The only way to ensure the purity and integrity of herbal medicine production is through eternal vigilance. This must include a stringent and rigorous sampling regime. Only through comprehensive sampling can control over quality be maintained.
When you purchase herbal medicines do not accept bland assurances that samples have been taken of the raw herbs. A sample is only reliable if represents the whole batch. Here is a brief overview of the Herbs in a Bottle sampling procedure:
All deliveries of raw herbs are sampled, with samples taken from the upper (not less than 10cm from the top), middle and lower parts of a container or package. Samples of seeds are withdrawn with a grain probe. In mass samples must be as uniform as possible.
The average sample is quartered - dividing it diagonally into four equal parts. Two opposite parts are carefully mixed, and the process repeated until the required quantity is obtained for the testing to be carried out. A portion of the final sample is retained to act as a reference.
Tests are carried out on the following:
If the sample fails the tests the batch cannot be used in production.

Tests are carried out on the following:
- Organoleptic characteristics (colour, texture, odour)
- Presentation of material (raw, crushed, cut compressed)
- Presence of admixtures, foreign matter (sand, glass, particles, dirt), mould or signs of decay
- Presence of insects
- Presence of packaging material originating from poor or degraded containers
If the sample fails the tests the batch cannot be used in production.
