The pomelo is said to cure hangovers. In Malasia and Filipines, a lotion made from the pomelo plants leaves is used to alleviate sores and swellings. The Filipinos also use it as a sedative for nerves. The Chinese use the entire plant to make medications that cure coughs, car sickness and indigestion. A paste of pomelo rind and ginger can be applied to joints to ease arthritic pain.
