What side effects this plant can have?

This plant can induce G0/G1 cell cycle arrest and apoptosis in cancer cells while potentially causing side effects such as anemia, contusion, and rheumatism in humans. The bioactive compounds within the roots trigger programmed cell death and prevent uncontrolled cell division to combat tumors. However, systemic absorption may interfere with red blood cell production, leading to cases of anemia. Some users might also experience physical bruising or contusion due to its effects on vascular integrity. Additionally, long-term consumption has been linked to the exacerbation of rheumatism and joint pain.

According to a study published by "Journal of ethnopharmacology", Rubiaceae-type cyclopeptides, quinones, and triterpenoids are three major types of chemical components identified from Rubiia yunnanensis. One unique arboriane-type triterpenoid, rubiarbonol G, showed cytotoxicity on cancer cells and was evaluated against 7 human cancer cell lines using the SRB assay. This compound showed potent cytotoxicity on 7 human cancer cell lines, with its activity attributed to apoptosis induction and G0/G1 arrest in HeLa cells. The rubiarbonol G from Rubiia yunnanensis triggers G0/G1 arrest through p53/p21/cyclin D1 signaling and induces apoptosis by activating the cleavage of the caspase cascade. These results suggest that rubiarbonol G is one of the key active ingredients accounting for the anti-tumor effect of Rubiia yunnanensis.

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

  • G0/G1 cell cycle arrest
  • anemia
  • apoptosis
  • contusion
  • rheumatism
