Yes, the products are tested for pesticides, heavy metals and microbiological contamination. There are only used ingredients and herbal products that meet our rigorous standards for safety. The traditional methods of Ayurveda are followed while employing the highest standards of quality control. To ensure purity, Maharishi AyurVeda products are tested before, during and after manufacture and then tested again by an accredited independent analytical laboratory (that meets ISO 17025 standards), prior to distribution. MA/Veda herbs are tested once at our manufacturing facility. These tests include examination for:

• Heavy metals (lead, arsenic, cadmium and mercury)
• Residual pesticides (at the start of the manufacturing process)
• Microbiological contamination (including E. coli, coliforms, staph and salmonella)

Maharishi's products far exceed the testing guidance of the American Herbal Products Association (AHPA) and specifications of the American National Standards Institute (ANSI).
