Symptoms of poisoning from eating lotus root

Under normal circumstances, eating lotus root usually does not cause poisoning. Lotus root is an aquatic vegetable with high nutritional and medicinal value, and its consumption is beneficial to health. However, side effects may occur if the water is polluted or if spoiled lotus root is consumed. The details are as follows:

Lotus root itself does not cause poisoning in humans. It is white in color, crisp in texture, and sweet in taste, possessing high culinary value. In traditional Chinese medicine, raw lotus root is considered cooling in nature and can promote saliva production and cool the blood, while cooked lotus root is warming and can tonify the spleen and nourish the blood, reducing fat absorption. Therefore, lotus root itself is non-toxic. However, if grown in polluted water, the lotus root may become contaminated, and consuming such contaminated lotus root can easily lead to gastrointestinal discomfort. Additionally, eating spoiled or undercooked lotus root may result in food poisoning, causing symptoms such as nausea, vomiting, abdominal pain, and diarrhea. Patients are advised to visit a qualified hospital for tests including complete blood count and stool analysis, and receive fluid replacement and acid-suppressing, stomach-protecting treatments under medical guidance. Moreover, excessive pesticide residues may also lead to symptoms such as nausea, vomiting, abdominal pain, and diarrhea; severe cases may present with increased salivation, sweating, and drooling.

If the above symptoms appear shortly after consumption, prompt induced vomiting is recommended. Severe cases require immediate medical attention. Lotus root is difficult to clean thoroughly, so special attention should be paid to whether mud or sediment remains inside the root's holes during washing. Discolored lotus root should not be eaten, to avoid potential poisoning.
