I'm here to talk with you about a formula called Feng Sui Dan. At first glance, the name sounds like some secret elixir from a martial arts drama that seals internal energy—pretty mysterious. But don't let the name fool you; it has real, tangible effects. With just three herbs in the formula, it can tackle frustrating issues like fire failing to return to its source and an insecure essence gate.

In today's society, staying up late has become the norm for many people. Just like night owls, they don't sleep at night and struggle to get up in the morning. But staying up late for too long brings problems. Kidney yin deficiency leads to deficient fire rising upward—it's like a kettle where the flame underneath is too strong, and the water turns into steam that floats upward. At this point, a person may experience mouth sores, toss and turn unable to sleep at night, frequent night sweats and nocturnal emissions, soreness in the lower back, weakness in the legs, and overall lack of energy.

When faced with such a situation, one must not only focus on tonifying the kidneys. It’s like building a house—if the foundation is unstable, no matter how well the structure above is built, it’s useless. We need to guide the floating deficiency-fire back to the kidneys, restoring balance to the body.

Fengsuidan consists of three herbs: Phellodendron, Amomum, and Licorice. Phellodendron, with its cold nature, is specifically used to reduce fire. It acts like a fire extinguisher, instantly extinguishing the deficiency-fire that rises to the head and face, calming the body's internal heat.

Amomum, on the other hand, has a warm nature and acts like a considerate caretaker. It nourishes the spleen and stomach and unblocks the Middle Jiao. The Middle Jiao functions as the body's transportation hub; the essence from the five zang and six fu organs must pass through here to return smoothly to the kidneys. By unblocking the Middle Jiao, Amomum guides this essence back to the kidneys, stabilizing the kidney essence.

Then there's Licorice, which plays a significant role. Licorice harmonizes and strengthens the spleen, much like adding lubricant to the body's engine, restoring vitality. Moreover, it can harmonize the effects of the other herbs, enhancing their medicinal properties, acting like a mediator to allow the other two herbs to work more effectively. At the same time, it prevents the excessive cold nature of Phellodendron from harming the spleen and stomach, protecting these vital organs.

This combination, on the surface, may seem like a conflict between cold and heat, akin to two groups of people fighting. However, in reality, the sovereign herb Phellodendron amurense (黄柏) is specifically intended to clear heat and reduce fire, the minister herb Amomum villosum (砂仁) is used to regulate qi, and licorice (甘草) acts like a referee, harmonizing the cold and warm properties of Phellodendron amurense and Amomum villosum, promoting the balance of water and fire within the body, ultimately achieving a state of equilibrium.

Prominent modern traditional Chinese medicine expert Li Ke has praised this formula, describing it as "simple in composition yet highly effective," meaning that although it uses few herbs, its effects are particularly remarkable. Therefore, if you also suffer from health issues caused by staying up late, it might be worthwhile to learn more about Feng Sui Dan. It could potentially bring unexpected benefits to you.
