Herbs Toxicity

Many Herbal products are innocuous or possess minimal toxicity, some contain toxic ingredients that may not be identified on the label. These unidentified ingredients may be unintentionally included in the product (eg, misidentification of a toxic plant as a desired nontoxic plant or contamination with pesticide residues or heavy metals) or adulterants introduced for increased effect (eg, addition of a pharmaceutical agent to an herbal preparation) called herbal toxicity.
