Pharmacological Screening: General Workflow

Pharmacological screening of a herbal candidate typically begins with a broad, low-resolution screen across multiple activity domains — antioxidant, antimicrobial, anti-inflammatory, and cytotoxic assays are commonly run in parallel on the same crude extract — in order to establish an overall bioactivity profile before resources are committed to a specific, mechanistically focused evaluation pathway. This broad initial screen is particularly valuable for herbal candidates because a single plant extract frequently demonstrates activity across several pharmacological domains simultaneously, reflecting both the multi-constituent nature of the extract and the polypharmacological character of many individual phytoconstituents; the specific assay platforms used within each activity domain are described in the sections that follow.
