I am pleased to share a final project research paper from a recent graduate of the 9 month “Foundations of Herbal Medicine” program. This student has chosen to remain anonymous but would like to publicly share the project.

Goldenseal (Hydrastis conadensis) derives its name from two Greek words that mean water and to accomplish. It is a North American perennial woodland herb with a yellow perennial rhizome. In the spring, a new cylindrical flowering, downward pointing hairy stem grows about 30 cm high. The flower contains no petals, instead is made up of many stamens surrounding the pistil, creating the white to rose color of the plant. The leaves are large (up to 30cm wide) and contain 5 lobes with prominent veins. By mid to late summer, a single red fruit, resembling a raspberry, emerges with 10 to 30 black seeds. The fruit, while possibly valued by wildlife, is considered inedible by humans. Its root-stock is horizontal, irregularly knotted and bright yellow and produces slender roots below, The root stock is often marked with scars from past flower stems.
Habitat and Growing Conditions
Goldenseal is native to eastern North America. It grows well in rich moist forests through out its natural range. Researchers wishing to cultivate Goldenseal suggest that it grows well in any soil except heavy clay or light sand. The largest populations grow in mesic woodlands (moderately moist, hardwood forest or by streams). Cultivators suggest the best success is found with a loam soil.
Long before Europeans came to North American, Native people used goldenseal for a number of conditions. According to Moerman (1998), the Cherokee are the best known for their use of the herb, but he also shows that the Iroquois and Micmac used the herb. All three used goldenseal for digestive and dermatological conditions, also for its antibiotic properties. Along the same lines, Ingrid Naiman (1999) states that the settlers learned many of their treatments from the Cherokee but also the Blackfoot, Crow and the Seminole.
Once settlers learned of the healing properties, their knowledge was communicated back to European countries. Goldenseal was first introduced to England in 1760 and it received official recognition, documented in medical papers after 1798. Specialists used Goldenseal as pastes for cancer lesions, as well as tinctures, and teas.
Increased interest commercially first appeared in 1850 and in 1905 The Department of Agriculture documents increased interest for medicinal purposes.
Due to over harvesting, Goldenseal is threatened. Elpel (2012) suggests substituting other plants with similar properties such as Xanthorhiza simplicissima or Coptis. In order to diffuse market impact on the wild crop, Sinclair and Catling ( 2001) suggest a move from wild crops to cultivated crops. They suggest that goldenseal can grow well in wide-ranging conditions, is a good plant in rotation with Ginseng, remains an environmentally friendly plant , is inexpensive to cultivate and requires low energy, land use or fertilizations.
