The previous studies revealed that Equisetum arvense contained alkaloids, carbohydrate, proteins and amino acids, phytosterols, saponins, sterols, ascorbic acid, silicic phenol, tannin, flavonoids, triterpenoids, volatile oils many other biological active constituents. E. has been used as a folklore medicine for treatment of various conditions such tuberculosis, catarrh in the kidney bladder re...

Equisetum arvense, commonly known as the field horsetail, has potential as a new functional food ingredient. However, little information is available on its side effects, and the general toxicity of Equisetum arvense has yet to be examined in detail. In the present study, we evaluated the influence of administration in diet at doses of 0, 0.3, 1 and 3% for 13 weeks in male and female F344 rats....

BACKGROUND AND AIMS Only few data on the epicuticular waxes (EWs) of horsetails are available. This contribution therefore focuses on the wax micromorphology and chemical composition of Equisetum species of the subgenera Equisetum and Hippochaete. METHODOLOGY Distribution patterns and structural details of EW on the shoots were studied by scanning electron microscopy. After extraction with ch...

The greater Equisetum arvense is an herbaceous plant from the family Equisetaceae commonly found in North America, Europe and Asia. has been used since ancient times medical practice because of its pharmacological applications, presence many biologically active compounds, including flavonoids, alkaloids, carbohydrate, proteins amino acids, phytosterols, saponins sterols. Scientific data reveals...

Equisetum is described for the first time from Cenozoic deposits of New Zealand. The fossils derive from two early to earliest middle Miocene assemblages in South Island, New Zealand. The fossils are ascribed tentatively to subgenus Equisetum based on their possession of whorled branch scars, but they cannot be assigned with confidence to a formal species. The decline of equisetaleans, otherwis...
