Ginger
Ginger is a muscle relaxant, or an antispasmodic which means it may have the power to stop the spasm of coughing. It also stimulates the immune system. “When you have a clear phlegm, not green or yellow, take ginger to warm up the system,” Sietos says. Slice fresh ginger into silver dollar slices and simmer it in fresh water for 20 minutes; then drink it like tea.
Add a cinnamon stick or a squeeze of lemon. “You’ll notice the cough goes away pretty quickly,” says Sietos. And if your stomach is feeling queasy, ginger can help with nausea too, according to a study in the British Journal of Anesthesia.
