 Kidney Stones                              

Some diseases date back to the beginning of civilisation. Kidney or renal stones were first identified in an Egyptian mummy from about 4500 BC. It is one of the most common diseases of the urinary tract. Around two or three percent of the world's population suffers from Kidney stones. People who belong to the age group of 30 to 40 years are more prone to Kidney stones. The incidence is more in males than females.Kidney stones are usually harmless unless they start showing symptoms. Most of them are small in size and easily pass with urine.

                          Vitamin A 

Vitamin A is found only in yellow animal fats, in egg-york, milk and cheese. It is particularly plentiful in fish- liver oils, hence fish-liver oils are used for preventing and curing illness caused by lack of vitamin A. In a well-fed, healthy human being the liver can store up sufficient vitamin A to meet the body's requirements for six months.
