AHPA's 1999 Herb Tonnage Survey: Summary and Analysis
by Michael McGuffin
The American Herbal Products Association (AHPA) recently
completed its second consecutive annual tonnage survey. This survey tabulated
harvest data for each of the three years from 1997 to 1999 for many of the most
widely traded wild and cultivated North American medicinal plants.
While the prior year's survey was concerned only with
goldenseal root (Hydrastis
canadensis), the new survey includes
goldenseal leaf, as well as
American ginseng root (Panax quinquefolius); black cohosh root (Actaea racemosa syn. Cimicifuga racemosa); cascara sagrada bark (Frangula purshiana
syn. Rhamnus purshiana); osha root (Ligusticum porteri); saw palmetto berry (Serenoa repens); slippery elm bark (Ulmus rubra); and wild yam root (Dioscorea villosa). In addition, both root and "herb" (defined as "any
and all aboveground parts") are quantified for three species of Echinacea.
The tonnage survey shows a uniform three-year pattern for several
high volume herbs, wherein increases from 1997 to 1998 were followed by
declines in total harvest from 1998 to 1999. The herbs for which this pattern
emerged included black cohosh root, saw palmetto berry, goldenseal root, and
almost all root and herb commodities in the genus Echinacea.
How does one explain this consistency over such a variety of
plants? One place to look is toward recent market factors. Each of these plants
enjoyed significant increases in product placement toward the beginning of this
three-year period, so that the 1998 harvest for these came on the heels of
large increases in the number of herbal products containing these herbs. As a
result, that year's harvest was planned when raw materials had been depleted
and buyer confidence suggested the new product "boom" would continue. The
anticipated increase in consumer demand for these products failed to meet such
an aggressive increase in supply however, and the 1999 harvest fell to former
levels and below.
Entirely different factors affected the market for wild
American ginseng, as the primarily Asian market for this botanical has reduced
its demand because of regional financial difficulties. The three-year record
for wild American ginseng appears to reflect the Asian economy, so that the
harvest in each of the past two years, while consistent at about 11.5-12 short
tons (2000 pounds), is significantly less than the 1997 harvest of 19.5 tons.
Annual harvests of the other surveyed wild harvested species
do not exhibit any common pattern. The 1999 data shows stable use of slippery
elm bark (between 93 and 132.5 tons in each of the past three years) and wild
yam root (between 29 and 31 tons each year). However, the use of cascara
sagrada bark spiked in 1998 at 176 tons, compared to 58 in 1997 and 134.5 in
1999. Use of osh‡ also increased to about 6.5 tons in both 1998 and 1999
compared to less than 1.25 tons in 1997.
With the exception of American ginseng, goldenseal and most
echinacea species, only modest agricultural production was reported for any of
the botanicals surveyed. Reported cultivation of osh‡ was measured at
approximately 0.5 ton in 1998 and 1 ton in 1999. Although more than 17.5 tons
of black cohosh came from cultivated sources in 1998, this amount fell to less
than 1.5 tons in 1999. Finally, although significant harvest of cultivated saw
palmetto was reported, this may be more accurately described as managed
populations of wild saw palmetto rather than cultivated crops; a fine point of
definition.
On the other hand, the 1999 harvest of more than 23.5 tons
of cultivated dried goldenseal root represented more than a seven-fold increase
from 1998. The proportion of the total harvest from agricultural efforts thus
increased from only 2 percent in 1998 to 34 percent in 1999. In addition, the
total goldenseal acreage under cultivation was stable in each of the past two
years, averaging between 140 and 145 acres.
The 1999 tonnage survey extends the quantitative usage data
gathered by the herb industry from only 1 botanical commodity in 1998 to 16 in
1999. Harvest decreases are recorded for certain species that may be due in
part to broad market factors. The cultivated portion of certain high volume
species such as goldenseal and all species of Echinacea are demonstrating increases. Other plants, such as
slippery elm and black cohosh, continue to rely almost exclusively on harvests
of wild populations.
The survey itself was administered by a third party, the
accounting firm of Arthur Anderson LLP, to assure responders of the
confidentiality of sensitive information. It was designed by AHPA staff and the
AHPA Botanical Raw Material Committee, and delivered to all active association
members and several non-member companies that cultivate or trade bulk raw
materials. Nineteen producers replied to the survey.

Survey was sponsored in part by the generous financial support of Nutritional Outlook magazine. The full
