Pharmacology of Ginger
Ginger and 6-gingerol have strong antioxidant action both in vivo and in vitro, in addition to strong anti-inflammatory and anti-apoptotic actions
The antioxidant action of ginger has been proposed as one of the major possible mechanisms for the protective actions of the extract against toxicity and lethality of radiation (Jagetia et al., 2003; Haksar et al., 2006), and a number of toxic agents such as carbon tetrachloride and cisplatin (Amin and Hamza, 2006; Yemitan and Izegbu, 2006), and as an anti-ulcer drug (Siddaraju and Dharmesh, 2007).
Recently, it has been shown that 6-gingerol has strong antioxidant action both in vivo and in vitro, in addition to strong anti-inflammatory and anti-apoptotic actions (Kim et al., 2007). This makes it a very effective agent for prevention of ultra violet B (UVB)-induced reactive oxygen species (ROS) production and COX-2 expression, and a possible therapeutic agent against UVB-induced skin disorders.
