1. Japan: Pickled Produce
Grill umeboshi (pickled plum) until it’s burnt, pour very hot green tea over it, then drink to reduce a fever, says Reiko Kuroda, a Japanese ex-pat living in Boston. Other home remedies for cold symptoms that she swears by: Grating lots of ginger, adding lemon and honey and dousing it with hot water, then drinking it to clear up a stuffed nose. For a sore throat, “add minced Japanese leek and minced ginger to miso paste. Pour hot water into the mixture and drink it,” she says, adding that the miso is to make it palatable rather than for therapeutic benefit.
