Safety Overview
1.Water Mint — Overview
Water Mint (Mentha aquatica) is a captivating perennial herb, typically growing 30 to 100 cm in height, characterized by its robust, often hairy, square stems—a feature that helps distinguish it from other mint species. Its leaves are ovate to lanceolate, measuring 4 to 8 cm in length, with a smooth edge and a rich green hue accented by darker veins, contributing to their appealing appearance.
When crushed, these leaves release a distinctly refreshing mint aroma, making the plant desirable for both culinary and medicinal applications. Small, tubular flowers, ranging from pale lilac to pink, form dense clusters that bloom from mid to late summer, actively attracting a diverse array of pollinators such as bees and butterflies.
This species thrives in consistently moist to wet environments, commonly found in marshes, along riverbanks, and beside ponds across Europe, Asia, and parts of North America. As a member of the Lamiaceae family and the Mentha genus, Water Mint shares aromatic and therapeutic qualities with its relatives. It prefers rich, damp soil and can tolerate partial shade, though it reaches its full potential in full sun.
The stems often feel sticky to the touch due to surface oils, and the plant spreads vigorously through rhizomes, forming lush growth in suitable conditions. The entire plant, especially its aerial parts during the flowering phase when the aroma is most potent, is harvested for its valuable essential oils.
