RESULTS AND FUTURE PERSPECTIVES Organic and sustainable agricultureprinciples could be applied to fireweed cultivation, thanks to precision agriculture method and biodiversity (which is synergic with Epilobium angustifolium L. cultivation). Fireweed could be an important plant for honey industry: thanks to precision agriculture approach, next year also bee health status will be monitored. Data collection and processing will be very important to understand how fireweed pollen interacts with bees. Due to population ageing in Western countries, the market of prostatitis and BPH food supplements is increasing every year. Most of products are based on phytosterols coming from exotic plants as Serenoa repens fruits and Pygeum africanum bark. The last plant belongs to C.I.T.E.S. list, annex B (Convention on International Trade in Endangered Species). Since the demanding for natural remedies for this application is growing, it will be better to focus on local European plants that can be cultivated respecting the environment, facilitating the entomophilous insects’ health and producing functional ingredients with a rigorous scientific background.
