Scientists discovered that extracts from the mushroom Inonotus rheades can fight cancer cells, and the way these mushrooms are grown affects how well they work. The researchers tested different growing conditions, including using different types of wood and exposing the mushrooms to blue light or darkness. This research is important for developing natural cancer treatments. Impacts on everyday life: • Provides a potential natural source for cancer treatment • Shows how growing conditions can improve medicinal mushroom properties • Demonstrates the importance of proper cultivation methods for medicinal fungi • Opens possibilities for sustainable production of natural medicines
