It is for this reason that I have taken the time to compile this information detailing the processes that herbs, vitamins and other products should go through before they reach your home.
You will want to be certain that at the very least they are using the following test procedures. If you call a manufacturer and ask them if they are using these procedures, their responses should be a direct "yes" or "no" - not evasive without good reason.
After testing is completed according to the individual raw material specifications, the raw material is accepted if it meets specifications and rejected if the results show it does not meet Nature's Sunshine's highest standards of quality.
- Lot code on each bottle to ensure traceability. Use the lot code number if you have to call Customer Service with a question.

- For liquid products, the correct amount of liquid in each bottle
- Auditing for microcontamination
- Physical appearance of each product
The Bactometer includes the following components: workstation computer, color data terminal and keyboard, printer and bactometer processing unit (BPU).
Coliforms ferment the lactose in the medium to produce gas. This gas is trapped around the coliform colony and allows the differentiation of the coliform bacteria from other gram negative bacteria. In addition, glucuronidase will react with the indicator in the media to produce a blue precipitate around the colony allowing visual identification of E.coli. All non-blue gas-forming colonies are coliforms.
With gas chromatography, the individual components of complex mixtures are separated into independent peaks (peaks seen in graph form on a screen). With the mass spectrometer, these individual peaks can be measured and positively identified.
Every herb has a characteristic mineral content and a corresponding typical ash content. If we measure an ash content that is significantly higher than the typical ash content, we can suspect that there is dirt or other adulteration present. Dirt is a common problem, especially with root materials. Harvesters may not take the time to completely clean the surrounding dirt from the roots. This leads to the occasional rejection of some herbs.
