Male *Xu Lao* (Deficiency Consumption) has been detailed in the *Xin Fa* (Essential Methods), while female damage (*Nü Sun*) involving Yin and Blood transforms into *Feng Xiao* (Wind Wasting, a type of consumption characterized by emaciation); or it may arise from post-illness constitution being inherently weak, presenting as amenorrhea, chronic cough, and *Xue Feng Lao* (Blood-Wind Consumption).

[Note] The treatment methods for male *Xu Lao* have been detailed in the "Deficiency Consumption Section" of *Za Bing Xin Fa Yao Jue*. Female consumption often results from damage to Yin and Blood, either due to illness injuring Yin and Blood, or inherent deficiency of Yin and Blood from birth. However, only when symptoms such as Yin deficiency with bone-steaming fever, blood exhaustion with amenorrhea, and persistent chronic cough are present, is it termed "Lao" (Consumption). If there is no cough, it is termed "Xu" (Deficiency), not "Lao". *Feng Xiao* is an ancient name for a type of consumption. Females are termed "Xue Feng Lao" because the *Nei Jing* states: "Lao Wind originates below the lungs," meaning that when a person with deficiency contracts wind pathogen, the Lungs are affected first, thus initially presenting with cough; if one does not first resolve the wind pathogen but proceeds directly to tonification, it is inevitable that chronic cough will evolve into consumption, hence the term "Xue Feng Lao".

At age forty-nine (seven sevens), women's Tian Gui (substance promoting reproductive maturity) exhausts, and the Earthly Path (menstrual flow) ceases; this is normal, and menstruation should stop. If menstruation continues without other symptoms, it indicates excess blood, and medication should not be used to forcibly stop it. If menstruation has ceased and then returns after one year or three to five years, one must examine whether there is a cause or none, identify which pathogen is interfering, and treat according to the specific symptoms.

For unmarried girls, if menstruation starts and then stops again, provided there is no discomfort, it is not considered a calamity or disease; this is likely "Bi Nian" (avoidance year, where menstruation occurs once a year) due to insufficient Qi and Blood. If signs of wasting and deficiency appear, it constitutes "Tong Lao" (Juvenile Consumption) with blood exhaustion and amenorrhea in unmarried girls, which is mostly difficult to treat, hence it is said that their fate is pitiable.

The treatment for nuns, widows, and secluded women differs and should not be treated identically to ordinary women. If the pulse is wiry and extends beyond the cun position at the wrist, it indicates unfulfilled aspirations and emotional distress causing illness. When regulating menstruation, if this etiology is not recognized first, how can one clarify the complex and indistinct symptom patterns? Treatment should focus on harmonizing the Liver, regulating the Spleen, opening up stagnant Qi, and clearing the Heart, adjusting according to symptoms to achieve success.

[Note] "Shi" refers to Daoist nuns. "Ni" refers to Buddhist nuns. "Shi" refers to unmarried women. "Gua" refers to young widows. "Yi Hu Zhi" means the treatment differs from ordinary women. For instance, finding a wiry pulse extending beyond the cun position indicates unfulfilled will, signifying an illness caused by emotional factors. To regulate all menstrual disorders in women, one must first recognize this cause to understand these complex, emotion-induced conditions. Treating this syndrome requires harmonizing the Liver and Spleen, resolving depression, and clearing the Heart, applying treatments based on specific symptoms, which will naturally yield results.
