Wildly Organic Goji Berries are never sprayed with herbicides or pesticides and the berries are not fumigated, sweetened, or adulterated in any way. The goji berries are dried using large commercial driers inspected by organic certifiers. Not only do our goji berries have the organic certification and other inspections, but before we purchase these berries we have them tested for multiple organic compounds, which are found in America, Asia, and Europe. We want positive assurance that these berries are chemical-free, and only if they pass this test are they shipped to America. Our Goji Berries sourced in China arrive ready-to-use in 8 ounce vapor-barrier, resealable packaging to maintain freshness. All packaging may include an oxygen absorber.
