Before You Add Hu Zhang to Your Cart

A few quick checks can help you avoid ordering the wrong form or package size.

  1. Confirm the form. Are you ordering cut material, whole-herb powder, or an extract? These are different preparations.
  2. Check the package weight. Review the size shown on the specific listing so you know how much product you are purchasing.
  3. Review the brand and ingredients. Product formulations and additional ingredients may differ between manufacturers.
  4. Look for applicable certifications. If organic status is important to you, confirm that the individual item is identified as certified organic rather than assuming every Hu Zhang product has the same designation.
  5. Read the product directions. Follow the instructions and precautions for the exact preparation you purchase.
