Abstract
The present invention provided an anticancer nano-silver composition for the treatment and prevention of cervical cancer. The composition contains nano-silver powder 3-200 mg/kg, carbomer 700-1000 mg/kg, triethanolamine 700-1000 mg/kg, glucose 2.8-3.2 g/kg, and water as remaining; of the nano-silver powder, wherein the purity of silver is ≥99.99% and particle size is 1-5 nm. Experiments demonstrated that the anticancer nano-silver composition can be used to inhibit HeLa proliferation, and cause cell death. The anticancer nano-silver composition of the present invention can be used to manufacture medicaments for the treatment and prevention of cervical cancer.
