Centella asiatica

           Centella asiatica, commonly centella ( Sinhala : ගොටුකොල, gotu kola in Sinhala, Mandukaparni in Sanskrit मधुकपर्णी,  Sleuk tracheakkranh in Khmer ស្លឹកត្រចៀកក្រាញ់, Kannada is a small, herbaceous, annual plant of the family Mackinlayaceae or subfamily Mackinlayoideae of family Apiaceae, and is native to India, Sri Lanka, northern Australia, Indonesia, Iran, Malaysia, Melanesia, Papua New Guinea, and other parts of Asia. It is used as a medicinal herb in Ayurvedic medicine, traditional African medicine, and traditional Chinese medicine. Botanical synonyms include Hydrocotyle asiatica L. and Trisanthus cochinchinensis ( Lour. ).
          Centella asiatica grows in tropical swampy areas. The stems are slender, creeping stolons, green to reddish-green in color, connecting plants to each other. It has long-stalked, green, reniform leaves with rounded apices which have smooth texture with palmately netted veins. The leaves are borne on pericladial petioles, around 2 cm. The rootstock consists of rhizomes, growing vertically down. They are creamish in color and covered with root hairs.
          The flowers are pinkish to red in color, born in small,
rounded bunches (umbels) near the surface of the soil. Each flower is partly enclosed in two green bracts. The hermaphrodite flowers are minute in size (less than 3 mm), with 5-6 corolla lobes per flower. Each flower bears five stamens and two styles. The fruit are densely reticulate, distinguishing it from species of Hydrocotyle which have smooth, ribbed or warty fruit. The crop matures in three months, and the whole plant, including the roots, is harvested manually.
          Centella grows along ditches and in low, wet areas. In Indian and Southeast Asian centella, the plant frequently suffers from high levels of bacterial contamination, possibly from having been harvested from sewage ditches. Because the plant is aquatic, it is especially sensitive to pollutants in the water, which are easily incorporated into the plant.
          Centella is used as a leafy green in Sri Lankan cuisine, where it is called gotu kola. In Sinhalese, gotu is translated as "conical shape" and kola as "leaf". It is most often prepared as malluma (මැල්ලුම), a traditional accompaniment to rice and curry, and goes especially well with vegetarian dishes, such as dhal, and jackfruit or pumpkin curry. It is considered quite nutritious. In addition to finely chopped gotu kola, malluma almost always contains grated coconut, and may also contain finely chopped green chilis, chili powder, turmeric powder and lime (or lemon ) juice. A variation of the nutritious porridge known as kola kenda is also made with gotu kola by the Sinhalese people of Sri Lanka. Kola Kenda is made with very well-boiled red rice (with extra liquid), coconut milk and gotu kola, which is pureed. The porridge is accompanied with jaggery for sweetness. Centella leaves are also used in sweet "pennywort" drinks.
          In Indonesia, the leaves are used for sambai oi peuga-ga, an Aceh type of salad, and is also mixed into asinan in Bogor.
          In Vietnam and Thailand, this leaf is used for preparing a drink or can be eaten in raw form in salads or cold rolls. In Bangkok, vendors in the famous Chatuchak Weekend Market sell it alongside coconut, roselle, crysanthemum, orange and other health drinks.
          In Malay cuisine the leaves of this plant are used for ulam, a type of Malay salad.
          It is one of the constituents of the Indian summer drink thandaayyee.
          In Bangladeshi cuisine mashed Centella is eaten with rice and is popular for its medicinal properties.
          Centella is a mild adaptogen, is mildly antibacterial, antiviral, anti-inflammatory, antiulcerogenic, anxiolytic, nervine and vulnerary, and can act as a cerebral tonic, a circulatory stimulant, and a diuretic.
          Centella asiatica may be useful in the treatment of anxiety.
          In Thailand, tisanes of the leaves are used as an afternoon stimulant. A decoction of juice from the leaves is thought to relieve hypertension. A poultice of the leaves is also used to treat open sores.
          Richard Lucas claimed in a book published in 1966 (second edition in 1979) that a subspecies " Hydrocotyle asiatica minor " allegedly from Sri Lanka also called fo ti tieng, contained a longevity factor called 'youth Vitamin X' said to be 'a tonic for the brain and endocrine glands' and maintained that extracts of the plant help circulation and skin problems.
          Several scientific reports have documented Centella asiatica' s ability to aid wound healing which is responsible for its traditional use in leprosy. Upon treatment with Centella asiatica, maturation of the scar is stimulated by the production of type I collagen. The treatment also results in a marked decrease in inflammatory reaction and myofibroblast production.
          The isolated steroids from the plant also have been used to treat leprosy. In addition, preliminary evidence suggests that it may have nootropic effects. Centella asiatica is used to revitalize the brain and nervous system, increase attention span and concentration, and combat aging. Centella asiatica also has antioxidant properties. It works for venous insufficiency. It is used in Thailand for opium detoxification.
          http://www.ncbi.nlm.nih.gov/pubmed?term=Centella%20asiatica Many reports show the medicinal properties of C. asiatica extract in a wide range of disease conditions, such as diabetic microangiopathy, edema, venous hypertension, and venous insufficiency. The role of C. asiatica extract in the treatment of memory enhancement and other neurodegenerative disorders is also well documented. The first report concerning the antitumor property of C. asiatica extract was on its growth inhibitory effects on the development of solid and ascites tumors, which lead to increased life span of tumor-bearing rats. The authors also suggested the extract directly impeded the DNA synthesis. "In our study, C. asiatica extract showed an obvious dose dependent inhibition of cell proliferation in breast cancer cells." (From Wikipedia)
