If you’re prone to constipation, “an apple a day will make you go more easily, thanks to its high water and fiber content,” says Chris Kilham, founder of Medicine Hunter, Inc., and author of Tales From the Medicine Trail: Tracking Down the Health Secrets of Shamans, Herbalists, Mystics, Yogis and Other Healers. Peaches, pears, dried figs, and prunes also work as natural laxatives.
Dose: One or more apples daily.
Numerous studies show that ginger reduces nausea and morning sickness. The spicy root’s antispasmodic effects also ease an upset stomach.
Dose: Take a 500-milligram capsule two to three times a day, as needed. Or try crystallized ginger chews, or sip ginger tea. However, dried ginger works best for nausea and vomiting.
Check the Label: If you’re pregnant, don’t take any product that lists “ginger extract,” a concentrated form of ginger that can be unsafe during pregnancy.
If you suffer from irritable bowel syndrome or chronic stomach pain, taking peppermint oil before a meal can reduce intestinal cramping and bloating better than a placebo, according to a British Medical Journal study.

Peppermint tea can help with general stomach upset, but if you suffer from heartburn, be cautious: Peppermint can cause flare-ups.

The tart berry contains antioxidants that can help you recover from a urinary tract infection (UTI) faster. Although the antioxidants don’t kill the UTI-causing bacteria, they make it difficult for the bacteria to cling to the wall of the urinary tract, so they can be expelled when you urinate.
