This plant is rich in many pharmaceutical active ingredients like carotenoids, flavonoids, glycosides, steroids and sterols quinines, volatile oil, and amino acid. The extract of this plant as well as pure compound isolated from it, have been demonstrated to possess multiple pharmacological activities such as anti-cytotoxic, hepato-protective and spasmolytic amongst others. Acute toxicity studies in rats and mice suggest that the extract is relatively nontoxic. Animal tests have demonstrated minimal skin irritation, and no sensitization or photo toxicity. Minimal ocular irritation was seen with one formulation and no irritation with others. Six saponins isolated from C. officinalis flowers were not mutagenic in an Ames test, and a tea derived from C. officinalis was not genotoxic in Drosophila melanogaster. Clinical testing of cosmetic formulations containing the extract elicited little irritation or sensitization. This review has explored the organoleptic, in-vitro and in-vivo pharmacological activities as well as description, cultivation and active chemical constituents of Calendula officinalisin order to existing information on this plant as well as highlighted its multi activity properties as a medicinal agent.
