Chemical Constituents and Components :Main chemical constituents are asarone, alpha pinene, beta asarone, calamenol, calamene, calamenone, eugenol, methyl eugenol, calamone, azulene, sugars, glucosides, and flavones.

Action :
Glycosides:
1. It increases the glutathione (GSH) content and glutathione-S-transferase GST activity in the corpus striatum.
2. It inhibits free radical scavengers and lipid peroxidation.
3. It inhibits the mitogen and antigen-stimulated human peripheral blood mononuclear cells thus potentially suppress the immune system.
4. It stimulates sodium/potassium pump activity. Saponins:
1. It causes calcium channel blockage due to which it causes the potent spasmolytic effect.
2. It promotes the reduction of lipid concentrations in the serum.
Curing Diseases:1. It is useful in flatulence, colic, dyspepsia, dysentery, stomach problems and worm affection.

Research Information:C rude methanolic extract of Acorus calamus rhizomes possesses antimicrobial activity against bacteria, fungi and yeast. It shows a strong effect against filamentous fungi like Trichophytum rubrum and Microsporum gypseum, moderate inhibitory effect against yeast and low against bacteria. (Ref.
