Sinus-clearing ginger root is famous for its immunity boosting powers as well as its ability to cleanse the palate and add zing to dense cakes or sauces. Prized by ancient Indian and Chinese cultures, it was used as early as 5,000 years ago as a cure for common ailments like stomach pain. Those early ancestors were onto something, as anyone who’s sipped ginger tea can attest to. The powdered version is a great way to heat up classic American fall dishes, such as pumpkin and apple pie.
