Talinum triangulareleaf ginsengTalinum triangularefoliageThe origin of the name Talinum is obscure; triangulare refers to the sharply triangular flowering axes.

The plant is found growing wild in many tropical regions of the world, and its origin is uncertain, but it may well have originated in South America, It is a fast-growing perennial herb to 60 cm high or a little more, with a spread of up to about 50 cm, and has a soft main stem and branches. The leaves are oblanceolate in shape, a lush green in colour, and slightly fleshy, up to about 8 cm long. The star-like flowers are pink, about 2 cm in diameter, with 5 petals. Globular fruit capsules are produced, about 5 mm in diameter, that are explosively dehiscent, and scatter the tiny black seeds over quite an area. In the tropics, it is best grown in a fairly shady position, but in cooler climates it should have some sun. In cold climates it is probably best grown in a pot, so that it can be shifted under shelter in the winter. It thrives in humid conditions, in temperatures around 30 ºC, in rich, fairly acidic, well-drained soil under partial shade, and is much cultivated along the banks of the Amazon River.

The plant will normally reproduce from the seeds it scatters, but it may also be grown from stem cuttings. It is quite resistant to pests and diseases, but snails are very partial to it: indeed, in some places it is used a fodder for the raising of edible snails.

Leaf Ginseng is used as a leaf vegetable, especially in many third world countries. It is commercially cultivated in Nigeria, Cameroon, the Caribbean, Brazil and the Philippines. Its fleshy leaves and stems make for good water storage, and so it will thrive in countries with high temperatures and intermittent rainfall patterns.  When cut and stored, the tops of the plants will remain fresh and crunchy for quite a long period, even without refrigeration.

As the plant contains oxalic acid, it is not safe to eat too much of it in the green state, Although blanching and cooking reduce the risks associated with the acid, caution is advised when feeding the plant to infants, or to people who suffer from kidney stones, gout or rheumatoid arthritis.

Increasing use is being made of the plant for medicinal purposes, and various studies are being made into its therapeutic effects, especially in Nigeria. It is claimed to be effective in such areas as gastrointestinal disorders, diarrhœa, peptic ulcers, dysentery, hepatic ailments, measles, oedema, anaemia and high blood pressure. It is also used externally, its crushed leaves being applied to swellings, inflammations and sores. A veritable panacea!
