What side effects this plant can have?
This plant can cause severe physiological damage including acute haemolysis, methemoglobinemia, genotoxicity, dermatological ailments, and increased susceptibility to microbial infections. The ingestion or contact with its components may trigger the rapid destruction of red blood cells and impair oxygen transport in the blood. Furthermore, the chemical properties of the plant have been linked to genetic mutations that compromise cellular integrity. Skin exposure frequently results in various dermatological ailments such as irritation or rashes. Finally, its toxic effects can weaken the immune response, leaving the body more vulnerable to harmful microbial infections.

In a case involving a middle-aged man who ingested boiled leaves, clinical symptoms of intravascular haemolysis developed 7 days after ingestion. A peripheral blood smear indicated glucose-6-phosphate dehydrogenase (G6PD) deficiency with acute haemolysis, and G6PD activity remained low during the active period. Although the patient tested negative for common G6PD gene mutations in Southeast Asia, the G6PD level returned to normal after 4 months of follow-up. This suggests that Acalypha indica may induce transient G6PD deficiency.
The main side effects this plant can have are shown in the list below.
- acute haemolysis
- dermatological ailments
