1. Inhibitory effect
Colchicine can bind to tubulin dimer, prevent tubulin conversion, and stop cells in the middle of mitosis to death.
Through nimal experiments, it is found that colchicine can reduce the death of male mice with toxic liver necrosis, preventing carbon tetrachloride-induced liver fibrosis and improving its liver function. Through experiments in China, it is also confirmed that colchicine can reduce the formation of collagen fibers in liver, reducing liver fibrosis. Clinical trials have shown that colchicine can improve symptoms, reducing the liver and spleen, reducing intrahepatic fibrous tissue and increasing liver blood flow. In conclusion, vivo and in vivo experiments have shown that colchicine can inhibit the proliferation of fibroblasts, inhibit the expression of collagen and protein synthesis, promote the activity of collagenase, increase the activity of MMP-1 and MMP-9. Thereby colchicine can reduce the production and deposition of collagen, promote collagen decomposition, and play a role in anti-fibrosis. Inhibiting mast cells from releasing histamine particles, pancreatic beta cells from releasing insulin, and the movement of melanin particles in melanoma cells.
2. Anti-inflammatory Effect
By interfering with lysosomal degranulation, colchicine can reduce neutrophil activity, adhesion and chemotaxis, inhibit granulocytes from walking to inflammatory area, thus playing a role in anti-inflammatory effect. In addition, it interferes with the expression of intercellular adhesion molecules and selectin, thereby preventing T lymphocyte activation and adhesion to endothelial cells, inhibiting the inflammatory response. Colchicine can also play a role in anti-inflammatory effect by reducing the expression of E-selectin, L-selectin and endothelin.
3. Other Effect
Colchicine can reduce body temperature, inhibit the respiratory center, enhance the role of pseudo-sympathetic drugs, contract blood vessels and elevate blood pressure. Colchicine also enhances gastrointestinal function and changes the function of the neuromuscular junction through neuronal stimulation. As colchicine can inhibit cell division, interfere with the tumor cell protein metabolism, inhibit RNA polymerase activity and cell membrane lipid synthesis and amino acid transport on the cell membrane, thereby inducing apoptosis of a variety of solid tumor cell. The study found that in vitro glioma cell growth was significantly inhibited and apoptosis induced by colchicine.
Colchicine may reduce white blood cell activity and phagocytosis and lactate acid formation thus reducing the deposition of uric acid crystals, and inflammatory response to reach analgesic effect. It can treat the acute onset of gouty arthritis, prevent recurrent gouty arthritis from acute attack. It's mainly for acute gout, invalid to general pain, inflammation and chronic gout.
Colchicine can inhibit cell mitosis. Because of its high toxicity, now it is less used.
Colchicine has significant effect on breast cancer.

Application and Function
1. It is anti-gout, anti-tumor, inhibiting the mitotic cell stopping in M phase.
2.It has the significant effects on breast cancer, cervical cancer, esophageal cancer, lung cancer,gastric cancer and chronic myelogenous leukemia.
3.It also can be used for acute gout, anti-inflammatory analgesic.
4.In recent years ,furtherly expand its clinical application, for example:to prevent atherosclerosis damage;to cure the liver cirrhosis; to relief the cycle heat caused by abnormal catecholamine, the Behcet's disease; the lumbar disc herniation,intractable waist pain and sciatica; prevent intestine adhesion.
5.In addition, its used as the treatment of Purple epilepsy caused thrombocytopenia; Persistent apophysis erythema;Advanced schistosomiasis;
6.Moreover, using colchicine three can get the polyploidy,so Colchicine is indispensable in chromosome research.

||Pharmaceutical and food
||Colchicine is a toxic natural product and secondary metabolite, originally extracted from plants of the genus Colchicum (Autumn crocus, Colchicum autumnale, also known as the "Meadow saffron"). Originally used to treat rheumatic complaints and especially gout, it was also prescribed for its cathartic and emetic effects. Its present medicinal use is mainly in the treatment of gout; as well, it is being investigated for its potential use as an anti-cancer drug. It can also be used as initial treatment for pericarditis and preventing recurrences of the condition. In neurons, axoplasmic transport is disrupted by colchicine
