Heavy Metals,Chinese Herbs & California's Proposition 65
September 2001
Mayway has been in operation for 32 years and has been privileged to be a part of the growth and acceptance of traditional Chinese medicine in America today.Through the years we have worked to bring an awareness of the value of traditional Chinese medicine in promoting health and wellness.
Our role is one of leadership.We have participated in solidifying the status of traditional Chinese medicine through the support of trade organizations,research programs,community outreach and political activism.
Mayway has been at the forefront of raising the standards of quality control within our industry.Over time we have become more vigilant in the sourcing of herbs,as well as the manufacturing and quality control of the goods we import.We have built our own herb processing facility in China to control the quality of herbs from the field to your door.Working with internationally certified GMP factories,we have created the Plum Flower® Brand line to ensure that high quality traditional medicines are available in the American and European marketplaces.
Mayway is a responsible supplier that maintains strict quality control standards for heavy metals,independent of Proposition 65.These standards as well as Proposition 65 issues are described below.
Our Pledge
Mayway will continue to do the following for all products intended for sale in California:• We will provide the Proposition 65 warning on all products that do not have test data confirming that all heavy metals are below Proposition 65 "no significant risk" and "no observable effect" levels.
• We will continue to reject batches of Plum Flower® and Min Shan® Brand products if heavy metals exceed Company standards (outlined below) regardless of warnings.
• We will endeavor to look for new sources and new technologies in an effort to further reduce or eliminate the presence of heavy metals in our products.
Our Quality Control Standards
Each and every batch of Plum Flower® and Min Shan® Brand pills is tested for heavy metals.As there are presently no State or Federal heavy metal guidelines for traditional Chinese medicines,we researched our own.We were guided to the U.S.Pharmacopoeia (USP) to determine safe heavy metal levels for our products.USP levels are lead 10 ppm*,cadmium 3 ppm,arsenic 3 ppm,and mercury 3 ppm.However,as the factories we work with have GMP certification granted by the Australian Therapeutic Goods Administration (Australia's FDA equivalent),we also looked at their heavy metal guidelines.We found their levels to be even lower for lead at 5 ppm,and adopted the Australian standard as our own.Each batch of Plum Flower® and Min Shan® Brand pills is tested to these standards both at the factory and at third party labs for extra quality assurance.
Our ongoing commitment to improve quality control
We work to continually improve the quality of our products.We have always done microbial,sulfur and general heavy metals testing on our Plum Flower® Brand un-sulfured bulk herbs.In addition,since January of 2001,we have also been testing our bulk herbs specifically for lead,arsenic,mercury and cadmium.We have also been testing and setting limits for DDT and benzene hexachloride,two very toxic and banned pesticides.Our most recent achievement (July,2001) of source improvements have allowed us to further lower our heavy metal limits for Plum Flower® and Min Shan® Brand formulas to 3 ppm for lead,2 ppm for arsenic,0.5 ppm for mercury,and 1 ppm for cadmium.We continue to gather data on soil pollution where herbs are grown allowing us to make ever more informed choices regarding herb sourcing as we strive for cleaner,more pure herbs and herbal products.

传统中医可能确实对重金属没什么相关的研究吧？我也不太清楚……而且要外文的，难度相当的大。
