Five-Peel Powder – Wu Pi San

Five-Peel Powder – Wu Pi San

A formula to drain damp.

A formula to drain damp. While it’s a classic for skin edema, I use most often for Spleen Qi deficiency with long term, stubborn damp. It’s a draining formula so it’s often combined with tonic herbs to balance it out for weak constitutions. The formula in this photo was modified for someone with one week of dizziness, fatigue and a heavy downward bearing sensation.

Dampness messes with the mind and body both and that looks like:

  • sensations of physical heaviness and mental heaviness (depression)
  • water retention/edema and a foggy mind
  • difficulty concentrating, circular thinking, lack of clarity and discernment
