Pictures, Information, and Yield Estimates of
Medicinal Herbs Researched at NC State University

Studies have been conducted at six research stations in North Carolina to develop commercial production systems for medicinal herbs with potential economic value for North Carolina growers. We offer here some of the information gained from these studies. Please keep in mind that this is preliminary information and these are not recommendations. Yields are estimates from research plots and gross returns are based on prices found on-line at the site given. Some plants have not been established long enough to obtain yield data.

Estimated yields per acre are based on 109-4 x 100 ft beds/acre. Yield ranges may include 1-3 rows/bed.

Estimated gross returns are based on a list of medicinal herb prices provided by a U.S. manufacturer in fall, 2002. These are subject to change at any time.

Common Name: American Spikenard

Botanical Name: Aralia racemosa L.

Spikenard (Aralia racemosa) grows 1-10 feet tall and bears elongated flower stalks covered with yellow-green flowers which develop into purple berries. It grows in rich woods and riverbanks and is easy to cultivate. The roots are trditionally havested in the fall and used to treat many aliments, including backaches.

Common Name: Arnica

Botanical Name: Arnica chamissonis

Arnica flowers, leaves, and roots are used to make healing ointments to relieve pain and inflammation. Arnica is esily cultivated in a n open field setting. Arnica is currently being grown on black plastic, white plastic, and bareground in the upper piedmont of North Carolina and on white plastic in the coastal plains of North Carolina.

Common Name: Bloodroot

Botanical Name: Sanguinaria canadensis L.

Bloodroot is an attractive, low-growing plant with lobed, waxy leaves which puts on pretty white flowers in very early spring. It can often be found growing in deep woods. It spreads naturally by rhizomes and seeds and can be easily propagated by both. The root of the bloodroot, which "bleeds" when cut, has a long history of use by Native Americans and has proven antimicrobial activities. It can be toxic, however, and should not be used casually.
Bloodroot is currently in demand because of its use in an animal feed product that is manufactured in Germany and sold in Europe. We have several studies on-going in western North Carolina on the propagation and cultivation of bloodroot. Results from these studies will be available starting in spring 2004.

Common Name: Black Cohosh, Cohosh, Bugbane

Botanical Name: Actaea racemosa (L.) Nutt.

Black cohosh is a common, but very popular, woman's herb used in menopause and childbirth. Its immense popularity has caused concern for its well being and cultivation is encouraged. Fortunately, it is easy to cultivate. It is an attractive shrub, which can grow quite tall, with delicate, lacy-type foliage. It thrives in rich, moist soil in about 80% shade. The roots are harvested in early fall for medicinal use. It can be propagated by dividing the rhizomes in spring or fall. Seed propagation is difficult, but we have a graduate student currently working on this problem.

Common Name: Blue Cohosh

Botanical Name: Caulophyllum thalictroides (L.) Michx

Blue Cohosh is another beautiful plant that is commonly found in hardwood forests in southern Appalachia. The plant grows to about 3 feet in height and early in the year can have very blue foliage. In spring it puts on yellowish-green flowers which develop into a cluster of blue-purple berries. The rhizomes can be divided in spring or fall and the plant will spread naturally. Seeds are difficult and slow to germinate and should be kept moist. Blue cohosh is another woman's herb, the root of which was traditionally used as a childbirth aid. It is easy to grow but the market is small.
