Homeopathic remedies for nausea include ingesting ginger or peppermint, using acupuncture or acupressure and employing aromatherapy with peppermint or lemon scents, according to Everyday Health. Adding ginger to foods can reduce nausea, and both ginger and peppermint can be consumed as a tea.
Peppermint increases the speed of digestion and reduces discomfort, notes Everyday Health, though experts still aren't exactly sure why ginger works. Acupuncture and acupressure have been shown to work at least as well as conventional medicines for nausea, especially when done by a trained professional. Aromatherapy works by removing scents that may be contributing to nausea and introducing ones that reduce nausea, such as ginger.
