CHAPTER 14 Painful Periods
As we have seen in Chapter 2 on physiology, four different phases may be identified in each menstrual cycle. During the pre-menstrual phase, Yang rises and Liver-Qi moves in preparation for moving Blood during the period. Thus, a proper movement of Liver-Qi and Liver-Blood is essential for a pain-free period. If Liver-Qi stagnates, it may cause pain, especially before the period, while if Liver-Blood stagnates, it causes pain during the period. Stagnation is therefore the most important pathological condition causing painful periods: even in deficiency conditions when the pain is mild, it is some element of stagnation that causes it.
The earliest mention of Painful Periods is probably in the Synopsis of Prescriptions of the Golden Cabinet which says: “If a woman has irregular periods with abdominal pain and fullness, and the periods are irregular, use Tu Gua Gen Powder”.1
Another passage in the same book appears to describe an episode of severe dysmenorrhoea from Cold:
When Cold invades the Lower Burner the menses may become scanty and painful with a dragging pain in the vagina and a feeling of cold in the abdomen … there is an acute pain on Qichong [ST-30] … there may be sudden vertigo and the woman may pass out … this is a gynaecological problem and is not due to an attack of evil spirits …2
Aetiology
External Cold and Dampness
The Liver pertains to Wood, it stores Blood and it hates wind and cold most of all. During menstruation the space between skin and muscles (cou li) is wide open, when this is invaded by wind and cold Liver-Qi stagnates and the passages of the menses become obstructed.3
Pathology
The main patterns causing Painful Periods are therefore:
Stagnation of Liver-Qi is often secondary to or accompanied by Liver-Blood stasis (as discussed at length in Chapter 3 on pathology): when this is the case, the pulse may not be Wiry at all but Fine or Choppy (and perhaps slightly Wiry on one side) and the tongue may be Pale (from Blood deficiency).
Diagnosis
Treatment principles
From the point of view of Manifestation (Biao) the central pathology of Painful Periods is a disharmony of the Penetrating Vessel and Sea of Blood. Hence the main principle of treatment for the Manifestation is to regulate the Qi and Blood of the Penetrating Vessel. As discussed in Chapter 3 on pathology, the Penetrating Vessel is the Sea of Blood. It arises from the Uterus and is therefore always involved in Painful Periods. This vessel is particularly prone to stagnation of Qi and Blood in the abdomen and many of its points (especially KI-14 Siman) eliminate stagnation. The Qi of the Penetrating Vessel is prone to rebel upwards from the abdomen towards the chest giving rise to a feeling of oppression of the chest.
Other points related to the Penetrating Vessel in treating painful periods are LIV-3 Taichong, ST-42 Chongyang and ST-30 Qichong. LIV-3 Taichong is the most important one to affect the Penetrating Vessel: by moving Liver-Qi, it regulates the Penetrating Vessel, subdues its rebellious Qi and invigorates Blood. The association between this point and the Penetrating Vessel is so close that sometimes the old classics call this vessel Taichong. In fact, the very first chapter of the Simple Questions, in describing the 7-year cycles of women, says: “At 14, the Heavenly Gui arrives [i.e. the menses], the Directing Vessel is open and the Taichong vessel is flourishing.”5 The ‘Taichong vessel’ is the Penetrating Vessel. ST-42 Chongyang also regulates Blood within the Penetrating Vessel and eliminates stasis due to the relationship between this vessel and the Bright Yang. ST-30 Qichong is one of the most important points on the Penetrating Vessel and strongly moves Qi and Blood in the abdomen. Its other name, Qijie, means ‘avenues of Qi’, referring to the channels and vessels of the abdomen which the Penetrating Vessel influences.

a Prescription
This is a famous formula from the Synopsis of Prescriptions from the Golden Cabinet by Zhang Zhong Jing (AD 220), which is primarily for Cold obstructing the Uterus. The rationale behind it is as follows. When Cold obstructs the Uterus, it makes Blood stagnate. When Blood stagnates, new Blood has nowhere to go and it cannot be contained in the Uterus: this induces a deficiency of Blood. A longstanding Blood deficiency may give rise to some Empty-Heat signs, which may mistakenly be interpreted as Heat signs; but the Pale-Purple colour of the tongue clearly indicates that this is not so. In fact, the original text refers to a parched mouth and lips as the symptoms of Empty-Heat from Blood deficiency.10 When used for its proper pattern of longstanding internal Cold occurring against a background of deficiency and leading to stasis of Blood, this formula is very effective. An essential sign for its use is that the tongue-body colour be Pale or Bluish-Purple.
