Plant Description
Threeleaf goldthread is a small low-growing, perennial evergreen plant that normally grows about 5–6 ft. tall. The plant is found growing in wet to mesic, coniferous and mixed forests, bogs, willow scrub, and tundra. The plant has slender and hairless stem. The plant has attractive, glossy evergreen leaves that are 1-2 inches wide and appear at the end of a stem which is usually shorter than the flower stem. The leaves are compound, divided into three scalloped leaflets. The leaflets are fan-shaped, with small teeth around the tip end. Goldthread’s leaves uncoil every spring like a fern, as they replace the old evergreen leaves of the previous year.
Flower
Threeleaf Goldthread bears a solitary, small white flower on a long, slender, leafless stem. Each flower is ⅜ to ½ inch across and has four to seven petal-like sepals and many white stamens. The bright green styles are curled at the tip. The golden yellow club-shaped petals are shorter than the stamens and have a cup-shaped tip that holds nectar. Most plants have only one flowering stem. Flowering normally takes place from May.
Fruit
Fertile flowers are followed by an array of four to seven pods, each about 1/3 inches long. The capsule-like fruit changes from green to tan or light brown and splits open to expose the seeds.

To mention a few: dropsy, neuralgia, lumbago, gout, rheumatism and joint stiffness caused by uric acid deposits.
