- Comprehensive contaminant screening and microbial safety evaluation of a classical Unani anti-arthritic formulation (2026) · Discover Chemistry · doi
The safety screening in the present study was confined to four WHO-recommended contaminant categories; heavy metals, aflatoxins, pesticide residues, and microbial load; representing the most clinically relevant parameters for herbal drug safety evaluation; other potential impurities may be explored in future work as part of comprehensive standardization efforts. Multi-batch evaluation across different procurement cycles would further strengthen the generalizability of these findings. Razi et al.

Herbal supplements are often regarded as “natural”, and are, therefore, considered by many to be safer than pharmaceuticals; however, the adverse effects of these supplements are under-reported in many cases.
