A natural toxin in fresh Jin Zhen
Suspected food poison cases caused by consumption of fresh Jin Zhen happen occasionally. Fresh Jin Zhen is the floral part of a plant harvested before it was in blossom. Fresh Jin Zhen has been used in dishes as fresh vegetables. A natural toxin known as colchicine is concentrated in the root of the plant and it is also found in the floral part of fresh Jin Zhen. Poisoning may be resulted from consumption of fresh Jin Zhen which has not been soaked well in water and cooked thoroughly. Symptoms of poisoning may include gastrointestinal discomfort, such as abdominal pain, vomiting and diarrhoea. However, colchicine in Jin Zhen is destroyed during cooking and processing and therefore commercially processed Jin Zhen and Jin Zhen in the dried form are non-toxic.
