Question

Medal for best answer.....!

When the peel of colocasia is removed, it causes itching to the skin...
Why does this happen (itching the skin of the hand)..?

Answer 1

because they have Calcium oxalate crystals in their tissues . When they come in contact with sensitive part of the body such as skin , they cause itching sensation. Even in the throat it is the same effect .
\(\bigstar\)Raphides ( http://prntscr.com/3uzamm) are needle-shaped crystals of calcium carbonate or calcium oxalate found in specialized plant cells called idioblasts.
\(\bigstar\) It is believed that the raphides are a defense mechanism against plant predators, as they are likely to tear the soft tissues of the throat or esophagus of a plant predator chewing on the plant's leaves.
\(\bigstar\) It's suggested to take acidic drinks like sour curd etc as a remedy because acid dissolves the crystals.
