DigestZen and Ginger together in a carrier oil and rub on stomach and back. Basil diluted in carrier oil and rubbed on the bottom of feet. Inhaling peppermint (a very small amount, on a cotton ball, also combats nausea).
DigestZen works wonderfully to calm an upset stomach. I have heard a couple people attest to this, lately. Ginger has long been used to help with nausea and throwing-up, as well as peppermint. Basil is helpful for gastric spasms, is useful for infections and is calming. Some use it diluted and massage it right onto the abdomen.
