What side effects this plant can have?
This plant can cause significant physiological harm through its ability to induce apoptosis, oxidative damage, contraction of the extracorporeal womb, and antifertility. The presence of specific toxic compounds triggers programmed cell death in various tissues, leading to widespread cellular degradation. These substances also promote the formation of reactive oxygen species, which results in severe oxidative damage to cellular structures. Furthermore, the plant exhibits potent effects on reproductive systems by causing the contraction of the extracorporeal womb. These combined mechanisms ultimately result in antifertility by disrupting normal reproductive processes and hormonal balances.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", the dichloromethane extraction of Daphne genkwa acts as a toxic polar fraction. This fraction can obviously decrease the levels of SOD, Na⁺-K⁺-ATPase, Ca²⁺-Mg²⁺-ATPase (P<0.01) and the content of GSH, while increasing LDH and MDA levels in cell supernatant (P<0.01). Furthermore, the plant extract obviously increases the early and late apoptotic rate of IEC-6 cells, decreases the proportion of G1 stage cells, and increases the ratio of S stage and M stage cells (P<0.01). Vinegar processing significantly reduces this toxicity (P<0.01) by increasing the levels of SOD, Na⁺-K⁺-ATPase, Ca²⁺-Mg²⁺-ATPase (P<0.01) and GSH. This processing also decreases LDH and MDA levels (P<0.01), decreases the early and late apoptosis rate (P<0.01), and increases the proportion of G1 stage cells while decreasing the ratio of S stage and M stage cells (P<0.01).
The main side effects this plant can have are shown in the list below.
- antifertility
- apoptosis
- contraction of the extracorporeal womb
- oxidative damage
What herbs are paired with Daphne genkwa?
