Hi, I Am The Caregiver For My Mother ...and I

Hi, I am the caregiver for my mother ...and I bathe her in the am. My brother has brought a 'drug' in the house and it is being put on a clothe and placed on my mother's chest. It is haled by me and makes me 'feel light-headed'. My brother says it is 'nothing'. It has a spirit-smell, like turpentine, or mint, but very strong. My friends says it may be Colfene. What are the side effects. Thanks Jackie
