Today let's talk about a genuine health preservation principle—when it comes to kidney deficiency, in eight or nine cases out of ten, you've got to trace the root to liver blood deficiency. You may ask why? Our ancestors long ago said "the liver and kidneys share the same origin." These two organs are like grasshoppers tied to the same string—when one is deficient, the other is bound to suffer.

First, let's discuss how liver blood gets depleted. Look at people nowadays—staring at computers during the day and scrolling through phones at night, eyes practically glued to screens. Reading road signs while walking, checking blueprints while working, even getting angry requires mobilizing liver qi—all of this relies on liver blood to sustain it. Like a phone's battery—drained from heavy daytime use—if you don't charge it sufficiently at night, it'll shut down the next day. If liver blood remains in chronic deficit, the body will automatically "rob Peter to pay Paul," mobilizing kidney essence to cope. Over time, kidney deficiency naturally comes knocking.

If you carefully observe people around you, those with kidney deficiency nearly always experience blurred vision and difficulty seeing clearly, have a temper like firecrackers that ignite instantly, and suffer from alarmingly poor memory. These aren't coincidences. Traditional Chinese Medicine explains that "the liver manifests in the eyes" - liver blood deficiency first reveals itself through the eyes. "The liver governs emotions," so major mood swings are also signs of liver blood depletion. As for memory decline, that occurs when both liver-kidney essence and blood fail to keep up.

When it comes to kidney tonification, Wuzi Yanzong Wan is currently selling like hotcakes, but in terms of actual effectiveness, Guishao Dihuang Wan and Yiguan Jian take the lead. Guishao Dihuang Wan contains two key herbs - Chinese Angelica (Danggui) and White Peony Root (Baishao) - which act like a "fast charger" for liver blood, providing particularly strong blood-tonifying and liver-nourishing effects. Yiguan Jian is even more remarkable, adding Sichuan Chinaberry (Chuanlianzi) among its yin-nourishing and blood-tonifying herbs. This works like an "exhaust valve" for liver qi, ensuring the supplemented liver blood doesn't stagnate inside, allowing proper circulation where needed and nourishing areas that require support.

If you've tried various kidney tonifying formulas without results, or even experience heat symptoms after supplementation, there's an 80% chance you're supplementing the wrong way. In such cases, try the simultaneous liver-kidney tonification method - it's like plugging in both a charger and a power bank for a nearly depleted phone, often proving much more effective than supplementing just one system. However, a reminder: Chinese herbs must be used according to syndrome differentiation. For actual regulation, it's best to consult a TCM practitioner for pulse diagnosis rather than trying to figure it out yourself.
