Whole-eggplant powder,
does it really help with Reduction of office blood pressure?
research showsThe grade is C with 50 points. One hundred adults were randomized, 87 completed the study, and efficacy analyses included 36 eggplant and 41 placebo participants. The registered main endpoint of office diastolic pressure at week 8 had a between-group P=0.024, and conversion from the test statistic gave a conventionally medium-sized effect. Many favorable findings still came from a 24-person mild-hypertension subgroup.
ads claimThe powder's food equivalence and acetylcholine content can be measured directly, but they do not guarantee lower blood pressure. The paper did not directly report effect size; conversion from its test statistic was conventionally medium, while no between-group confidence interval was provided.
Useful facts when choosing a product
- The daily 1.2-g powder equaled about 22 g of fresh eggplant and supplied 2.3 mg acetylcholine.
- Eggplant is an Old World crop with longstanding East Asian documentation, but no classical text was checked for this verdict.
- NARO supported the trial, and one coauthor was affiliated with ADEKA; the paper declared no conflict of interest.
What the research actually shows
One hundred adults were randomized 50 per group, 87 completed the trial, and efficacy analyses included 36 eggplant and 41 placebo participants. The intervention was 1.2 g daily of juice-dried whole-eggplant powder for 12 weeks. The NARO agricultural technology program funded the work. One coauthor was affiliated with ADEKA, while the paper declared no conflict of interest.
Why this is classified as C (50)
The registered main endpoint converted to a conventionally medium effect, but only 77 of 100 randomized participants were analyzed, many favorable findings came from a 24-person subgroup, and blood pressure was a surrogate. This yields C with 50 points.
Counterpoint. A complete numerical table with direct repeated-measures estimates and confidence intervals would refine the converted magnitude and establish its precision.
Rejudgment record. Cross-check applied — Surrogate blood-pressure outcome, 77-person completer analysis, subgroup dependence, and a conventionally medium converted effect
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
| Precision | CX | No pooled confidence interval could be confirmed |
The scoring table and the verdict agree (C).
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.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Office blood-pressure reduction with whole-eggplant powder | C | The converted effect was conventionally medium, but the small completer analysis and subgroup dependence remained. |

| Study | Design | Sample | Funding | Endpoint | Result | Weight |
|---|---|---|---|---|---|---|
| Study 1 | Double-blind placebo-controlled 12-week randomized trial | 77 | NARO agricultural technology program; one ADEKA-affiliated coauthor | Office systolic and diastolic blood pressure | Overall DBP at week 8 P=0.024, t about 2.30, d about 0.525, g about 0.520; exploratory SBP at week 12 P=0.046, d about 0.464; between-group CI not reported | Converted registered-endpoint effect was conventionally medium but subgroup-dependent |
