A small amount of Lactobacillus means that there is a small amount of Lactobacillus in the vagina. The role of Lactobacillus is to balance the normal flora in the vagina, avoid the growth of pathogenic bacteria and play a role in defending against vaginitis. If there is a high amount of Lactobacillus, the possibility of causing vaginitis is relatively low. It is recommended that if a woman has vaginal inflammation, especially recurrent vaginal inflammation, after treatment with medication, if the pathogenic bacteria have turned negative, a course of Lactobacillus capsule can be inserted into the vagina to improve the local resistance and avoid the recurrence of vaginitis.
