While giving myself a pedicure, the shavings from scrapping my feet is green. This weekend I used alcohol on my feet it was also green. What are some of the possible causes for this? I don t drink alcohol, use drugs or take vitamins. I use 100% natural shea butter on my feet sometimes; as well as blended combination of 100% natural oils such as Jojoba, coconut, flaxseed, argan and olive on my body.
