There are many causes of eye fatigue.
Some cases are due to overuse, some to liver qi stagnation, and others to issues with the eyes themselves.
Previously, Zhang He's eye redness had persisted for half a year.
It had caused damage to his eyes.
Therefore, using foxtail grass to treat him—to brighten his vision and relieve fatigue—was a symptomatic treatment.
However, Wang Zhibao's eye fatigue was caused by a kidney essence deficiency, which left his eyes unnourished.
His clinical symptoms were dry eyes with few tears, accompanied by soreness in his lower back and knees, mental exhaustion, insomnia, and forgetfulness.
"Open your mouth and stick out your tongue."
"Ah~"
His tongue was pale with a thin coating.
Then, he checked his pulse.
The pulse was faint and weak.
Under these circumstances, foxtail grass couldn't be used.
Li Xu adjusted the prescription he had just written for Wang Zhibao.
He used a modified version of the Golden Cabinet Kidney Qi Pill formula.
