A lotion specifically for trichomonas can be made with potassium permanganate, which is prepared as a 1/5000 liquid and then rinsed out of the vagina. Because Trichomonas likes to grow in an alkaline environment, if you use potassium permanganate belongs to an acidic environment, which changes the local environment and makes Trichomonas inhibited, so it is best to use potassium permanganate to douche. Trichomonas can be transmitted through sexual contact, so do not have intercourse during the period of medication, and flush with potassium permanganate every time before inserting the drug into the vagina, which will change the local acidity and alkalinity, so it is more conducive to the healing of the disease as soon as possible. When the clinical symptoms completely disappeared, stop the drug for 3-7 days, go to do the routine laboratory examination of leukorrhea.
