Yuan Shen Root Classic Formulas — Natural Herb Library

Primary Actions

Clears heat and benefits the throat - Yuan Shen is an alternate name for Xuan Shen and is used for painful swollen throat, voice loss, and toxic heat lodged in the upper burner.
Enriches yin and cools deficiency heat - it is useful when lingering fever, night sweating, dryness, or restlessness show that heat has damaged fluids.
Softens hardness and disperses masses - like Xuan Shen, it is a classic herb for scrofula, nodules, and hard swellings in the neck or glandular regions.

Yang Yin Qing Fei Tang - classic throat and dryness formula using Xuan Shen or Yuan Shen logic to nourish yin while reducing toxic throat swelling.
Qing Ying Tang - warm-disease formula in which the herb cools nutritive-level heat and protects fluids.
Xiao Luo Wan - classic nodules and scrofula strategy built around the herb's salty-softening effect.

Traditional naming varies between Xuan Shen and Yuan Shen, but the medicinal identity remains Scrophularia root.
Classical formula literature repeatedly places the herb in throat, heat-toxin, and nodule-dispelling strategies.
Its yin-nourishing side is especially important when heat has already consumed fluids and produced irritability or night sweating.
