RezBlock Concentrate is an all-natural concentrate solution that you add to the water in your clean water pipe. RezBlock will prevent resin from sticking in all areas that the mixture is touching. RezBlock is made from organic ingredients - all of which you can buy in a health food store. Fruit and vegetable extracts are used to make RezBlock along with salt which acts as a preservative and food coloring to make it look pretty. There are no chemicals or any other ingredients that would be unsafe for human consumption.
