      Jujube is so tasty to make soup or just eat it like dried nut. So, please don’t make it become more of a chore than a pleasure by eating it in the forms of powder and capsule. It is so boring. And if you need more opinion from me, feel free to let me know.

  7. Julio K

    If red dates are so good for spleen and stomach deficiencies, why is it difficult to digest? wouldn’t this be a contradiction??
    if so, what can be done to make it more digestible? cooking perhaps or adding ginger or some other moving herbs (chen pi or Magnolia bark maybe)
