  • Benefits of Pineapple

    Cures Sinusitis Sore Throat Gout Swellings

    Pineapples are a great source of bromelain which help prevent sinusitis. Pineapples are also effective in curing sore throat, gout and swellings. Ripe fruits perish quickly if left at room temperature and should be eaten rather early. Moreover, since they are chill sensitive and therefore, cannot be stored in the refrigerator for long periods. However, if not readily eaten; you may prepare the fruit and place the whole or cut sections wrapped inside a thin plastic cover in the refrigerator for 12 days for later use.
