Dark red menstrual blood may indicate conditions such as qi stagnation and blood stasis, kidney deficiency, and uterine coldness.

1. Qi Stagnation and Blood Stasis

Women with qi stagnation and blood stasis may experience menstrual blood with a purplish-red or dark red color, accompanied by blood clots, as well as symptoms such as obstructed menstrual flow and abdominal pain. Additionally, they may have irregular menstrual cycles with varying amounts of menstrual blood. The main focus of treatment is to promote blood circulation and regulate qi to relieve pain. Herbal medicine is often recommended for treating qi stagnation and blood stasis. Selecting herbs that nourish qi and blood, warm meridians, and promote the flow of qi and blood can effectively eliminate cold and dampness, strengthening qi, nourishing blood, warming meridians, dispelling cold, and promoting the flow of qi and blood. It is advisable to follow the doctor's instructions when choosing medication.

2. Kidney Deficiency

Women with kidney deficiency may have menstrual blood with a pale or dark red color, irregular menstrual cycles, scanty menstrual flow, as well as symptoms such as soreness and weakness in the waist and knees, heel pain, dizziness, tinnitus, and abdominal coldness. The main focus of treatment is to nourish the kidneys. Increasing the intake of foods that have kidney-tonifying effects or taking herbal medicine prescribed by a doctor to nourish the kidneys can help improve these symptoms.

3. Uterine Coldness

Uterine coldness is a common condition among women. It is primarily caused by qi stagnation and blood stasis. It can lead to dark menstrual blood with blood clots, scanty menstrual flow, and menstrual pain, which can have a significant impact on women's fertility. The main focus of treatment is to warm the uterus, dispel coldness, and warm meridians to promote the flow of qi and blood. Removing the coldness can harmonize qi and blood. Therefore, it is recommended to consume foods and medications that warm the uterus to regulate this condition.
