Question

Why ox liver cures night blindness and why cod liver oil and sunshine can help to cure rickets?

Answer 1

Vitamins.

Answer 2

I can't speak to the ox, but mammalian livers are rich in vitamin A, a necessary ingredient for night vision.

The ultraviolet rays in sunshine penetrate the skin for a few millimeters and lead to the body producing Vitamin D. Cod liver oil is also high in vitamin D.  Lack of vitamin D in childhood leads to an abnormal growth of the ends of the bones, a condition known as rickets.

Answer 3

Essential vitamins like Vitamin A, B6, B12, Omega 3 and Omega 6, Sunshine helps our body produce Vitamin D which in turn helps your body absorb all other nutrients and essential vitamins listed above.
