Garcinia mangostana hydrogel patch
Bibliographic record
Abstract
Background and purpose Garcinia mangostana , simply known as mangosteen, has long been used by Thai traditional medicine because of its reported antibacterial and anti-inflammatory activities for the treatment of skin infections. In this study, mangosteen pericarps were developed into a hydrogel patch to eradicate acne-inducing bacteria. Experimental procedure: The G. mangostana extract was investigated for bactericidal activity. A hydrogel patch containing the extract was examined for mechanical properties, antibacterial activity, in vitro release, skin permeation, and a phase I clinical study of skin irritation and allergic testing by a closed patch test. Finding/Results: The G. mangostana hydrogel patch made from carrageenan and locust bean gum powders was yellow in color, smooth, durable, and flexible. This G. mangostana hydrogel patch was effective against Cutibacterium acnes, Staphylococcus epidermidis , and Staphylococcus aureus . The active ingredient, α-mangostin, was released and permeated from the G. mangostana hydrogel patch within the first 30 min at 33.16 ± 0.81% and 32.96± 0.97%, respectively. The G. mangostana hydrogel patch showed no irritation in 30 healthy volunteers. However, two volunteers had delayed allergic contact dermatitis to 0.5% (w/w) G. mangostana hydrogel patch. Conclusion and implication: This hydrogel patch containing G. mangostana ethanolic extract is not recommended for patients who have any reaction to mangosteen but has utility as an anti-acne facial mask.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
