What side effects this plant can have?

This plant can cause significant reproductive complications including increased uterine wet weight, prevention of conception, and vaginal cornification. These physiological changes suggest that the plant possesses potent hormonal activity that disrupts the normal menstrual cycle. The observed increase in uterine weight often indicates an imbalance in estrogenic or progestogenic signaling within the body. Such hormonal shifts directly interfere with the ability to maintain a pregnancy or achieve successful fertilization. Additionally, the process of vaginal cornification serves as a clinical marker for altered steroid hormone levels in the reproductive tract.

According to a study published by "Pakistan journal of pharmaceuctical sciences", the methanolic root extract of Carpolobia lutea was tested at doses of 7-21mg/kg via intraperitoneal route for four days. When administered to mice and rats, the extract prevented conception for two gestational periods. Significant changes were observed in the length and weight of pups with p<0.05-0.001, although no abnormalities were seen in the pups over thirty days. In ovariectomized immature young rats, the 7-21mg/kg extract doses produced estrogenic effects like increased uterine wet weight at low doses, while high doses showed anti-estrogenic effects. These results were compared against a standard drug of 0.1µg/rat/day of 17-beta-estradiol.

The main side effects this plant can have are shown in the list below.

  • increased uterine wet weight
  • prevention of conception
  • vaginal cornification
