Regulation of Wild American Ginseng Harvest and Sale

Andy Hankins, Extension Specialist-Alternative Agriculture, Virginia State University


In August of 2005, the Fish and Wildlife Service of the United States Department of the Interior enacted a new regulation that affects persons who dig wild ginseng roots and for persons who buy wild ginseng roots in Virginia. The new law requires wild roots of American ginseng, Panax quinquefolius, to be 10 years of age or older to be exported from Virginia. To be certified for sale there must be 9 or more bud-scale scars on the neck of the rhizome. This new regulation applies to nineteen states in the Mid-Atlantic and the North Central regions of the United States.

Interested persons read this regulation on the Internet at the following url:http://www.fws.gov/international/pdf/2005ginsengfinding.pdf

Digging ginseng has been a pleasant and profitable pastime for many generations throughout the entire Appalachian Chain from Maine to Georgia. However there are reports that this law is already causing a great deal of disruption in the trade of wild harvested ginseng roots. Although wild ginseng plants are scarce in certain regions due to over-harvest and loss of habitat, in other regions there are healthy, thriving populations. Ginseng diggers who live in those areas where wild ginseng plants are plentiful are understandably angry about this new law. Selling dried ginseng roots has been a reliable source of supplemental income for many people in the mountain regions of Virginia. This activity, which is especially prevalent in Southwest Virginia, creates about $1.2 million in annual income, through sales of approximately 4000 lbs. of root each year. With the new regulation, this amount of harvest and sales is anticipated fall by at least fifty percent.

The U. S. Fish and Wildlife Service regulation advises everyone to "dig mature four leaf ginseng plants" to assure that the roots are at least 10 years old. However, throughout much of ginseng's range, 4 leafed plants are extremely rare regardless of their age. Only plants growing on very good sites routinely produce 4 leafed plants and often they do so before age 10. All knowledgeable ginseng researchers are aware of this fact, as well as dealers and diggers all across the range of ginseng.
All of the very old wild ginseng roots in this photograph were two prong plants. This forest was decimated by forest tent caterpillars two years ago and again last year which caused the ginseng to senesce early (it gets sunburned). The result of this is small tops on big, old roots. Photo courtesy of Bob Beyfuss - Cornell Cooperative Extension.

The new Fish and Wildlife Service regulation states "Please, be advised that, based on our analysis of available information, we find that the export of wild American ginseng roots from plants 10 years of age (4-leafed) or older (i.e., with 10 or more bud-scale scars on the rhizome) harvested during the 2005 season in the following States will not be detrimental to the survival of the species: Alabama, Arkansas, Georgia, Illinois, Indiana, Iowa, Kentucky, Maryland, Minnesota, Missouri, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia, and Wisconsin."
These two prong ginseng plants are about 25 years old. Although ginseng plants tend to get larger as they grow older, there is no assurance that 4 leafed plants are at least 10 years old or that 2 or 3 leafed plants are less than 10 years old.

Another statement in the new Fish and Wildlife Service regulation is: "The export of wild-simulated and woods-grown ginseng that is younger than 10 years of age, which is treated as wild for CITES export purposes, may be authorized on a case-by-case basis if applicants are able to document the origin their roots (including source of seed or transplants)." This language has created a fortunate loophole in a very unfortunate regulation, which results in persons who plant purchased seed or roots to create a naturalized stand of American ginseng on privately owned land, are not being subject to the U. S. Fish and Wildlife regulations.

Thus privately-owned and grown ginseng may be harvested at any age and sold to buyers anywhere, without any kind of permits or certification, provided the grower can prove they cultivated it. Growers just have to keep receipts that prove that they purchased the seed or transplants, and they should keep records showing the planting dates and harvest dates. Forest landowners who might like to try growing ginseng are directed to Virginia Cooperative Extension Publication 354-312 Producing and Marketing Wild Simulated Ginseng in Forest and Agroforestry Systems by Andy Hankins. This publication can be read on the Internet at the following url: http://pubs.ext.vt.edu/354-312/

This new law enacted by the U. S. Fish and Wildlife Service will certainly reduce the available supply of wild ginseng roots that international buyers and domestic buyers can purchase this fall and for many years to come. No one knows for sure but several industry leaders are predicting that prices paid for wild ginseng roots will rise. Persons in a secure location, who own forested land, may want to take advantage of this new law by buying and planting ginseng seeds in November of 2005.

Laetiporus Sulphureus: A Medicinal Mushroom from Ethiopia

February 27, 2013

Penn State Food Science visiting scholar Ashagrie Zewdu will present "Laetiporus sulphureus: a Medicinal Mushroom from Ethiopia" from noon to 1 p.m. on Wednesday, March 13, in Foster Auditorium, first floor, Paterno Library on the University Park campus of Penn State. Zewdu, a doctoral candidate in the Center for Food Science and Nutrition, Addis Ababa University, Ethiopia, will describe a study conducted by the Huck Institute of Life Sciences at Penn State, which examined the properties of Laetiporus sulphureus.

Describing the presentation, Zewdu said, "Fungi have yielded some of the most widely sold products in the pharmaceutical marketplace including antibiotics, immunosuppressives and cholesterol-lowering agents. Additionally, some fungi, such as the ergot fungus (LSD) and psilocybin (magic) mushroom produce hallucinogens that are used ceremonially in traditional cultures and recreationally in contemporary societies.

"Wild mushrooms are used as both food and medicine by various ethnic groups in Ethiopia. The Kaffa people in southwest Ethiopia use the fruiting body of Laetiporus sulphureus to relieve stomach pain and to expel a woman's retained placenta following childbirth. However, no clinical studies have been conducted to validate the medical claims ascribed to this mushroom and no chemical compound contained in the mushroom has been identified as a possible agent responsible for the mushroom's metabolic effects."

The Huck Institute of Life Sciences comparative metabolomic (metabolite profiling) study of Laetiporus sulphureus was conducted on the basis of ethnomycological information obtained from the Kaffa. The goal of the study was to identify the therapeutic compound unique to this mushroom. Enoxolone (glycyrrhetinic acid) was found to be the compound unique to Laetiporus sulphureus. Enoxolone is the compound responsible for the antiviral, anti-inflammatory and antioxidant properties of licorice. 

The event is free and open to the public and also can be viewed live online at: http://live.libraries.psu.edu and search for the presentation date in the menu to bring up the direct link. (No log in is required.) It is part of an ongoing series highlighting the importance of indigenous knowledge and is sponsored by ICIK, the Interinstitutional Consortium on Indigenous Knowledge, and the Penn State Social Sciences Library.
