e-Phytovigilance: Internet and natural product pharmacovigilance
Despite the use of phytotherapy is constantly increasing, consumers and health professionals often ignore important issues regarding possible interactions between herbs and drugs, their adverse effects or, simply, the ineffectiveness of many products. On the contrary, just because the use of natural health products is not well regulated, many herbal products are not adequately tested for their pharmacology and toxicology, especially when used during pregnancy and breastfeeding.
