Heavy metal poisons

Ayurvedic medicines can contain dangerous quantities of heavy metals, including lead, mercury, thallium and arsenic, say clinical toxicology specialists in London. Writing in the International Journal of Environment and Health, they warn that recent legislation within the European Union, which was aimed at improving safety of shop-bought products, will have little impact on medicines prescribed by traditional practitioners, those imported by individuals from overseas or bought direct over the Internet or by mail order. Heavy metals are added deliberately to many Ayurvedic "remedies" as part of the treatment which aims to rebalance the body and is claimed to treat a huge range of diseases from asthma to cancer.
