Poisoning can occur when consuming excessive amounts of alum, especially in patients with a high number of previous primary underlying diseases, poorer immunity in old age, and weaker underlying physical condition. If a large amount of alum is consumed, it can lead to aluminum sulfate and potassium sulfate poisoning because it contains a large amount of aluminum ions and potassium ions, which can lead to impaired absorption of ionic components such as calcium and iron after excessive intake. First, the patient will develop osteoporosis. Secondly, it will lead to anemia. Finally, it will affect the development of the nervous system and nerve cells. When alum is consumed in excess, different degrees of toxicity can occur, such as nausea, vomiting, acid reflux, heartburn, dizziness, head swelling, headache, and disorientation. If any of these conditions occur, it is important to visit a hospital for medical attention.
