Citrus fruits are warm climate fruits containing almost all juice. They seem to be available nearly year-round in such hot states as Florida, Texas, and California, but most citrus fruits are harvested mainly in late spring to early summer, with certain types (such as navel oranges) giving a winter crop. 

Citrus fruits are known for their vitamin C content. An average orange, for example, contains about 65 mg (about the recommended daily allowance) of this important vitamin. Citruses are also high in potassium and other minerals. Like most other fruits they are low in salt (sodium). 

Citrus fruits are used commonly for cleansing the body, as during colds and flus, and for cooling it down in the summertime. Citrus juice seems to help cut grease on the hands or dishes, and it likely has the same effect on the body, helping for digestion and utilization. Citrus and vitamin C are thought to help reduce cholesterol. Gallbladder and liver function is thought to be supported by citrus fruits, especially lemons and lemon water may help stimulate digestion juice secretion. More research is needed to evaluate the actions and effect of citrus juices in the body.
