What side effects this plant can have?
This plant can cause serious health issues including alteration of thyroxine level, developmental toxicity, idiosyncratic drug-induced liver injury, impaired locomotor behavior, and thyroid endocrine disruption. Research indicates that its chemical components can significantly interfere with hormonal balance through thyroid endocrine disruption. These changes often lead to a measurable alteration of thyroxine level in biological systems. Furthermore, exposure has been linked to developmental toxicity that may affect growing organisms. Clinical observations also suggest risks of idiosyncratic drug-induced liver injury and impaired locomotor behavior in certain subjects.
According to a study published by "Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association", icariin (ICA) isolated from Epimedium brevicornu Maxim causes developmental toxicity in zebrafish larvae. When embryos were exposed to ICA at concentrations of 0, 2.5, 10, and 40 μM, treatments with 10 and 40 μM resulted in reduced hatching rates, decreased body length, and abnormal swim bladders. Exposure to 40 μM ICA caused a remarkable alteration of T4 levels and a significant decrease in the T3/T4 ratio, indicating thyroid endocrine disruption. Furthermore, ICA exposure led to the up-regulation of nkx2.1 and tg genes, while significant down-regulation of the dio1 gene was observed in the 10 and 40 μM groups. These findings suggest that ICA causes developmental toxicity through the disruption of thyroid development and hormone synthesis.
The main side effects this plant can have are shown in the list below.
- alteration of thyroxine level
- developmental toxicity
- idiosyncratic drug-induced liver injury
- impaired locomotor behavior
- thyroid endocrine disruption
