Mechanism of Action

Pharmacology:

  • Constituents: The "pungent principles" or nonvolatile constituents of ginger are considered responsible for its flavor, aromatic properties, and pharmacological activity. These include: gingerols including (6)-gingerol (usually <1% of the root's weight)22, (6)-shagaol (a dehyroxylated analog of (6)-gingerol), (6)- and (10)-dehyro-gingerdione, (6)- and (10)-gingerdione, (6)-paradol, vallinoids, galanals A and B, and zingerone. Other compounds present include carbohydrates, fats, minerals, oleoresins, vitamins, waxes, and zingibain (a proteolytic enzyme). The rhizome of ginger contains pungent vanillyl ketones, including (6)-gingerol and (6)-paradol, and has been reported to possess strong anti-inflammatory activity as well as anti-tumor promoting properties.23
  • Anti-cancer effects: The anticancer effects of ginger are thought to be attributed to various constituents including vallinoids, viz. (6)-gingerol and (6)-paradol, shogaols, zingerone, and galanals A and B.18,17,24 Galanals A and B have been found to be potent apoptosis inducers of human T lymphoma Jurkat cells.17
  • Anticoagulant effects: Ginger has been shown to inhibit platelet aggregation1,2,10 and to decrease platelet thromboxane production in vitro25,26,10. (8)-Gingerol, (8)-shogaol, (8)-paradol, and gingerol analogues (1 and 5) exhibited anti-platelet activities.10 However, its effects in vivo have not been well studied. Although Verma et al. found ginger to decrease platelet aggregation27, Lumb found no effect of ginger on platelet count, bleeding time, or platelet aggregation28. Similarly, Bordia et al. found ginger to have no effect on platelet aggregation, fibrinolytic activity, or fibrinogen levels.29 Janssen et al. showed no effect of oral ginger on platelet thromboxane B2 production30, while Srivastava found thromboxane levels to be decreased by ginger ingestion in a small study31.
  • Antiemetic effects: The mechanism of action of ginger's effect on nausea and vomiting remains uncertain. However, there are several proposed mechanisms. The components in ginger that are responsible for the antiemetic effect are thought to be the gingerols, shogaols, and galanolactone, a diterpenoid of ginger.32,33,34 Recent animal models and in vitro studies have demonstrated that ginger extract possesses antiserotoninergic and 5-HT3 receptor antagonism effects, which play an important role in the etiology of post-operative nausea and vomiting.35,34,36,6,33,6 In a randomized, placebo-controlled, crossover trial of 16 healthy volunteers, ginger (1g orally) had no effect on gastric emptying.37 It appears unlikely that ginger's anti-emetic or anti-nausea effects are mediated through increased gastroduodenal motility or through increased gastric emptying. Using gastroduodenal manometry, Micklefield et al. demonstrated that oral ginger increases antral motility during phase III of the migrating motor complex (MMC) and increases motor response to a test meal in the corpus.38 However, ginger had no significant effect in the antrum or corpus during other phases, except for a significant decrease in the amplitude of antral contractions during phase II of the MMC. Additionally, there was no effect of ginger on duodenal contractions or on the "motility index."
  • Anti-inflammatory effects: Ginger has a long history of use as an anti-inflammatory and many of its constituents have been identified as having anti-inflammatory properties.3 Ginger has been found to inhibit prostaglandin biosynthesis16 and interfere with the inflammatory cascade and the vanilloid nociceptor9. Ginger has been shown to share pharmacological properties with non-steroidal anti-inflammatory drugs (NSAIDs) because it suppresses prostaglandin synthesis through the inhibition of cyclooxygenase-1 and cyclooxygenase-2. However, ginger can be distinguished from NSAIDs based on its ability to suppress leukotriene biosynthesis by inhibiting 5-lipoxygenase. This discovery preceded the observation that dual inhibitors of cyclooxygenase and 5-lipoxygenase may have a better therapeutic profile and have fewer side effects than NSAIDs. It was also discovered that a ginger extract (EV.EXT.77) derived from Zingiber officinale (and Alpina galanga) inhibits the induction of several genes involved in the inflammatory response, including genes encoding cytokines, chemokines, and the inducible enzyme cyclooxygenase-2. This discovery provided the first evidence that ginger modulates biochemical pathways activated in chronic inflammation. Identification of the molecular targets of individual ginger constituents provides an opportunity to optimize and standardize ginger products with respect to their effects on specific biomarkers of inflammation.
  • Antinociceptive effects: (6)-shogaol has produced anti-nociception and inhibited the release of substance P in rats, seemingly via the same receptor to which capsaicin binds. However, it was observed to be 100 times less potent and to elicit half the maximal effect of capsaicin.39
  • Antioxidant effects: In vitro, ginger has been shown to exhibit antioxidant effects.9 (6)-gingerol appears to be the antioxidant constituent present in ginger, as it was shown to protect HL-60 cells from oxidative stress.4 Ginger oil has dominative protective effects on DNA damage induced by H2O2. Ginger oil might act as a scavenger of oxygen radical and might be used as an antioxidant.21
  • Antitussive effects: (6)-shogaol, generally more potent than (6)-gingerol, has exhibited antitussive effects.19
  • Cardiovascular effects: In vitro research indicates that gingerols and the related shogaols exhibit cardiodepressant activity at low doses and cardiotonic properties at higher doses.7 Both (6)-shogaol and (6)-gingerol, and the gingerdiones, are reportedly potent enzymatic inhibitors of prostaglandin, thromboxane, and leukotriene biosynthesis.
  • Gastrointestinal effects: There is evidence that ginger rhizome (root) increases stomach acid production. If so, it may interfere with antacids, sucralfate (Carafate®), H2 antagonists, or proton pump inhibitors. In contrast, other in vitro and animal studies have revealed gastroprotective properties.14,15 In addition, (6) shogaol, generally more potent than (6)-gingerol, has inhibited intestinal motility in intravenous preparations and facilitated gastrointestinal motility in oral preparations. Ginger extract has also been reported to inhibit the growth of Helicobacter pylori in vitro.5 However, Desai et al. observed a significant increase in the exfoliation of gastric surface epithelial cells following the consumption of 6g or more of ginger (after examining gastric aspirates in 10 healthy volunteers).20
  • Immunomodulatory effects: The authors of one systematic review concluded that in vitro evidence indicates that ginger has immunomodulatory effects and is an effective antimicrobial and antiviral agent.9
  • Lipid effects: Oral ingestion of ginger extract has been shown to have hypocholesterolemic, hypolipidemic, and antiatherosclerotic effects in cholesterol-fed rabbits11 and in rats13. Inhibition of LDL oxidation and attenuated development of atherosclerosis has also been observed in apolipoprotein E-deficient mice.12
  • Weight loss effects: Spiced foods or herbal drinks, such as those that contain ginger, have the potential to produce significant effects on metabolic targets, such as satiety, thermogenesis, and fat oxidation.8 A significant clinical outcome sometimes may appear straightforwardly but also depends too strongly on full compliance of subjects. Thermogenic ingredients, such as ginger, may be considered as functional agents that could help restore a "positive energy balance" and prevent obesity.

Pharmacodynamics/Kinetics:

  • Insufficient available evidence.
