In the natural ecosystem, dog mercury plays a vital role in providing shelter and food for various insects and small mammals. Additionally, it helps in preventing soil erosion due to its spreading rhizome and forms an important part of the understory vegetation in woodlands and hedgerows.
Overall, dog mercury is a perennial herb with toxic properties, characterized by dark green leaves and inconspicuous flowers. It plays a significant role in ecological systems, but caution must be exercised due to its toxicity.
