Infections caused by Salmonella and other pathogens According to a 2009 research published in the Internet Journal of Third World Medicine by T.E. Ayogu, PhD, ethanol-based ginger extract kills salmonella typhi bacteria. However, this study also notes that further research is needed to determine the effects of ginger extract on other pathogenic microorganisms. Ginger has many health benefits for people who eat it regularly. It can help prevent or treat nausea when you are taking chemotherapy drugs. Ginger may also be able to help reduce fever, pain, and inflammation from arthritis or other conditions. Last but not least, eating ginger can help control gastric reflux disease (GRD). People with GRD suffer from acid reflux into their esophagus from the stomach. This problem can cause heartburn symptoms such as chest pain, regurgitation, vomiting, and indigestion. Eating spicy foods like chili peppers, coffee, alcohol, and citrus fruits can irritate the stomach lining and cause more acid to come up from the stomach. These substances must be avoided while trying to control GRD with ginger because they will only exacerbate the problem. Those who are sick or have a weak immune system should avoid eating spicy foods if they are trying to control their salmonella infection.
