Most of Dr. Sebi’s products have an estimated shelf life located at the bottom of each product, but the herbs can easily surpass that freshness period. We recommend storing the products in a dry, cool place for prolonged shelf life. We recommend taking the tonics as soon as possible, but they typically have a shelf life of 3 months. They must be refrigerated at all times or, if needed, kept in a cool environment until available for refrigeration. Be sure to shake your tonic to ensure the consistency remains the same as when you first opened it. Please stop consuming a product if you see mold, smell a foul stench, or hear fizzling.
