**********
Many herbals are contaminated with lead, cadmium, mercury, and arsenic. In recent years, this has especially been an issue with tongkat ali.
The European Commission has set the following limits for the four pollutants, which are all powerful poisons when absorbed into biological systems:
Lead < 10 ppm
Cadmium < 1 ppm
Mercury < 1 ppm
Arsen < 3 ppm
The measurement ppm means parts per million (10000 ppm = 1%).
