Received: 31 December 2016 Accepted: 31 January 2017 Published: 05 February 2017 Abstract: The preliminary phytochemical analysis of Eryngium creticum showed that it contained alkaloids, tannins, resins, saponins, coumarin, phenols, terpenoids, flavonoids and carbohydrates. The previous pharmacological studies revealed that Eryngium creticum possessed antioxidant, antimicrobial, anti-inflammatory, antinociceptive, anticancer, antileishmanial and many other effects. The current review highlights the chemical constituents, pharmacological and therapeutic effects of Eryngium creticum. Keywords: Eryngium creticum, constituents, pharmacology, therapeutic.

It is getting popularized in developing and developed countries Traditional uses: owing to its natural origin and lesser side effects. Plants It was cultivated for the consumption as a leafy are a valuable source of a wide range of secondary vegetable in salads. It was used medicinally as a metabolites, which are used as pharmaceuticals, diuretic and laxative. Roots and seeds were immersed agrochemicals, flavours, fragrances, colours, in water are drunk by people to treat kidney stones, biopesticides and food additives [1-16]. The preliminary infections, skin diseases, and tumors as antidote for the phytochemical analysis of Eryngium creticum showed treatment of the snakebite. It was also used for the that it contained alkaloids, tannins, resins, saponins, treatment of liver diseases, poisoning, anemia and coumarin, phenols, terpenoids, flavonoids and infertility [22-23]. carbohydrates.
