Whenever the body has Dampness or Phlegm, the Spleen is always the first Organ to be checked, because it is responsible for Body Fluids metabolism. The Spleen transforms, transports, and distributes drinks along with food Essence and Grain Qi.

When these functions are impaired, Damp-Phlegm forms and accumulates. If it stores in the Uterus, the Directing and Penetrating Vessels are obstructed. Then there is not enough Blood flows to the Uterus or the flow gets delayed all the time, hence the symptoms of scanty period, late period or even complete absence of period.

Often patients suffering from this pattern tend to be overweight or Obesity. It is because the Damp-Phlegm accumulates also in abdominal area and cause a fat and soft belly as well as pain and oppression there. As a rule of thumb, Chinese Medicine practitioners see that overly thin women with scanty or late periods will often have Blood Deficiency while overweight ones are more due to Damp-Phlegm.

Patients suffering from polycystic ovary syndrome (PCOS) also often have scanty periods due to Damp-Phlegm and they are often obese (although it might not necessary for all cases).

For Scanty Period, use Cang Fu Dao Tan Wan and Xiong Gui Er Chen Tang. For Late period, use Xiang Sha Liu Jun Zi Tang and Xiong Gui Er Chen Tang. When the condition is as severe as absence of menstruation, all above formula can be used to treat Damp-Phlegm, together with Bu Zhong Yi Qi Tang, which is used to tonify the Spleen.

Many patterns are the underlining reasons for the above three gynecology diseases. However, Damp-Phlegm is the most difficult one to treat as it often takes several years to expel the Damp-Phlegm Evil.
