Food Allergics Beware: Herbal Products May Contain Surprise Ingredients Read more: http://healthland.time.com/2013/10/12/food-allergics-beware-herbal-products-may-contain-surprise-ingredients/#ixzz2hge0IfdB

They found that 60% of the products contained plant species that were not listed on the label, and 20% used fillers like rice, soybeans, and wheat which were also not divulged on the bottles.

For instance, products sold as St. John’s wort supplement, which is sometimes used to treat depression, contained Senna alexandrina, which is a plant that spurs laxative symptoms. Other products contained Parthenium hysterophorus (feverfew), which is known to cause swelling and mouth numbness.

But a consumer has a right to see all of the plant species used in producing a natural product on the list of ingredients,” lead author Steven Newmaster, an integrative biology professor at the Guelph-based Biodiversity Institute of Ontario said in a statement.
