Su Kenan nodded seriously, memorizing Lu Xuan's words.

Lu Xuan, on the other hand, no longer discussed the matter of pulse diagnosis and instead focused on leucorrhea: "Leucorrhea refers to the significant increase of vaginal discharge in women, accompanied by changes in color, quality, and odor. Some may experience vaginal and vulvar dampness, redness, swelling, and itching, while others may have significantly reduced or absent vaginal discharge, all of which can be collectively referred to as leucorrhea symptoms.

Leucorrhea symptoms can be categorized into physiological and pathological phenomena. Increased discharge around menstruation, during ovulation, or pregnancy is a normal physiological occurrence. However, an increase in discharge outside these periods, along with symptoms, is termed leucorrhea disease."

"Have you read any medical books on this topic in the past few days?" Lu Xuan asked.

Su Kenan nodded: "Read some."

"Do you know which medical book first documented leucorrhea?"

"Suwen."

"Do you remember the content?"

Su Kenan hesitated for a moment, then ultimately shook her head.

Lu Xuan was not surprised, as not everyone has a photographic memory like him. It was commendable for Su Kenan to recall that the earliest record of leucorrhea was in Suwen. An average medical student might not even have been able to answer that.

"Leucorrhea was first mentioned in the 'Suwen·Bone Hollow Chapter' as 'Ren Meridian diseases...women's leucorrhea and abdominal masses.'"

Lu Xuan patiently explained: "The 'Suwen·Ancient Naive Theory' also mentions 'women, in their fourteenth year, experience menarche, the Ren Meridian becomes active, and the Liver Meridian flourishes, resulting in menstruation and fertility.'

During this period, there will be noticeable secretions, mediated by the spleen's function of transportation, the kidney's function of storage, the Ren Meridian's control, and the binding of the Girdle Meridian, manifesting at the genital orifices.

This aligns with the words of the Chinese medicine febrile diseases expert Wang Mengying, 'Leucorrhea is inherently present in women since birth; it is naturally moist and not a disease.'"

In cases of leucorrhea disease, the quantity is excessive, the discharge comes in five colors, and the smell is pungent and unpleasant, thus constituting leucorrhea disease.

Leucorrhea disease in women is a common and frequently occurring condition, often associated with irregular menstruation, amenorrhea, genital itching, infertility, epilepsy, etc.

As early as the Warring States period, there existed a specific term for physicians treating leucorrhea. The legendary physician Bian Que encountered a noblewoman in Handan, who was a renowned leucorrhea physician. This shows how much importance traditional Chinese medicine places on women's menstruation, pregnancy, and childbirth. Ancient Chinese medicine has accumulated rich experiences on women's diseases, providing significant reference value for us Chinese medical practitioners."

At this point, Lu Xuan paused for a moment before continuing: "Excessive leucorrhea was historically known as 'white mold,' 'red mold,' 'red and white mold,' 'white overflow,' 'red overflow,' 'red and white overflow,' 'discharge of white substance,' etc.

Zhang Zhongjing's 'Essential Prescriptions of the Golden Cabinet·Miscellaneous Diseases of Women Pulse Syndrome and Treatment' mentions 'in women, if menstrual flow stops and… discharge of white substance, alum stone pill is the principal treatment.';

'Treatise on the Origin and Manifestation of Various Diseases·Women's Miscellaneous Disease Syndrome·Leucorrhea Syndrome' names leucorrhea disease, categorized into five colors;

Liu Wansu in 'Suwen Secret Records on Origin of Diseases·Attached Leucorrhea' states 'when the moisture and heat in the lower part under the Ren Meridian are extreme, fluids overflow as leucorrhea'; Yin-Nourishing School's founder in the Yuan Dynasty, Zhu Danxi believes 'excessive leucorrhea is often related to damp-heat, suggesting in treatment to use drying as the primary approach, supplemented by lifting and nourishing deficiencies';

'Complete Book of Jingyue Women's Rules Leucorrhea, Dreams, and Night Emissions' points out 'heart fluttering', 'excessive desire leading to slipperiness', 'unnatural intercourse', and 'deficient cold not firmed up' as roots of kidney injury causing excessive leucorrhea. 'Fu Qingzhu's Gynecology·Leucorrhea' lists leucorrhea disease at the forefront of the book, analyzing its pathogenesis by different colors of discharge: white, yellow, red, green, and black, indicating leucorrhea is an important symptom for women in their late twenties.

Throughout history, medical scholars' understanding of leucorrhea disease has been fairly consistent. They believe it frequently arises from deficiency or damage to the spleen and kidneys, leading to internal accumulation of damp-heat that affects the genital region and uterus and disrupts the stability of the Ren and Girdle Meridians.

However, while dampness is a primary cause of this disease, it does have internal and external distinctions.

Why is that?

The liver, spleen, and kidneys are causes of internal dampness, such as spleen deficiency causing loss of transport function, internal generation of dampness, kidney yang deficiency leading to abnormal qi transformation and internal damp stagnation, liver depression overacting on the earth, and liver fire with damp-heat descending. These are causes of internal dampness.

External dampness often results from prolonged residence in humid locations, wading in water, or being exposed to rain, engaging in unclean intercourse, or intercourse during menstruation, leading to moist evil toxins affecting the cervix, causing erosion, vaginal inflammation, and related conditions."

After speaking in one breath, not only the speaker but also the listeners felt their scalp tingle.

At this moment, Ji Xiuwen already felt his scalp tingling.

He stared blankly at his old classmate, somewhat doubting whether his old classmate was even human, but rather a repository of traditional Chinese medicine books.

The content of ancient medical books is not written in vernacular, making them often obscure and difficult to understand, unlike the straightforwardness of vernacular, let alone memorize; even reading directly from the text can be tongue-twisting.

But for Lu Xuan, nothing is obscure or difficult to understand, nothing is tongue-twisting, everything seems as if it doesn't exist at all.

The most critical part is that he simply couldn't comprehend what method his old classmate uses to memorize all of these contents.

It's important to note that when Lu Xuan gives examples, he's not just citing one medical book; he discusses relevant records from any associated medical text.

Remembering the books and their contents is one thing, but to recall even specific parts with such clarity is truly beyond explanation.

Is this something humans can achieve?

Ji Xiuwen began to question his life a bit.

He couldn't help but glance at Su Kenan, thinking perhaps the naive girl never thought much about it and simply believes Lu Xuan is amazing; she seems to be nearly becoming like Lu Xuan.

Upon realizing this, Ji Xiuwen suddenly felt as if he had discovered some remarkable secret. No wonder the teaching was so meticulous; it turns out it's because she's becoming Lu Xuan's likeness?

With that thought, Ji Xiuwen turned to look at his old classmate.
