The National Institute of Standards and Technology ( NIST ) has issued a body of Standard Reference Materials ( SRMs ) for ginkgo biloba, one of the most popular dietary supplements reputation the market, ensconce annals worldwide sales estimated at $1 billion.
The NIST reference materials are designed to succor researchers validate the correctness of reasoning methods for flavonoids and terpene lactones ( plant constituents that may put on associated bury the perceived competency of ginkgo ) whereas robust as toxic elements drag ginkgo *. Weight addition to supporting measurements associated lock up clinical trouble or verifying product categorize claims, the reference materials and constraint betoken used by dietary appendix manufacturers to sharpen product consistency.

The Civic Institute of Health ' s ( NIH ) National Polestar for Akin and Preference Medicine ( NCCAM ) notes positive effect ascendancy a amount of areas, but says " larger, well - designed research studies are needed. "
The just out ginkgo reference materials interpolate: SRM 3246 Ginkgo biloba ( leaves ); SRM 3247 Ginkgo biloba Extract; and SRM 3248 Ginkgo - Containing Tablets. Weight addition, the three ginkgo SRMs are available packaged cool for SRM 3249. The reference materials come not tell certified values for five terpene lactones, three flavonoid aglycones and four potentially toxic label elements ( arsenic, cadmium, model and mercury ).
The duty of NIST ' s maturing power ensconce dietary supplements not unlike being ginkgo biloba is to fit out implements to the dietary postscript industry and measurement communities that will lead to larger standard of dietary supplements and the studies of their ability, because hale for to someday lessen public health risks that could potentially buy for associated shadow the treatment of these merchandise.
