Gastric Ulcer Healing
To evaluate raw cabbage juice for peptic ulcer healing.
Study Type
Clinical trial (Garnett Cheney's original study)
Purpose
To evaluate raw cabbage juice for peptic ulcer healing.
Dose
~1 L fresh cabbage juice daily (divided doses)
Participants
13 patients with confirmed peptic ulcers
Duration
7-10 days per patient
Results
Average healing time was 10.4 days with cabbage juice vs historical average of 37 days with standard therapy. All 13 patients showed complete healing.
How They Measured It
Radiographic ulcer healing, symptom resolution
To further evaluate cabbage juice for duodenal ulcer healing.
Study Type
Clinical trial
Purpose
To further evaluate cabbage juice for duodenal ulcer healing.
Dose
~1 L fresh cabbage juice daily
Participants
45 patients with gastric or duodenal ulcers
Duration
Average 13 days
Results
86% of ulcer patients showed complete healing. Average healing time was 13 days for gastric ulcers and 10 days for duodenal ulcers.
How They Measured It
Radiographic/endoscopic ulcer healing
To evaluate cabbage juice extract and S-methylmethionine on ethanol-induced gastric mucosal damage.
Study Type
Animal study
Purpose
To evaluate cabbage juice extract and S-methylmethionine on ethanol-induced gastric mucosal damage.
Dose
Cabbage juice extract (10 mL/kg)
Participants
40 Wistar rats with ethanol-induced gastric injury
Duration
Single dose pretreatment
Results
Cabbage juice extract significantly reduced gastric mucosal damage by 65%. S-methylmethionine (vitamin U) identified as key active component. Mucus secretion was increased.
How They Measured It
Gastric mucosal lesion area, histological damage scoring, mucus secretion
Anti-inflammatory & Antioxidant
To evaluate anti-inflammatory activity of cabbage juice extract.
Study Type
In vitro and animal study
Purpose
To evaluate anti-inflammatory activity of cabbage juice extract.
Dose
Various concentrations (in vitro); 10 mL/kg (in vivo)
Participants
Cell culture + 30 Wistar rats
Duration
In vitro + 7 days in vivo
Results
Cabbage juice extract significantly inhibited COX-2 expression and NF-κB activation. In vivo, paw edema was reduced by 45% comparable to indomethacin.
How They Measured It
COX-2 expression, NF-κB activation, paw edema model (in vivo)
To evaluate antioxidant properties of cabbage juice and identify active compounds.
Study Type
In vitro study
Purpose
To evaluate antioxidant properties of cabbage juice and identify active compounds.
Dose
Various concentrations of cabbage juice extracts
Participants
In vitro analysis
Duration
N/A
Results
Cabbage juice showed strong antioxidant activity correlated with glucosinolate and polyphenol content. Red and savoy cabbage varieties showed highest activity.
How They Measured It
ORAC, DPPH radical scavenging, identification of glucosinolates and phenolic compounds
H. pylori & Gastritis
To evaluate cabbage juice antimicrobial activity against H. pylori.
Study Type
In vitro study
Purpose
To evaluate cabbage juice antimicrobial activity against H. pylori.
Dose
Various concentrations of cabbage juice extract
Participants
In vitro (8 H. pylori strains)
Duration
N/A
Results
Cabbage juice showed bacteriostatic activity against H. pylori at concentrations achievable through oral consumption. Urease activity was inhibited by 60%.
How They Measured It
MIC determination, H. pylori growth inhibition, urease inhibition
To evaluate cabbage juice as adjunctive therapy for H. pylori gastritis.
Study Type
Clinical pilot study
Purpose
To evaluate cabbage juice as adjunctive therapy for H. pylori gastritis.
Dose
250 mL cabbage juice twice daily
Participants
18 H. pylori-positive patients with gastritis
Duration
4 weeks
Results
Cabbage juice as adjunct to standard triple therapy showed trend towards improved eradication rates and significantly faster symptom improvement.
How They Measured It
H. pylori status (urea breath test), gastritis symptom score
