Liu Wei Di Huang Wan (Six Ingredient Pill with Rehmannia)

Actions

Indications

Western Uses:

• What conditions is Liu Wei Di Huang Wan used for in modern practice?

  Liu Wei Di Huang Wan is the foundational Kidney-and-Liver yin tonic (dizziness, tinnitus, sore weak lower back, night sweats, heat in the "five centres"), so it is referenced very broadly across yin-deficiency presentations: delayed growth in children, low back pain (lumbago), optic neuritis, central retinitis, pulmonary tuberculosis, diabetes, hyperthyroidism, Addison's disease, hypertension, nervous exhaustion (neurasthenia), functional anovulatory uterine bleeding, chronic urinary tract infections, and deafness.

  The unifying thread is the yin-deficiency pattern, not any single diagnosis. Tuberculosis (infectious and notifiable), diabetes, thyroid and adrenal disease, hypertension, and sight-threatening eye conditions (optic neuritis, retinitis) all require medical diagnosis and treatment; this classic tonic is a traditional adjunct, not a substitute. Traditional-use correlates only, not a treatment claim.

Notes:

• How does Liu Wei Di Huang Wan differ from Jin Gui Shen Qi Wan, You Gui Wan, and its own modifications?

  Liu Wei Di Huang Wan is the pure Kidney-yin half of a yin/yang pair — it is literally its parent formula, Jin Gui Shen Qi Wan, with the two warming herbs removed, and it is in turn the structural base for a large family of later modifications that add herbs to shift its emphasis.

  • vs Jin Gui Shen Qi Wan (its direct parent, in our database): Jin Gui Shen Qi Wan is Liu Wei Di Huang Wan plus Fu Zi (prepared aconite) and Gui Zhi (cinnamon twig), which warm and tonify Kidney yang alongside the yin tonics — used for Kidney-yang deficiency with cold signs (lower back/leg pain worse in cold, frequent clear urination, edema). Liu Wei Di Huang Wan keeps only the yin-nourishing half, for yin deficiency with empty heat rather than cold.
  • vs You Gui Wan (in our database): a much stronger Kidney-yang tonic built around Rou Gui, Fu Zi, and Lu Jiao Jiao with the yin tonics as support — for pronounced yang deficiency (cold limbs, impotence, infertility), the mirror-image use case to Liu Wei Di Huang Wan's pure yin deficiency.
  • vs Zuo Gui Yin (in our database): a gentler, purely yin-nourishing decoction without the “three drain” herbs (no Ze Xie, Mu Dan Pi, or Fu Ling) — used when yin deficiency is present without significant heat or dampness to drain.

  The Liu Wei Di Huang Wan modification family (well-known variants; not separately catalogued on this site) shows how flexible the six-herb base is:

  • Zhi Bai Di Huang Wan adds Zhi Mu and Huang Bai to drain more vigorous deficiency fire (night sweats, stronger heat signs).
  • Qi Ju Di Huang Wan adds Gou Qi Zi and Ju Hua to direct the formula toward the eyes (blurry vision, dry/sore eyes, photophobia from Liver/Kidney yin deficiency).
  • Mai Wei Di Huang Wan (also known as Ba Xian Chang Shou Wan, “Eight Immortal Longevity Pill”) adds Mai Men Dong and Wu Wei Zi to nourish Lung yin and astringe, for a chronic cough with Kidney-yin deficiency.
  • Du Qi Wan adds Wu Wei Zi alone, to astringe Kidney qi more strongly (e.g. for wheezing/asthma with a Kidney-deficient root).
  • Gui Shao Di Huang Wan adds Dang Gui and Bai Shao to strengthen the Liver-blood-nourishing side of the formula.

Clinical Studies & Research:

• Is there modern research on Liu Wei Di Huang Wan?

  Yes — Liu Wei Di Huang Wan (widely studied under its Chinese name, Liuwei Dihuang, abbreviated LWDH or LDP) is one of the most extensively researched classical formulas, with clinical trial data in diabetic kidney disease alongside a large body of preclinical work on aging, neuroprotection, and other conditions correlating loosely with its traditional Kidney/Liver-yin-deficiency indication.

  • Diabetic nephropathy (meta-analysis, clinical): a 2016 meta-analysis of 18 randomized controlled trials (1,275 patients) found that adding Liuwei Dihuang pills to standard Western treatment for diabetic nephropathy was associated with greater reductions in fasting and post-prandial blood glucose, HbA1c, and markers of kidney damage (BUN, serum creatinine, urinary protein) than Western treatment alone; the authors noted the included trials were of generally low methodological quality and called for more rigorous confirmation (PMID 26997962).
  • Longevity and stress resistance (preclinical, C. elegans and aged mice): a 2019 study found that Liuwei Dihuang extended lifespan in both the roundworm C. elegans and aged mice, associated with improved stress resistance and altered fat metabolism pathways — a modern angle on the formula's traditional reputation as a longevity/anti-aging tonic (PMID 31165002).
  • Parkinson's disease mechanisms (preclinical, network pharmacology): a 2021 network pharmacology analysis identified candidate active components of Liuwei Dihuang pills (including quercetin, kaempferol, stigmasterol, and beta-sitosterol) and predicted hub protein targets related to neuroinflammation and cell death pathways relevant to Parkinson's disease (PMID 34746302).
