Introduction
"Levels of Medicine"
This page is cultural documentation, not medical advice.
A Qing-dynasty comprehensive medical encyclopedia by Dong Xiyuan (Yongzheng-Qianlong reign era, ca. 1723–1795), completed around 1743. A clinical text organized by disease category and treatment method.
The Yiji is a late-Qing clinical compilation by Dong Xiyuan, organized around "diseases + treatment methods" (病证 + 治法). The text is the canonical source of Qǐ Jú Dì Huáng Wán (杞菊地黄丸, "Lycium-Chrysanthemum Rehmannia Pill"), a formula that adds Gǒu Qǐ Zǐ (Lycium fruit) and Jú Huā (chrysanthemum) to the canonical Liù Wèi Dì Huáng Wán (Six-Ingredient Rehmannia Pill), redirecting the "tonify-kidney-yin" core toward a "tonify-liver-and-kidney, brighten-the-eyes" indication. The formula is, in modern Chinese pharmacy, one of the most frequently prescribed 中成药 for "liver-kidney-yin-deficiency with eye fatigue" presentations. The Yiji is, in short, a representative Qing-era "classical-formula + small-modifier" reference.
Historical background
The Yiji (Levels of Medicine) was compiled by Dong Xiyuan during the Yongzheng–Qianlong reign era of the Qing dynasty and completed around 1743.

The text is the canonical source of Qǐ Jú Dì Huáng Wán (Lycium-Chrysanthemum Rehmannia Pill), which adds Gǒu Qǐ Zǐ and Jú Huā to the canonical Liù Wèi Dì Huáng Wán (Six-Ingredient Rehmannia Pill), redirecting the classical "tonify-kidney-yin" core toward a "tonify-liver-and-kidney, brighten-the-eyes" indication.…
