Gui Pi Tang (Restore the Spleen Decoction)

• What conditions is Gui Pi Tang used for in modern practice?

  Gui Pi Tang tonifies Spleen qi and Heart blood together — the "overthinking, worry and exhaustion" pattern with palpitations, poor sleep, poor memory and easy bleeding — so it is referenced across a wide deficiency spectrum: nervous exhaustion (neurasthenia), psycho-emotional disorders, post-concussion syndrome, myasthenia gravis, congestive heart disease, supraventricular tachycardia, anaemia, thrombocytopenic or allergic purpura, cervicitis, and functional uterine bleeding.

  The thread is the Spleen-qi-and-Heart-blood deficiency pattern, not any one diagnosis. Heart disease, arrhythmia, the anaemias, and purpura (a bleeding/platelet disorder) all require medical diagnosis and management; this formula is a traditional adjunct to that care, not a replacement. Traditional-use correlates only, not a treatment claim.

• Formulas to Aid the Living (Ji Sheng Fang)

Notes:

• How does Gui Pi Tang differ from Suan Zao Ren Tang and Tian Wang Bu Xin Dan?

  All three formulas treat deficiency-type insomnia and anxiety, but they target different roots: Gui Pi Tang addresses combined Heart-Spleen Qi and Blood deficiency with cold/deficiency signs, Suan Zao Ren Tang addresses Liver Blood deficiency with mild deficiency heat, and Tian Wang Bu Xin Dan addresses Heart-Kidney Yin deficiency with more pronounced empty heat.

  • Vs. Suan Zao Ren Tang: Suan Zao Ren Tang is a much smaller, gentler formula (five herbs) centered on nourishing Liver Blood and clearing mild deficiency heat — indicated for irritability, night sweats, and a wiry-thin, slightly rapid pulse. It carries no Spleen-Qi-tonifying core and does not address bleeding or marked fatigue/poor appetite the way Gui Pi Tang does.
  • Vs. Tian Wang Bu Xin Dan: Tian Wang Bu Xin Dan nourishes Heart and Kidney Yin with cooling herbs (e.g., Sheng Di Huang, Mai Men Dong, Tian Men Dong) for a presentation with a red tongue and thin, rapid pulse — true empty-heat signs. Gui Pi Tang instead uses warm Qi and Blood tonics for a pale tongue and thin, weak pulse, with fatigue and poor appetite prominent rather than heat signs.
  • Unique to Gui Pi Tang: the Spleen-not-controlling-Blood indication (easy bruising, blood in the stool, prolonged or irregular uterine bleeding) is not part of either comparison formula's traditional use.

  What is the classical source of Gui Pi Tang and how has it changed over time?

  Gui Pi Tang originates in the Song-dynasty formulary Ji Sheng Fang ("Formulas to Aid the Living," Yan Yonghe, 1253) as an eight-herb formula without Dang Gui or Yuan Zhi; the Ming-dynasty physician Xue Ji added both herbs (in Nei Ke Zhai Yao) to produce the version used today. A well-known later modification, Jia Wei Gui Pi Tang ("Gui Pi Tang Plus"), adds Chai Hu and Zhi Zi for the same Heart-Spleen deficiency pattern complicated by mild Liver constraint or heat signs such as irritability and a bitter taste; this modified formula is known in Korea and Japan as Kami Guibi-tang / Kami-kihi-to and is the version most often studied in recent East Asian clinical trials — findings from it should not be read as data on unmodified Gui Pi Tang.

Clinical Studies & Research:

• Is there modern research on Gui Pi Tang?

  Laboratory research on unmodified Gui Pi Tang has examined antidepressant-related mechanisms in stress-model animals, while most human clinical trials in the literature actually studied Jia Wei Gui Pi Tang / Kami Guibi-tang, a modified variant with Chai Hu and Zhi Zi added — a distinction worth keeping in mind when reading the evidence. This research is cited as scientific context for a traditional formula, not as a treatment claim.

  • A 2022 laboratory study using a chronic unpredictable mild stress rat model found that Guipi Tang reduced depression-like behavior and hippocampal cell apoptosis, associating this with upregulation of PI3K/Akt and BDNF/TrkB/CREB signaling components (PMID 36536902).
  • A registered pilot randomized, placebo-controlled, double-blind trial protocol examined Kami Guibi-tang — a modified Gui Pi Tang formula used in Korean medicine — for amnestic mild cognitive impairment, reflecting the formula family's traditional use for memory and cognitive complaints (PMID 31331367).
