How can I be sure of the quality and purity of the herbs I purchase?

Selection of Quality Herbs

To be confident that the herbs that you use are of the highest potency, quality, and safety; only use herbs from manufacturers that are certified by the Therapeutic Goods Administration of the Australian government as having Good Manufacturing Practice (GMP) - a hygiene guideline even more strict than in the United States.  

Do not use endangered species (plant or animal), and promote wildlife conservation through the use of surrogate natural substances.
