Nano silver technology
Silver has generally been recognized for its antibacterial effect, and this is due to its oxygen therapeutic action blocking the bacterial cell wall and blocking bacterial DNA replication for its bactericidal actions. different creatures. In general, an antibiotic can kill 6 different types of bacteria, but silver can kill 600 different types of bacteria.
Silver is also a non-toxic material for tools, so the application range of silver is quite wide and has a long history. See through the high-tech nanotechnology mode, making silver particles is working to become big, antibacterial function is enhanced, and the quality of home environment and Personal Hygiene is increased significantly.
Nano silver solution containing nano-sized fine particles and dissociated silver ions have significant bactericidal effect. Nano silver all have 99.99% inhibitory effect on escherichia coli, staphylococcus aureus, Salmonella and bacillus pyocyaneus, etc. under multiple dilution conditions.
Or can strongly attract proteic sulfydryl in the bacterial body, rapidly combine with it to reduce the enzymatic activity of antibacterial protozoa, thus producing antibacterial effect; By the slow release of silver ions, it is possible to exert a persistent antibacterial effect.
Vaginitis and cervicitis are reproductive tract infections in women with a higher incidence, and the physical and mental health of women and their relatives are significantly affected. Although there are many therapeutic products on the market, all are undesirable in terms of dosage form, method of use, therapeutic effect.
Colitis is caused by bacteria, mycete, chlamydia, mycoplasma, virus, protozoon … The source of infection from the vagina can go up to the uterine cavity, fallopian tubes, ovaries and pelvic cavity, thereby causing endometritis. endometriosis, salpingitis, salpingitis or pelvic infection of the person with acute and chronic, and chronic infection can even cause bowel obstruction and infertility except for the inflammatory symptom.
