[Collected Annotations] Luo Qianfu stated: This formula is designed for cases of Yang deficiency and Yin weakness, where essence cannot ascend to nourish the eyes. Therefore, in ophthalmology, it is often used alongside the Ci Zhu Wan (Magnetite and Magnetized Iron Pill) from *Qianjin Fang*, treating similar syndromes. However, while Ci Zhu Wan belongs to sedating and anchoring herbs, this formula belongs to tonifying herbs. The *Zhen Jing* (Needle Classic) states: The essence and qi of the five zang and six fu organs all ascend to the eyes to form visual acuity. Thus, the clarity of vision results from the harmonious integration of Yin and Yang. If the Liver and Kidney are deficient, Yin essence is insufficient to consolidate essence and fails to nourish the Shen Shui internally. If the Spleen and Lung are deficient, Yang Qi is too weak to secure Yin, causing the Shen Guang (visual spirit/light) to scatter externally, resulting in dilated Shen Shui and diplopia. The therapeutic principle for this condition focuses on the Ying (Nutritive) aspect in the Liver, the Master role of the Kidney, and the Harmonizing function of the Spleen. By combining the Yin of the Kidney and Spleen to allow the Liver Qi to diffuse freely, essence can be returned to both eyes, restoring clear vision as distinct as day and night. This formula first tonifies the Liver and Kidney using a group of Yin-nourishing herbs including Tian Dong, Mai Dong, Di Huang (both raw and prepared), Tusizi, Gouqi, Wuweizi, Niuxi, and Roucongrong, to strengthen Yin, fill essence, consolidate Qi, calm the Spirit, and nourish Blood. This strengthens the source of Water (Kidney Yin) to generate fluids. Subsequently, Renshen, Zhi Gancao, Fuling, and Shanyao are used to cultivate the Middle Jiao (Spleen/Stomach) to harmonize Yin and Yang. Auxiliaries include Jili, Ganju, Chuanxiong, Zhike, and Fangfeng to soothe the Liver and promote Qi movement; Qingxiangzi and Caocuoming to resolve stagnation and disperse accumulation; Huanglian, Wuxi, and Lingyangjiao to clear fire and drain heat. However, the unique efficacy of Shihu lies in its ability to harmonize the Spleen and Kidney, clearing and guiding the action, ensuring that the function of ascending essence and brightening the eyes achieves unity among the viscera. The reason for making pills is that tonifying the upper and treating the lower requires a slow, sustained effect rather than a rapid one.
