NCCIH (National Center for Complementary and Integrative Health) May 2019 report gives fact sheet information on using fresh ginger to assist with pregnancy related symptoms of nausea and vomiting as well as arthritic inflammatory conditions. Cautions are listed for side effects of abdominal discomfort, heartburn, diarrhea and gas (temporary) as well as interactions with blood thinners. Ginger can be added to tea, used in a juicer, or added to cooked vegetables. Cooking may alter the effectiveness, requiring higher doses.
