Natural ginger spice is available in powdered form from Swanson Health Products, Ludden's Natural Products and iHerb.com, as of 2015. These three vendors sell organic powdered ginger root for use as a spice in recipes or herbal teas and blends.
Swanson Health Products offers certified USDA organic ginger in whole root, cut-and-sifted, powdered or crystalized forms on its website, SwansonVitamins.com. The company offers a satisfaction guarantee that covers the cost of the product and return shipping if customers are unpleased with their purchases. Satisfied customers can set up automatic reorders for regular delivery of fresh spices.
Ludden's Natural Products carries fair-trade certified organic powdered ginger, and bulk orders of products from the company's website, LuddensNatural.com, ship for free when part of an order totaling $325 or more. The company lists suggested retail pricing along with its discounted rates, so customers can quickly gauge their savings on each purchase, and Ludden's Natural Products also lists the origins of many of the spices it sells online.
Shoppers who turn to iHerb.com benefit from clear expiration dates that confirm the freshness of the herbs and spices available through the company's online store. Customer reviews help shoppers learn more about the products sold by the online retailer.
