“…Non-Asian herbal products, such as those from Africa (81,63), Europe (82,83), South America (61,84), and Mexico (85) have also been reported to contain high concentrations of toxic elements and pose a serious health risk. For example, a Brazilian study (61) revealed that the estimated lead intake through horse chestnut reached 440 % of the PTWI value, which would signifi cantly increase body lead burden if the product were taken on a long-term basis.…”

Medicinal plants have a long history of use in therapy throughout the world and still make an important part of traditional medicine. Thus, medicinal plants and herbal products must be safe for the patient (consumer). This review addresses biological contaminants (microbes and other organisms) and chemical contaminants (mycotoxins, toxic elements such as heavy metals, and pesticide residues) as major common contaminants of medicinal herbs and herbal products. To prevent and screen for contamination and ensure safety and conformity to quality standards, medicinal herbs and herbal products should be included in appropriate regulatory framework.

“…Metals such as iron, copper, zinc, and manganese are essential metals since they play an important role in biological systems, whereas cadmium, arsenic, and lead are nonessential metals as they are toxic even in traces (Unak et al 2007). The essential metals can also produce toxic effects when the metal intake is excessively elevated (López et al 2000;Lekouch et al 2001).…”

Herbal tea is consumed widely in China due to their therapeutic efficacy, mild features, and relatively low cost. To assess the health risk associated with drinking herbal tea, arsenic and seven heavy metals, namely Cu, Zn, Fe, Mn, Cd, Ni, and Pb in eight different types of herbal flowers and their infusions were determined by inductively coupled-mass spectrometry after microwave digestion. The accuracy and precision of the analytical method were confirmed by the certified reference material (GBW 07605). The results suggested that significant differences existed in all metal concentrations determined among different varieties of herbal flowers and their infusions. In general, the concentration of iron was higher than those of seven other metals in the investigated herbal flowers and their infusions. The hazard quotient (HQ) and hazard index (HI) were calculated to evaluate the noncarcinogenic health risk from individual metal and combined metals due to the dietary intakes via consumption of herbal infusions. Both the HQ and HI levels were far below one, suggesting that the dietary intakes of the eight metals determined from daily consumption 4.5 g of the investigated herbal flowers for a normal adult should pose no potential risk to human health.

“…In addition, kohl is known to prevent sun glare, thus it was used by Bedouins in the Arab Peninsula. Previous studies [2][3][4] have shown that kohl contains toxic heavy metals, such as lead, and case studies have revealed that blood levels were significantly higher in individuals who used kohl compared to ones who did not. It was also shown that blood levels in infants of kohl using mothers were considerably higher than those of non-kohl using mothers (5.2 g/dl versus 2.8 g/dl) [5].…”
