Your query appears incomplete—it begins with a title and abstract excerpt but doesn't ask a specific question. However, based on the search results provided, I can offer key information about medicinal plants as immunomodulators: **Medicinal plants contain compounds that help regulate immune function.**[1] Researchers have identified about 150 plants with immunomodulatory properties, with the **Asteraceae plant family** being the most studied.[1] *Echinacea purpurea* is particularly well-known for strengthening immune responses.[1][2] The active compounds in these plants include **polyphenols, terpenoids, and alkaloids**.[1][2] Some specific molecules like curcumin, quercetin, and resveratrol have entered clinical trials and are sold commercially.[1] These plants work by triggering immune cells like macrophages and dendritic cells to fight infections more effectively.[2] Studies show they can help with respiratory infections, viral diseases, and overall immune function.[2] For conditions like psoriasis or psoriasis arthritis where the immune system is overactive, these immunomodulators could theoretically help regulate problematic immune responses—though targeted research on these specific conditions would be needed to confirm effectiveness. **To provide a more complete answer, could you clarify what specific information you're seeking?** Are you interested in how these plants work, specific plant recommendations, or their potential application for particular conditions?
