Immature Bitter Orange
枳实 · zhǐ shí
Breaks stuck qi in the gut for bloating and constipation
What it does
When food piles up in your gut and nothing moves, zhi shi kicks it loose. In TCM, it breaks up stuck qi, the energy that moves through your body, clearing bloating, constipation, and heaviness after a big meal. The immature fruit works lower and harder than mature bitter orange, targeting the abdomen. Practitioners also use it with tonifying herbs to lift prolapsed organs.
Safety
- Use with caution during pregnancy. Strongly descends and moves qi.
- Not for Spleen and Stomach deficiency without accumulation; dispersing where nothing is stuck depletes qi.
- Contains synephrine; avoid concentrated extracts if you have heart problems or take stimulants.
- Bitter orange furocoumarins may inhibit CYP3A4 and affect medications processed by this enzyme pathway.
How to take it
Decoct 3-9g of dried immature bitter orange in 4 cups water for 30 minutes. Often combined with magnolia bark, rhubarb, or other digestive herbs. Not typically taken alone.
Best used as part of a formula for digestive qi stagnation or abdominal fullness

Where it comes from
Zhi shi and its near-ripe cousin zhi ke represent one of TCM's classic debates about precision dosing. Wang Hao-Gu's 13th-century dictum guides clinicians still: 'zhi ke governs the heights, zhi shi governs below.' The immature fruit's stronger bitter, downward-draining nature made it standard for constipation and abdominal fullness; the nearly ripe fruit's gentler action suited the chest. Today the herb also appears in modern research on prolapsed organs and gastrectasis.
