A traditional formula for deeper nourishment, dryness, healthy ageing, and kidney health
Nourish Root Yin (Liu Wei Di Huang Wan) supports the body when long-term depletion or ageing leads to dryness, fatigue, heat signs, and reduced resilience. Qian Yi first recorded it in Xiao Er Yao Zheng Zhi Jue ( Craft of Medicinal Treatment of Childhood Diseases Patterns ) in 1119. It began as a paediatric formula. Later, it became one of the best-known traditional formulas for nourishing Liver and Kidney Yin. It remains a trusted choice when the body feels worn down, dried out, or less well supported with age.
When to use it
In Traditional Chinese Medicine, practitioners choose Nourish Root Yin when the body no longer has enough cooling, moistening, and restorative support. Dryness may begin to increase. Night sweats may appear. The mouth or throat may feel dry. Some also notice dizziness, tinnitus, lower back weakness, tired legs, vaginal dryness, or a sense of heat.
Many choose this formula for menopausal support, dryness, ageing, tinnitus, chronic fatigue, developmental delay, and other long-term patterns linked to Yin depletion. It suits those who want support when the body feels depleted, overheated, or less resilient rather than acutely unwell.
Why it stands out
What makes Nourish Root Yin so useful is its foundational role. It does not only target one symptom. It helps nourish deeper reserves that support moisture, balance, and recovery over time. This makes it a strong choice for natural support when dryness, fatigue, and age-related depletion begin to affect daily wellbeing.
Research
Research on Nourish Root Yin has shown encouraging results in metabolic balance, menopausal support, kidney health, and age-related cognitive function. Studies have reported better blood sugar and lipid markers, improved microbiota-gut-brain balance, and supportive effects in diabetic nephropathy. Research has also highlighted symptom relief in menopause and possible benefits in chemotherapy recovery, including appetite, white blood cells, and immune resilience. This gives Nourish Root Yin strong modern relevance and supports its traditional use when deeper depletion affects energy, dryness, ageing, and long-term recovery.
Important to know
Do not use Nourish Root Yin in high fever or alternating chills and fever. Because it is a rich formula, use it with caution in weak digestion, as it may cause loose stools.
