Bu Zhong Yi Qi Tang: The Ultimate Formula for Chronic Fatigue
Updated March 2026 ยท 8 min read
Feeling exhausted no matter how much you sleep? Catching every cold that goes around? In Traditional Chinese Medicine, these are hallmarks of "sinking Qi" โ and Bu Zhong Yi Qi Tang has been the master formula for this pattern since the 13th century.
What Is Bu Zhong Yi Qi Tang?
Bu Zhong Yi Qi Tang (่กฅไธญ็ๆฐๆฑค), meaning "Tonify the Middle and Augment the Qi Decoction," was created by the legendary physician Li Dongyuan (ๆไธๅฃ, 1180โ1251 CE) in his groundbreaking text Pi Wei Lun (่พ่่ฎบ, Treatise on the Spleen and Stomach).
Li Dongyuan's revolutionary insight was that many chronic diseases stem from damage to the Spleen and Stomach โ the body's digestive engine. When the Spleen Qi becomes so weak that it "sinks," the body loses its ability to hold things up, both physically (organ prolapse) and energetically (chronic fatigue, depression).
Ingredients
- Huang Qi (้ป่ช) โ Astragalus: The chief herb, powerfully tonifies Qi and raises Yang
- Ren Shen (ไบบๅ) โ Ginseng: Strongly tonifies Spleen and Lung Qi
- Bai Zhu (็ฝๆฏ) โ Atractylodes: Strengthens the Spleen, dries dampness
- Zhi Gan Cao (็็่) โ Honey-fried Licorice: Tonifies Qi, harmonizes the formula
- Dang Gui (ๅฝๅฝ) โ Angelica: Nourishes Blood (Qi and Blood are inseparable)
- Chen Pi (้็ฎ) โ Tangerine peel: Moves Qi, prevents stagnation from the tonics
- Sheng Ma (ๅ้บป) โ Cimicifuga: Raises the Yang Qi upward
- Chai Hu (ๆด่ก) โ Bupleurum: Raises the Yang Qi, spreads Liver Qi
The genius of this formula lies in Sheng Ma and Chai Hu โ two "raising" herbs that lift the sunken Qi back to its proper position. Without them, the tonifying herbs would just add energy without direction.
Who Needs Bu Zhong Yi Qi Tang?
1. Chronic Fatigue
Not ordinary tiredness, but deep exhaustion that doesn't improve with rest. The person feels worse after exertion, speaks in a weak voice, and may feel dizzy when standing up. This is the formula's primary indication.
2. Weak Immunity
People who catch every cold, take weeks to recover from minor illnesses, or get recurrent infections. In TCM, the Wei Qi (defensive Qi) depends on strong Spleen Qi. When the Spleen is weak, the body's defenses collapse.
3. Organ Prolapse
When Qi is too weak to hold organs in place: uterine prolapse, rectal prolapse, gastroptosis (stomach dropping), or chronic hemorrhoids. The "raising" herbs in this formula specifically address this sinking pattern.
4. Chronic Diarrhea
Long-term loose stools or diarrhea that worsens with fatigue or stress. The Spleen is too weak to transform food properly, and Qi is sinking downward instead of holding firm.
5. Post-Illness Recovery
After prolonged illness, surgery, or childbirth when the body's Qi reserves are depleted. Bu Zhong Yi Qi Tang rebuilds the foundation.
Dosage
- Patent pills (่กฅไธญ็ๆฐไธธ): 8-10 pills, 2-3 times daily
- Granules: 1 packet, 2-3 times daily
- Best time: 30 minutes before meals on an empty stomach
- Duration: 2-8 weeks depending on severity
Bu Zhong Yi Qi Tang vs Gui Pi Tang
- Bu Zhong Yi Qi Tang: For Qi sinking โ fatigue, prolapse, weak immunity. Focus is on RAISING Qi.
- Gui Pi Tang: For Heart-Spleen deficiency โ insomnia, anxiety, poor memory. Focus is on NOURISHING Blood and calming the mind.
Both treat Spleen Qi deficiency, but from different angles.
Who Should Avoid It?
- People with Yin deficiency and Heat signs (night sweats, hot flashes)
- During acute infections with fever
- People with high blood pressure (the raising herbs may worsen it)
- Those with excess patterns (strong constitution, loud voice, red face)
