Safety & Hazards

All parts of the plant contain tannins. Whilst tannins are found in many foods, and have a range of medicinal uses. They are usually only present in low concentrations. In some foods made from oaks (particularly the seeds), the tannin content can be quite high unless the food is treated to reduce tannin content. Tannins are only of low toxicity and, because of their bitter taste and astringency, are unlikely to be eaten in large quantities. However, if they are taken in excess, they can cause stomach pains; constipation followed by bloody diarrhoea: excessive thirst; and excessive urination[ 293 Title Poisonous Plants of North Carolina Publication Author Website http://www.ces.ncsu.edu/depts/hort/consumer/poison/poison.htm Publisher Year 0 ISBN Description An excellent concise but comprehensive guide to toxic plants that grow in N.
