does calamine lotion really stop the itching of the skin?

i have very sensitive skin and it gets easily itchy and irritated when it comes near to dust or some pollen. :( i dont like scratching it because the end result does not look nice - i look like i have hives! they say that calamine lotion really works but i am a bit scared and hesitant to use it due to my wide range of allergies. have you tried calamine lotion? does it really work on healing itchy skin?
