Ginger is available in three forms, namely fresh root ginger, preserved ginger and dried ginger. The pharmacological activities of ginger were mainly attributed to its active phytocompounds 6-gingerol, 6-shogaol, zingerone beside other phenolics and flavonoids. Gingerol and shogaol in particular, is known to have anti-oxidant and anti-inflammatory properties.
