Home remedies for nausea and upset stomach include bitters and soda, ginger, peppermint, and apple cider vinegar, according to Healthline. In addition, adhering to the "BRAT" diet, named as an acronym for its constituents of bananas, rice, applesauce and toast, helps both adults and children with upset stomachs.
Ginger has a history of treating digestive upsets that goes back thousands of years, points out Everyday Health. An anti-nausea treatment that is safe for pregnant women, it also helps people suffering from nausea due to motion sickness and chemotherapy. It can be drunk as a tea, used in cooking, or eaten in candied form.
Because the BRAT diet is extremely bland and low-fiber, it is gentle on upset digestive systems, as Healthline explains. Overtoasting the toast is particularly helpful for fighting nausea. Apple cider vinegar fights an upset stomach by neutralizing the stomach acids. Some people take apple cider vinegar daily to keep gut bacteria healthy. If the taste is too strong, one recommendation is to dilute it with honey for easier swallowing.
Peppermint is another anti-nausea home remedy that is safe for pregnant women. Drinking peppermint tea or sucking on a peppermint candy can reduce symptoms of nausea, indigestion and irritable bowel syndrome, according to Everyday Health.
