NNFA St. John's Wort Test Discredits Good Housekeeping Results.

  In March 1998, a study sponsored by Good Housekeeping Magazine revealed a 17-fold difference in hypericin levels in six widely-available brands of St. John's wort capsules, and a seven to eight-fold differential in three popular liquid extracts. The report concluded that there was a "startling lack of consistency" between the amount of hypericin found in tests, compared to the label claims. The results were announced at a "Consumer Safety Symposium" in New York City which was attended mainly by the national consumer press. In July, Paracelsian Inc., performing tests on six St. John's wort products for The National Nutritional Foods Association (NNFA), found that Good Housekeeping failed to take variations in capsule weight, nonactive ingredients, and dosage into account in its testing. Utilizing the proprietary BioFIT™ functional quality assurance model, Paracelsian is now providing the first independent confirmation of consistent biological activity for products of all kinds. The NNFA maintains that Good Housekeeping had an agenda to create consumer doubt about the safety and efficacy of dietary supplements.
