Protective effect of Acorus calamus extract in Alcl3 induced toxicity

ACORUS CALAMUS:Sweet flag is a herbaceous perennial, 30¿100 cm (12¿39 in) tall. In habit it resembles the iris, and has given its name to the flag iris. It consists of tufts of basal leaves that rise from a spreading rhizome. The leaves are erect yellowish-green, radical, with pink sheathing at their bases, sword-shaped, flat and narrow, tapering into a long, acute point, and have parallel veins. The leaves have smooth edges, which can be wavy or crimped. The sweet flag can easily be distinguished from iris and other similar plants by the crimped edges of the leaves, the fragant odour it emits when crushed, and the presence of a spadix. Only plants that grow in water bear flowers. The solid, triangular flower-stems rise from the axils of the outer leaves. A semi-erect spadix emerges from one side of the flower stem. The spadix is solid, cylindrical, tapers at each end, and is 5 to 10 cm in length. A covering spathe, as is usual with Acoraceae, is absent. The spadix is densely crowded with tiny greenish-yellow flowers. Each flower contains six petals and stamens enclosed in a perianth with six divisions, surrounding a three-celled, oblong ovary with a sessile stigma.
