It is from Watkins it is Petro-Carbo active ingredient Phenol [Carbolic Acid]. http://www.watkinsonline.com/peper/ My mom always made lemon cake and she got the pure lemon extract for the cake. She also got vanilla extract and made snow cream. It was always the second snow fall because the first snow fall was polluted and she got it on a car or shed. She said she did not want to go where an animal had been. My mom also made lemon cookies, they were my favorite plus I loved watching Tabbie dunking a cookie in her water bowl because the cookie melted. Tabbie was our pet raccoon and she looked every where for her cookie. Her mom got shot and my dad brought her home. Tabbie was about the size of an adults hand. My mom would start to sew and Tabbie would get in the sewing and make mom stop to pet her.
