Flax seed gel. Google it. I boil 1/4 cup flax seeds in 2 cups water. As a white top forms and the seeds slot on top rather than sink, pour it into a strainer. Then mix FSG with 1 tbsp each glycerin and jojoba oil. But you don't have to. You can also add a few drops of essential oils like tea tree, lemongrass and rosemary (ie 3 drops each of lemongrass, tea tree and rosemary). Google this to see other recipes. Must be refrigerated!
