Many species of tea (Camellia sinensis) and cowslip (Echium amoenum) are used in Iranian traditional medicine. The aim of this study was to conduct the survey on the ability of Iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (TNF-alpha) by non-infected and infected mouse macrophages. A macrophage infection model with Legionella pneumophila and enzyme linked im...

A method of in vitro clonal propagation of cowslip Primula veris L. (Primulaceae) is reported. This is a species of medicinal importance, protected by law in Poland. MS medium Murashige and Skoog (1962) with 6 benzyladenine BA (4.44 μM) and 2,4-dichlorophenoxyacetic acid 2,4-D (1.13 μM) was found to be optimal for in vitro cowslip propagation from shoot tips under the conditions of culture. Roo...

These researches were carried out in order to introduce the species Primula officinalis into culture and establish an ecological cultivation technology.
 The Hill., synonymous with veris L., popularly known as cowslip, common cowslip or primrose, is a perennial, herbaceous species, being one of 400 genus. In some countries from Europe, this on verge extinction, due intensive harvesting spo...

The name Primula or primrose is derived from the word primary or first, referring to the early growth and flowering in spring (Liberty Hyde Bailey Hortorium, 1976). More than 400 species of primula exist in the family Primulaceae (Griffiths, 1994). Other important horticultural genera in this family, besides primula, include pimpernel (Anagallis), rock jasmine (Androsace), persian violet, alpin...
