Herbal extracts may be contaminated adulterated and may contain toxic compounds.

Herbal medicines are in widespread use and although many believe herbal medicines are safe, they are often used in combination and are drawn from plant sources with their own variability in species, growing conditions, and biologically active constituents.
However, there is a lack of a systematic approach to assess their safety and effectiveness. A variety of materials has been produced, such as monographs on herbs and preparations, guidelines on good agricultural and collection practice for starting materials of herbal origin, and guidelines on the standardization of applications and setting up pragmatic approaches for identification and quantitative determination of herbal preparations and their complex compositions ( Routledge 2008 ; Vlietinck, Pieters, and Apers 2009 ). The standards put forward allow not only to define the quality of products but also to eliminate harmful compounds, adulteration, and contamination.
Product license holders are required to monitor all adverse reactions associated with their product and report serious adverse reactions to the Canadian Department of Health. The GMPs are designed to be outcome based, ensuring safe and high-quality products, while giving the flexibility to implement quality control systems appropriate to the product line and business. In addition, GMPs must be employed to ensure product safety and quality.
A site license is also needed for those who manufacture, pack, label, and import herbal medicines. Once a product has been granted a license, it will bear the license number and follow standard labeling requirements to ensure that consumers can make informed choices. Dietary supplements do not need approval from the Food and Drug Administration (FDA) before they are marketed ( FDA 2010 ). Under DSHEA, herbal medicines, which are classified as dietary supplements, are presumed safe, and the FDA does not have the authority to require them to be approved for safety and efficacy before they enter the market, which is the case for drugs.
