When Lu Xuan was prescribing medicine for the young woman, Ji Xiuwen hesitated to speak.

To be honest, he hadn’t encountered this situation before, even though he’d been Lu Xuan’s assistant for quite some time.

However, he had heard about it back in school.

Thinking about this, Ji Xiuwen smiled and said, "I remember hearing my mentor mention dysmenorrhea in school, and he specifically talked about female students without boyfriends. I thought he was joking, but I didn’t expect it to be true."

"There is indeed such a thing, but it’s quite rare. Not all dysmenorrhea is related to having a boyfriend or not," Zhang Guangli knew a bit about this and replied.

"Dean Zhang, could you explain it to me?" Ji Xiuwen showed a curious expression.

Zhang Guangli pondered for a moment: "It’s not that I cannot explain, but I fear my understanding isn’t as deep as Dr. Lu’s. Instead of me telling you, it would be better to have Dr. Lu explain it."

"Besides..."

"To be honest, my understanding of this topic isn’t extensive."

After speaking, the two exchanged a glance, both turning their gaze towards Lu Xuan, who was busy writing a prescription.

Although Lu Xuan was diligently writing the prescription, he heard their conversation clearly. Sensing the gaze upon him, Lu Xuan quickly finished writing, put down his pen, cleared his throat, and said, "Speaking of this, we have to talk about Yin and Yang."

Yin and Yang?

Ji Xiuwen frowned slightly.

Zhang Guangli nodded discreetly.

The concept of Yin and Yang has permeated the entire field of traditional Chinese medicine.

Originally, the woman who was holding the prescription and preparing to leave, upon hearing this, sat back down.

She had come to Huian Pharmacy based on recommendations. Yesterday, she heard that Dr. Lu not only consulted patients but also explained some traditional Chinese medical philosophies, which she initially doubted. But now, she couldn’t help but believe it.

She even began to feel a subtle curiosity about traditional Chinese medicine and decided to sit down and listen carefully.

Everyone sat upright.

Some patients near Lu Xuan, afraid of missing out, were all ears at this moment.

"In traditional Chinese medicine, the concepts of Yin and Yang are extremely important. There’s even a saying: When Yin and Yang are imbalanced, illness ensues. An imbalance in Yin and Yang causes illness. Excessive Yin leads to Yang illness, excessive Yang leads to Yin illness. Excessive Yang causes heat, excessive Yin causes cold. Extreme cold leads to heat, extreme heat leads to cold."

"Here, I have to mention a concept called the pulse of a healthy person."

"What is the pulse of a healthy person?"

Lu Xuan asked and answered his own question: "From the perspective of traditional Chinese medicine, you must understand what is considered an illness? Imbalance in Yin and Yang is considered an illness. Therefore, people gradually perceive that in traditional Chinese medicine, everything is due to imbalances in Yin and Yang.

However, if one can truly discern Yin and Yang, then the wisdom of traditional Chinese medicine comes to life. So, regardless of whether a person is male or female, old or young, tall or short, fat or thin, whether they are Chinese or foreign, as long as they are relatively healthy, they should be in a state of relative balance according to the principles of Yin and Yang.

Regardless if they’re male or female, old or young, tall or short, fat or thin, as long as they are relatively balanced and relatively healthy, they are in a state of Yin and Yang balance. Among all relatively healthy groups, the unchanging principle is, ’When Yin remains balanced and Yang is hidden, the spirit thrives; when Yin and Yang separate, the vital energy perishes.’

Traditional Chinese medicine believes that an imbalance in Yin and Yang in the human body leads to illness, but some people believe that the theory of Yin and Yang is merely philosophy, claiming that traditional Chinese medicine uses philosophy to treat diseases, considering it as superstition. Is that really the case? What exactly do Yin and Yang mean in traditional Chinese medicine?"

Everyone fell into contemplation, seemingly pondering this question.

The concept of Yin and Yang, whether learned or unlearned in traditional Chinese medicine, whether understood or not understood, everyone has almost heard of this term.

In most circumstances, this term is intricately linked to superstition.

Yet, in the context of traditional Chinese medicine, it is somewhat related but not too closely linked to superstition.

Is traditional Chinese medicine superstition?

Clearly not.

Its efficacy is unquestionable, as evidenced by its legacy over thousands of years. Traditional Chinese medicine has little to do with superstition. Though its medical rationale may not be grasped by everyone and lacks the scientific nature of Western medicine, this unscientific practice has resolved many ailments that Western medicine could not, saving countless lives.

This is an undeniable fact.

"Inside our bodies, the warm, energetic, activating force for the functionality of our organs is called Yang Qi. The nourishing, replenishing force is called Yin Qi.

Every organ has Yin and Yang, and only through balance can one achieve health, ’Balance in Yin leads to hidden Yang, resulting in a thriving spirit.’

Imbalance in Yin and Yang results in disease."

As everyone contemplated, Lu Xuan’s voice broke the silence: "We can balance Yin and Yang using food or medicine."

Ji Xiuwen, having studied traditional Chinese medicine, understood this; he had heard Lu Xuan discuss this type of knowledge before, so it wasn’t outside his knowledge base.

Zhang Guangli knew even more.

Balancing Yin and Yang isn’t solely reliant on medicine; food can achieve this balance as well.

However, the others seemed confused, displaying evident puzzlement on their faces.

This was apparent from the frowns on their foreheads, indicating that without further explanation, few people might grasp the concept.

So, Lu Xuan glanced at the crowd, pondered for a moment, and decided to use straightforward language to clarify this part of the knowledge: "For example, watermelons grow under the direct sunlight. Eating watermelon helps cool down, relieve summer heat, generate fluids, and quench thirst. To maintain internal and external balance of Yin and Yang, it must possess anti-heat properties, which is why consuming it during such seasons poses no problems.
