Safety Overview
1.Reseda — Plant Snapshot
Reseda luteola, commonly known as weld or dyer's rocket, is a remarkable herbaceous biennial plant thriving in temperate to subtropical regions, typically reaching heights of 40 to 80 centimeters, though it can extend up to a meter in optimal conditions. Its erect, smooth, and often branched stems support distinctive, narrow, elongated leaves that are lanceolate to ovate, measuring up to 15 centimeters in length, and presenting a vibrant bright green hue. The plant's striking inflorescence, blooming from July to September, consists of densely clustered, small, pale yellow to greenish-yellow flowers, each measuring approximately 4 to 6 millimeters in diameter.
Reseda luteola exhibits a slightly rough texture near its base. This species flourishes in sunny environments and is frequently encountered on disturbed soils, roadsides, and open fields across Europe, parts of Asia, and has been naturalized in other regions. Belonging to the family Resedaceae, it holds significant historical importance, particularly for its potent luteolin-based dye, alongside a rich tradition of medicinal application.
Its cultivation is believed to have originated in the Mediterranean basin, facilitating its widespread adoption into various traditional medicine systems globally, notably in Ayurvedic practices. Beyond its human uses, Reseda luteola plays a vital ecological role by supporting diverse pollinator populations during its extended flowering season.
