It is normal to have sticky streaks with menstruation, which is due to the flow of blood caused by the shedding of the lining. Most menstruation is just sticky. For small sticky streaks, it may be a fragment of the endometrial lining that is shed periodically. This is considered normal by Western medicine, but for Chinese medicine it is considered to be caused by excessive dampness in the body and needs to be treated. If the sticky strips inside the menstrual period are too large, it may be caused by a medical condition. It is best to take medication to regulate menstruation, such as Wuji Bai Feng Pills. Do not touch cold and raw food before and after menstruation, otherwise it is likely to lead to cold into the body causing black color and blood clots in menstruation. You should first observe your condition when you have sticky stripes in your menstruation. If you have other abnormal symptoms or if the sticky stripes are too large, it means that treatment is needed.
