On 8/8, Ninh Binh Obstetrics and Pediatrics Hospital reported admitting a 3-year-old boy from Hoa Lu ward for loc mai leaf poisoning.

The boy's family explained they had brewed a traditional remedy using loc mai leaves five days prior to treat his constipation. After ingesting the concoction, the boy exhibited symptoms like dark red urine, fatigue, nausea, and jaundice, prompting his family to seek medical attention.

At the hospital, the boy was diagnosed with severe anemia, acute hemolysis triggered by the loc mai leaves, and G6DP deficiency. He received blood transfusions and corticosteroids, and his vital signs were closely monitored. After two days of treatment, his condition improved significantly. His fatigue subsided, his skin and mucous membranes regained their normal color, his urine returned to an orange-red hue, and his appetite improved.

Doctor Truong Cong Thanh, Head of the Emergency Department, explained that the G6DP enzyme is present on the surface of red blood cells. Individuals with G6DP deficiency who ingest loc mai leaves (which contain hemolytic agents) can develop acute anemia and damage to the liver, kidneys, and other organs. Without timely treatment, this can be life-threatening.

Doctor Thanh advised against using loc mai or other plant leaves for medicinal purposes based solely on traditional practices without scientific evidence, especially for those with G6DP deficiency. If poisoning symptoms appear, seek immediate medical attention.

Loc mai (also known as "moi" in some regions) refers to the leaves of the loc mai tree, a wild plant growing 2-3 meters tall. Because of its laxative effect in small doses and purgative effect in larger doses, it is sometimes used in folk remedies for constipation and dysentery. However, large quantities can be toxic.
