Lélastine
Lelastine is a fictional plant described in the novel "The Name of the Wind" by Patrick Rothfuss. It is depicted as a rare and elusive flower with a striking sapphire-blue color. The plant is said to grow in remote and challenging environments, often found in high altitudes or dense, ancient forests. Its petals are described as being velvety to the touch and possessing a unique luminescence, appearing to glow faintly in low light conditions. Lelastine is highly sought after for its medicinal properties, particularly its ability to aid in the healing of wounds and its rumored efficacy in warding off certain ailments. Alchemists and apothecaries value it greatly, and its rarity contributes to its high price and the difficulty in acquiring it. The flower's delicate nature means it wilts quickly once picked, further complicating its use and trade. In the narrative, the search for lelastine is often a perilous undertaking, requiring significant skill and knowledge of the wilderness.
