American Botanical Council Presents Free Screening of The Meaning of Tea

(Austin, Texas. November 30, 2011) The American Botanical Council announces the publication of "A Brief History of Adulteration of Herbs, Spices, and Botanical Drugs" by noted botanist, author, and photographer Steven Foster.1 The article appears in the just-released Fall 2011 issue of HerbalGram (#92).1

In the paper, Foster—who is also ABC's Board of Trustees president—provides an overview of the history of adulteration stretching back to Greco-Roman Antiquity.

Foster defines "adulteration" in the paper as "accidental, negligent, or intentional variations in identity, strength, purity, and expected outcomes from a named or at least implied identity of a drug" or food, spice, or dietary ingredient.

The article begins by emphasizing, via a humorous quote, that the practice of botanical adulteration likely began much earlier than Classical times:

"Since the memorable occasion upon which young Eve palmed off the green apple on old man Adam, more or less fraud in food handling has occurred, as opportunity has offered and occasion for profit has suggested. In the adulteration of drugs even more elasticity of conscience has been necessary to permit the almost unlimited sophistication which has been practice from time immemorial."

In a detailed and compellingly narrative fashion, the article describes 1st century methods of adulteration detection, the medieval Islamic practice of having an amin present during medicine preparation to "thwart adulteration," legislative reaction to botanical adulteration in 19th century Britain, and the Ginger Jake epidemic that crippled many US citizens during Prohibition. Foster then outlines contemporary incidents of adulteration.

"We commissioned Steven Foster to write this article as we believe it is important to frame the issue of accidental and intentional adulteration of botanical ingredients in the historical perspective," said ABC Founder and Executive Director Mark Blumenthal. "It is essential for people to realize that adulteration is an ancient and ongoing practice: unfortunately, people have been cheating in commerce since the beginning of civilization!"

"I have found the topic of adulteration fascinating ever since I first encountered catnip stem-chaff left over from catnip seed harvest masquerading as catnip herb over 30 years ago," said Foster. "Proper verification and authentication of botanicals and plant parts entering commercial trade is of increasing importance to discerning consumers demanding high-quality herbal products to deliver expected benefits. Quality is not a marketing slogan; it is a consumer right. A spectrum of sophisticated technology exists to thwart adulteration problems. However, history teaches us that there is no technological substitute for knowledgeable and experienced human perception. It is the foundation from which technology becomes useful."

The article contains historic illustrations and Foster's own plant photography. It was peer reviewed by five experts in the history of pharmacy and medicine and additional expert reviewers. The article is the first in a series of articles and white papers on adulteration of botanical materials used in foods, spices and food flavorings, dietary ingredients, drugs, and cosmetics as part of the ABC-AHP-NCNPR Botanical Adulterants Program, a recently-announced consortium of nonprofit organizations and independent analytical laboratories headed by the American Botanical Council, the American Herbal Pharmacopoeia, and the National Center for Natural Products Research at the University of Mississippi. 

"This program is the first time a wide range of members of the herb, dietary supplement, analytical laboratories, industry trade organizations, and others in various segments of the botanical ingredients industry have come together to support a self-regulatory educational process to identify and reduce the level of accidental and intentional adulteration of botanical materials used in numerous consumer goods," said Blumenthal. "But," he added, "as this article cogently demonstrates, adulteration has been with us for thousands of years. The best we can do is help suppliers and manufacturers identify problems and produce reliable ingredients, and hope that the regulatory agencies will do their part in enforcing existing laws and regulations."
