However, some herbs and spices may offer additional health benefits. One of these is ginger.
Scientific analysis shows that ginger contains hundreds of compounds and metabolites, some of which may contribute to health and healing. Of these, the gingerols and shogaols have been most extensively researched.
The phenolic compounds in ginger are known to help relieve gastrointestinal (GI) irritation, stimulate saliva and bile production, and suppress gastric contractions as food and fluids move through the GI tract.
At the same time, ginger also appears to have beneficial effects on the enzymes trypsin and pancreatic lipase, and to increase motility through the digestive tract. This suggests ginger could help prevent colon cancer and constipation.

Ginger has also been found to reduce the symptoms of dysmenorrhea, the severe pain that some women experience during a menstrual cycle.
Ginger has been used for centuries to reduce inflammation and treat inflammatory conditions.
A study published in Cancer Prevention Research journal reported that ginger supplements, which are available to buy online, reduced the risk of colorectal cancer developing in the bowel of 20 volunteers.
Ginger has also been found to be “modestly efficacious and reasonably safe” for treating inflammation associated with osteoarthritis.
6. Cardiovascular health
Other possible uses include reducing cholesterol, lowering the risk of blood clotting, and helping to maintain healthy blood sugar levels. More research is needed, but if proven, ginger could become part of a treatment for heart disease and diabetes.
