I am planning to move to US in few days, but my uncle handed me brass plate and bowels and medicine (Paracetamol, allergy and Gastric related) with bills but preskription made by some general medicine certified guys for her wife who is living in Chicago. Since, I am going to live in Chicago and might have to stay in cousin house. It's compulsion for me to carry all there items. Are these item allowed in airplane?

Also, I am carrying only 100 dollar in cash only. Will there be any hassle over POE or anything?
