taxonomic rank, as well as a taxonomic unit, a taxon, in that particular rank used in the classification of organisms and recognized by the nomenclature codes. In biological classification, class is:
-a taxonomic rank.
-the second highest rank in the Linnaean taxonomy between order and family.
-a clade,owning to its having one or more shared derived characters (synapomorphies).




The Order of leucas aspera is Asterales, which includes asters, sunflowers, and daisies. This order is in the Euasterids I group of dicotyledons.




The plant family to which leucas aspera belongs is the Lamiaceae, which is commonly known as the mint or deadnettle family. This family contains about 7,000 species of aromatic herbs, shrubs, and trees distributed throughout the world, with the majority of species found in temperate climates. Many members of this family are used as culinary herbs, and some are used in traditional medicine. The mint family has a long history of use in folk medicine, and many mints are still used for their medicinal properties today.




Members of the genus Leucas are annual or perennial herbs, shrubs or small trees. They are found in tropical and subtropical regions of the world. The genus includes about 150 species, which are divided into two main groups: the Old World species (found in Africa, Asia and Australasia) and the New World species (found in the Americas).

The Old World species are characterised by having opposite, simple leaves and tubular or funnel-shaped flowers. The New World species have alternate, compound leaves and cylindrical flowers.

Many species in this genus are used traditionally for their medicinal properties. Some of the more well-known ones include Leucas aspera (commonly known as 'shavegrass' or 'hairy leader'), which is used to treat skin conditions such as acne and eczema; Leucas indica (commonly known as 'Indian pennywort'), which is used to treat anxiety and depression; and Leucas lavandulifolia (commonly known as 'lavender-leaved pennywort'), which is used to treat headaches.

An oil obtained from the herb has been shown to contain thymol, carvacrol, α-terpinene, p-cymene, α-terpinene, terpinen-4-ol and γ-terpinene. It also showed good antifungal activity against Trichophyton mentagrophytes. The essential oil of the herb had good spasmolytic and analgesic activity.




Leucas aspera is an important medicinal plant used in the Indian traditional system of medicine, Ayurveda. The plant is known by various names such as country mallow, Indian cotton, Indian fee gentian and wild swamp cotton. It is a small herb with white or lilac flowers and has a strong, characteristic odor. The leaves, stem and roots of the plant are used for therapeutic purposes.





The traditional uses of L. aspera are many and varied. In India, the whole plant is used to treat fever, dysentery, diarrhea, and wayside ulcers.[2][3] A decoction of the leaves is used as an antidandruff shampoo, and the fresh leaves are used as a dressing for cuts, wounds, and inflammation.[2] The leaves are also used in Tamil Nadu to treat gingivitis and stomatitis.[4][5]

In China, the herb is used to treat colds, flu, headache, dizziness, and vertigo.[6] In Nepal, it is used to treat indigestion,[7] while in Pakistan the fresh juice of the plant is used as an ear drop for treating earache.[8] In Sri Lanka, a decoction of the leaves is taken to treat snakebites[9] and various skin diseases such as eczema.[10][11] The plant is also said to have insecticidal properties,[12] and has been used in Nepal to construct beehives.[13]

L. aspera has also found application in traditional medicine elsewhere in Asia. In Vietnam, a decoction of the plant's roots is taken orally to treat coughs,[14][15] while in Burma (Myanmar), it is used as an ingredient in a liniment for treating muscle aches and pains.[16][17] The Malaysian state of Kelantan has traditionally used L. aspera leaves to prepare kompeni,[18][19] a type of dish made from combining various herbs (including L. aspera) with grated coconut.




Leucas aspera has been traditionally used in Ayurvedic and Siddha systems of medicine for the treatment of various diseases like fever, dysentery, diarrhea, asthma, bronchitis, and skin diseases. The plant is known by different tribal names such as "Tasmuli" in Meghalaya, "Tamalakki" or "Tavana kayi" in Karnataka, "Kumil" in Tamil Nadu and Kerala, "Dwidevi" or "Katuvaaruka" in Maharashtra.

The leaves are considered alterative, antiarthritic, antispasmodic, astringent, diuretic, febrifuge, refrigerant, and stimulant. A decoction of the leaves is given in fever and inflammation. The juice of the plant is taken for treating bites of poisonous insects and snakes. The paste of the root is used externally for swelling and prickly heat. The root is also chewed for treating mouth ulcers and sore throat.




The study concludes that Ethanolic and aqueous extracts of L. aspera showed significant analgesic, antipyretic and ulcerogenic activity. L. aspera can be considered a potential source of new drugs for the management of pain, fever and gastric ulcers. Further studies are warranted to elucidate the mechanism of action of the extracts.
