# Plant Extract Mixture Shows Promise in Laboratory Psoriasis Model A recent laboratory study found that a **plant extract mixture containing apple, curly kale, and green tea** demonstrated three beneficial effects in a simplified psoriasis skin model: it strengthened the skin barrier, reduced inflammatory markers, and acted as an antioxidant. ## What the study examined The researchers used a 2D laboratory model of psoriatic skin to test whether this plant extract could address three core problems in psoriasis: inflammation, a weakened skin barrier, and oxidative stress. The extract activated a cellular receptor called the aryl hydrocarbon receptor (AhR), which helped restore filaggrin—a protein that holds your skin barrier together. ## What this means for you right now This is early-stage laboratory research. The study was conducted in a simplified skin model, not in human skin or human bodies. Before any topical treatment based on this extract could be developed, the findings would need to be confirmed in more complex models and eventually in clinical trials with people who have psoriasis. The results are encouraging because they suggest a natural approach could potentially target multiple pathways involved in psoriasis. However, it will take years of further research to determine whether this would be safe and effective as an actual treatment you could use at home. ## Next steps If you're interested in plant-based approaches now, speak with your dermatologist about options with existing evidence, such as topical preparations containing Oregon grape or aloe vera.
