Too few graded studies
ASU doesn't have enough studies with structured effect-size data yet to pool a verdict. Browse the studies below for individual findings.
Most evidence is from high-quality meta-analyses and randomised trials published 1997–2025 with a typical study size of 5,980 participants.

In plain English: Evidence for the proprietary ASU product Piasclidine® in the treatment of osteoarthritis symptoms seems moderate to high for short term use, but studies over a longer term and against an apparently active control are less convincing.

Seventeen studies of confirmatory design (sample and effect sizes pre-specified) were mostly at moderate risk of bias.
Physical function was 33 points on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) 0 to 100 point subscale (0 is no loss of function) with placebo, enriched Boswellia serrata improved function by 8 points (95% CI 2 to 14); NNTB 4.
Moderate-quality evidence (one study, 96 participants) indicated that adverse events were probably reduced with enriched Boswellia serrata (18/48 events versus 30/48 events with placebo; relative risk (RR) 0.60, 95% CI 0.39 to 0.92).
In plain English: Despite some discrepancies regarding structural changes in the joints, clinical trials typically demonstrate symptom relief and slow down the disease progression.

Although results vary, pre-clinical research in different animal models has demonstrated positive effects, such as ameliorating histopathological changes and reduced inflammation.
Despite some discrepancies regarding structural changes in the joints, clinical trials typically demonstrate symptom relief and slow down the disease progression.
While ASU demonstrates significant promise in alleviating OA symptoms and reducing reliance on NSAIDs, further research is essential to fully understand its mechanisms of action.
