What side effects this plant can have?
This plant can cause serious health complications including acute liver injury, hepatotoxicity, abdomen pain, constipation, and diarrhea. While it is often used in traditional medicine, excessive consumption may lead to significant damage to liver functions. Some individuals report gastrointestinal distress such as persistent diarrhea or uncomfortable constipation after ingestion. Severe cases have been documented where the plant triggers acute liver injury through direct hepatotoxicity. Therefore, caution is necessary when using this species due to these potential adverse effects.
According to a study published by "BMC complementary and alternative medicine", Aegle marmelos is used in Indian traditional medicine to treat fever, abdomen pain, heart palpitation, urinary troubles, melancholia, anorexia, dyspepsia, diabetes, and diarrhea. In a study involving rats where diabetes was induced by a single 60 mg/kg injection of STZ, umbelliferone β-D-galactopyranoside (UFG) from the stem bark was administered at doses of 10 mg/kg, 20 mg/kg, or 40 mg/kg for 28 days. While UFG showed significant (P < 0.001) improvements in fasting blood glucose and insulin, it also caused an increase in body weight and changed glucose utilization in oral glucose tolerance tests. Regarding lipid profiles, UFG treatment increased levels of cholesterol, triglycerides, VLDL, and LDL cholesterol, while decreasing the level of HDL cholesterol. Histologically, while diabetic rats showed inflammatory cells in blood vessels, intercalated discs, fat degeneration, and focal necrosis, these effects were less obvious in the groups treated with UFG.
The main side effects this plant can have are shown in the list below.
- abdomen pain
- acute liver injury
- constipation
