Nearing the most dangerous part ofthe voyage in the rocky Sunda Strait ofIndonesia, between Java and Sumatra,the Empress had the good luck to meetup with two China-trading Frenchships, which showed the Yankee greenhornsthe way. On August 24, 1784, theAmerican ship’s captain noted in his logthat he “had the honour of hoisting thefirst Continentol Flagg Ever Seen ormaid Euse of in those Seas.”Cantonese customs officials were atfirst confused by the newcomers, whodid not come bearing gifts. But the officialsnevertheless welcomed the “FloweryFlag Devils” (the stars on their flagwere mistaken for flowers), most likelybecause the Empress contained so manycasks of the fabled root. When the shipreturned to the port of New York Citythat spring, she repaid her investorswith a handsome 25 percent profit.
Even Daniel Boone got into the ginsengtrade. In the winter of 1787 he senta bargeload of dried ginseng to marketin Philadelphia from his trading post inwhat is now central West Virginia. Onthe way, the vessel was swamped, andBoone’s ginseng ruined. Unfazed, hesent sangers back into the forest to collecta second bargeload.
In 1859, Minnesota’s Big Woods witnesseda ginseng rush. High prices forthe root helped many Minnesotansweather tough times brought on by aneconomic downturn two years earlier.In Mankato that year, a local paper reportedthat a ginseng dance wasplanned to make diggers “oblivious tomusquito bite or toil of delving for thebulbous root, whilst ‘tripping the lightfantastic toe’ to the music of the GinsengPolka.” Overharvesting soon putan end to Minnesota’s ginseng boomlet.About the same time, forward-thinkingfarmers in neighboring Wisconsin experimentedwith cultivating the root.Today, the state of Wisconsin ships ahalf-million pounds of ginseng annually,making it the leading exporter ofcultivated ginseng in the United States.
Americans themselves developed astrong appetite for ginseng only in thepast decade. In 2001, Americans spentabout $170 million on ginseng supplementsand products. Its growth in popularity has come despite the lack of scientificproof that ginseng has medicinalpowers. Last year at OregonStateUniversity,in a study of ginseng’s purportedpsychological benefits, 83 studentsparticipated in a 60-day, placebo-controlled,double-blind, randomized clinicaltrial. The researchers found that thesupplements improved the students’ energyno better than sugar pills.
Other studies, however, suggest thatginseng may have some health benefits.In 2001, the National Institutes ofHealth (NIH), citing a Vancouver study,said that “ginseng does appear to haveantioxidant properties.” Antioxidantsare found in a variety of foods, especiallyfruits and vegetables, and somelab studies suggest they may help preventcertain types of cancer. (Clinicalstudies have been inconclusive.) TheNIH’s NationalCenter for Complementaryand Alternative Medicine notesthat ginseng “may help the body’s disease-fighting and glandular systems.”
Two years ago, clinical trials conductedin Toronto, Canada, suggestedthat American ginseng can lower bloodsugar in Type II diabetics. VladimirVuksan, the study’s lead investigator,says, “We found that what matters isnot only the quantity of ginsenosidesbut the ratio of different ginsenosidesthat determines the effect on blood glucose.”Vuksan, a medical doctor at theUniversity of Toronto’s St. Michael’sHospital, cautions that these results areonly preliminary.
James Gordon, a professor of psychiatryand family medicine at GeorgetownUniversity and one of ginseng’smost respected proponents, says ginsenghas reduced fatigue and other sideeffects in his patients going throughchemotherapy. “It offers them reliefwithout the agitation caused by otherdrugs,” he says. He also believes thatthe root can reduce stress and boost theimmune system.
