Centella asiatica, commonly known as Gotu kola, kodavan, Indian pennywort and Asiatic pennywort, is a herbaceous, perennial plant in the flowering plant family Apiaceae. It is native to the wetlands in Asia. It is used as a culinary vegetable and as a medicinal herb.
Centella grows in temperate and tropical swampy areas in many regions of the world. The stems are slender, creeping stolons, green to reddish-green in color, connecting plants to each other. It has long-stalked, green, rounded apices which have smooth texture with palmately netted veins. The leaves are borne on pericladial petioles,[clarification needed] around 2 cm (0.79 in). The rootstock consists of rhizomes, growing vertically down. They are creamish in color and covered with root hairs.
The flowers are white or crimson 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 (0.12 in), with five to six 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. It is a highly invasive plant, rated as "high risk". Centella has numerous common names in its regions of distribution.
Centella asiatica is indigenous to the Indian subcontinent, Southeast Asia, and wetland regions of the Southeastern US. Because the plant is aquatic, it is especially sensitive to biological and chemical pollutants in the water, which may be absorbed into the plant. It can be cultivated in drier soils as long as they are watered regularly enough (such as in a home garden arrangement).
Centella contains pentacyclic triterpenoids, including asiaticoside, brahmoside, asiatic acid, and brahmic acid (madecassic acid). Other constituents include centellose, centelloside, and madecassoside.
In Burmese cuisine, raw pennywort is used as the main constituent in a salad mixed with onions, crushed peanuts, bean powder and seasoned with lime juice and fish sauce. Centella is used as a leafy green in Sri Lankan cuisine, being the predominantly locally available leafy green, where it is called gotu kola. It is most often prepared as malluma, a traditional accompaniment to rice and vegetarian dishes, such as dal, and jackfruit or pumpkin curry. It is considered nutritious. In addition to finely chopped gotu kola plants, the gotu kola malluma may be eaten with grated coconut, diced shallots, lime (or lemon) juice, and sea salt. Additional ingredients are finely chopped green chilis, chili powder, turmeric powder, or chopped carrots. The Centella fruit-bearing structures are discarded from the gotu kola malluma due to their intense bitter taste. A variation of porridge known as kola kenda is also made with gotu kola in Sri Lanka. Gotu kola kenda is made with well-boiled red rice with some extra liquid, coconut milk first extract, and gotu kola purée. The porridge is accompanied with jaggery for sweetness. Centella leaves are also used in modern sweet pennywort drinks and herbal teas. In addition the leaves are served stir-fried whole in coconut oil, or cooked in coconut milk with garlic or dhal.
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 Cambodia, 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 Chatuchak Weekend Market sell it alongside coconut, roselle, chrysanthemum, orange and other health drinks. In Malay cuisine it is known as pegaga, and the leaves of this plant are used for ulam, a type of vegetable salad. C. asiatica is widely used in various Indian regional cuisines. In Bangladesh Centella is called Thankuni Pata and used in various dishes, one of the most appetising of which is the pakora-like snack called Thankuni Patar Bora; made of mashed Centella, lentils, julienne-ed onion and green chilli.
In traditional medicine, C. asiatica has been used to treat various disorders and minor wounds, although clinical efficacy and safety have not been scientifically confirmed. Contact dermatitis and skin irritation can result from topical application. Drowsiness may occur after consuming it. The herb may have adverse effects on liver function when used over many months.
In the context of phytoremediation, C. asiatica is a potential phytoextraction tool owing to its ability to take up and translocate metals from root to shoot when grown in soils contaminated by heavy metals.
Note that wherever the number of seeds is indicated in grams, there may be more or fewer seeds in the package because the seeds are not the same size and weight.
If indicated in grams, the number of seeds loses relevance and is only there to show the approximate number of seeds in the package.
For example "Price for pack of 50 (1g) seeds." so you are not buying the number of seeds but the weight.
