There are many kinds of vaginitis, and there are more douches that can be used for trichomoniasis, such as bitter ginseng lotion, compound cypress lotion, adamantine lotion, and wet and itchy lotion. When a patient has trichomoniasis, the main treatment is through local antibiotics placed in the vagina, such as metronidazole suppositories. The lotion is only an adjunctive treatment. Before placing the medication in the vagina, women should wash their vulva and hands and use the lotion to flush out the excessive leucorrhea and medication residue from the vagina. After trichomoniasis is cured, the patient should not use the lotion to douche the vagina until three days before the next review of the leukorrhea.
