A ceramic earthenware pot is ideal for brewing medicinal herbs. Since many medicinal herbs contain tannins, avoid iron containers, which tend to create water-soluble salts. Also, the components of some herbs can be altered by the oxidation of iron. Stainless steel, which contains a lot of iron, should also be avoided. The far-infrared rays emitted from the ceramic quickly extract the components of medicinal herbs and tea leaves, shortening the brewing time. Can be used directly over a flame. *Not compatible with IH cooktops. Contents: (Made in Japan) Paper box included.
