Rhubarb is also rich in vitamins and minerals that have anti-inflammatory properties and antioxidants that are cleansing and detoxifying. Rhubarb is also said to be good for those with thyroid problems.

- Rhubarb is easy to cut into pieces and freeze. Harvested rhubarb stays fresh in the refrigerator for about a week.
