Why do Euphorbiaceae tick as medicinal plants? A review of Euphorbiaceae family and its medicinal features

Euphorbiaceae is among the large flowering plant families consisting of a wide variety of vegetative forms some of which are plants of great importance. Its classification and chemistry have of late been subjects of interest possibly because of the wide variety of chemical composition of its members, many of which are poisonous but useful. In this review, we have tried to demonstrate why Euphorbiaceae are important...

Assessment of the effect of Echinacea purpurea extract on the accumulation of cadmium in liver and kidney: Apoptotic - mitotic activity of liver cells

Cadmium (Cd) is an important industrial pollutant, even though its mechanism of toxicity has not been completely clarified. Although Cd2+ is toxic to a wide range of organs and tissues, liver and kidneys are the primary target organs of cadmium toxicity. Cd2+ induces apoptosis, mitotic activity of cells and also causes necrotic cell death in certain pathophysiological situations. Echinacea...
