5:1 Formulas are the only lab tested formulas in the world and certified to be free of pesticides, bacteria, solvents, yeast, mold, heavy metals, and yeasts. Who needs clean room certifications when you make lab-certified organic formulas? Not only are we the only lab tested formula in existence, 5:1 formulas are made with the least amount of ingredients and therefore minimize all potential heat by-products. We only use organic vegetable glycerin sourced from coconut oil and one herb. Valerian Root, Palo Santo, Yerba Mate, Lavender, and Chamomile are our 5 best formulas. Valerian Root is deeply relaxing. Palo Santo, meditative. Yerba Mate will energize fast. Don't trifle with untested products that are made and shipped from China. The 5:1 Formulas are made in America by Americans. We are the only self regulating brand in a highly unregulated market. That's because we intend to provide new formulas and technology to the foundations of traditional herbalism.
