Case Report of Refractory Psoriatic Arthritis Achieving Remission Using<i>Nigella sativa</i>(Black Seed Oil) Extract
Bibliographic record
Abstract
To the Editor: Psoriatic arthritis (PsA) is one of the major extra skin manifestations of psoriasis and will develop in 20–30% of patients with psoriasis1. Alternative medicines, mainly herbal products, have been commonly used by patients for the treatment of psoriasis and there have been some studies into their efficacy, but most cases of PsA still require systemic therapy2. Extract from Nigella sativa , also known as black seed oil, has been found to have antiproliferative, antiosteoporotic, antiinflammatory, and antidiabetic effects in many studies3. The major active ingredient, thymoquinone, has been demonstrated to have comparable results with topical hydrocortisone 2.5% when applied topically on carrageenan-induced paw edema and granuloma pouch on rats, manifested by a notable decrease in leukocyte count and tumor necrosis factor-α concentration in inflamed … Address correspondence to Dr. D.D.

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.
