Abstract
The effects of the ethanolic extracts of 105 plants used in Russian traditional medicine, 26 vegetables and fruits and 2 mushrooms on the release of tumor necrosis factor α (TNF-α) and prostaglandin E2 (PGE2) in lipopolysaccharide (LPS)-stimulated differentiated human acute monocytic leukemia THP-1 cells were studied using TNF-α and PGE2 assays, respectively. We found that 16 plant extracts inhibited TNF-α production and 15 extracts decreased PGE2 release in the cells in a concentration-dependent manner. Guilder rose, tansy, shrubby cinquefoil, wintergreen, and prince’s pine, the last two of which belong to the Pyrolaceae family, notably inhibited the levels of both of the inflammatory mediators.
