Spirulina (SP) (Arthrospira platensis) is a photosynthetic, filamentous, and bluegreen microalgae that acquired its name due to the spiral or helical shape of its filaments. It contains free radical scavenging agents and naturally occurring antioxidants, including phenolic compounds, tocopherol, β-carotene, γlinolenic acid, and phycocyanin. In addition, SP and its main constituent, Cphycocyanin, exhibit hepatoprotective, neuroprotective, antiinflammatory, immune- modulatory, and anticancer action. SP has been reported to ameliorate organ toxicities induced by chemotherapeutic agents.
