By far one of the most popular organic tampon options on Amazon, Organyc 100% Certified Organic Cotton Tampons ($6) are made of 100 percent organic cotton, free of dyes, fragrances, chlorine, and rayon, and feature a 90-percent plant-based applicator. Offered in normal, super and super plus absorbencies, many reviewers note these tampons don't make them itch and are great for those sensitive to normal tampons.
