Verdict No. 1990 · Search date 2026-08-02 · Methodology v0.6

Dried persimmon,
does it really help with Shorter acute diarrhea, fewer stools, or improved stool consistency?

30-Second Summary
?
Evidence Grade ? · Safety caution
Tannins and astringency are real, but effects of dried persimmon on acute diarrhea have not been measured in humans
Heavy persimmon intake can rarely form a diospyrobezoar and cause gastrointestinal obstruction. People with prior gastric surgery, diabetic gastroparesis, or impaired gastric motility should avoid excessive intake.
What the
research shows
The grade is ?. Persimmon tannins and astringency are real, but no human study was found that fed dried or whole persimmon and measured acute-diarrhea duration, stool frequency, or consistency. The antidiarrheal paper found by the search used an extract in rats.
What the
ads claim
A Korean folk remedy claiming that persimmon or dried persimmon stops diarrhea is genuinely circulated. Astringency alone does not establish shorter or less frequent diarrhea in people.

Useful facts when choosing a product

  • Astringent persimmons contain soluble tannins that interact with proteins and create an astringent sensation.
  • During deastringency, acetaldehyde forms and binds tannins, making them insoluble and reducing astringency. Dried persimmon is chemically different from astringent fresh fruit.
  • The antidiarrheal fruit-aqueous-extract paper used 60 male rats with castor-oil-induced diarrhea, not whole dried persimmon in humans.
  • Case reports document diospyrobezoars and intestinal obstruction after heavy persimmon intake.

What the research actually shows

On 2026-08-02, PubMed was searched for 「(persimmon OR Diospyros kaki OR dried persimmon OR gotgam) AND (diarrhea OR antidiarrheal OR stool frequency OR stool consistency)」. One antidiarrheal result was screened and proved to be a rat study of aqueous fruit extract. Searches of the Cochrane Library and ClinicalTrials.gov with the same concepts found zero eligible human or registered trials of dried or whole persimmon; laboratory, animal, leaf, calyx, and extract studies were excluded as different interventions.

02

Why this is classified as ?

No human study directly fed dried or whole persimmon and measured acute-diarrhea outcomes. The repeated search found zero eligible studies, so the grade is ? with no score.

Counterpoint. Tannins and astringency are established, but clinical effects of dried persimmon on acute diarrhea remain unmeasured.

Rejudgment record. Cross-check applied — PubMed, Cochrane Library, and ClinicalTrials.gov searches found no human study of acute-diarrhea outcomes after dried or whole persimmon

Sub-claim grades by effect

This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.

Persimmon contains tannins and is astringent?This is an established chemical and sensory fact, not a graded clinical endpoint.
Dried persimmon relieves acute diarrhea?No direct human trial exists.

Cross-check — Codex and Claude

This verdict was drafted by Codex through literature review and source-existence checks, cross-checked through blind grading and adversarial audit, and settled by reapplying the methodology boundary rules. Cases with split grades were resolved through rejudgment.
