Can I take Banlangen during my menstrual period?

Isatis root (Banlangen) is commonly available in granule form. It is generally not recommended to take Banlangen during menstruation. However, if symptoms such as wind-heat common cold that match Banlangen's indications occur, it may be cautiously used under a doctor's guidance. Detailed explanation is as follows:

Banlangen has a bitter and cold nature and functions to clear heat, detoxify, cool the blood, and soothe the throat. It is commonly used to alleviate symptoms such as wind-heat common cold and sore throat. During menstruation, women's bodies tend to be relatively weak and their blood and qi circulation changes. Taking Banlangen, which has a cold nature, during this period may negatively affect menstruation. Women with a constitution prone to coldness or those who typically experience cold hands and feet and significant menstrual discomfort may experience cold invasion after taking Banlangen, potentially causing or worsening dysmenorrhea, poor menstrual flow, and even reduced menstrual volume or shortened menstrual period.

If a woman develops a wind-heat common cold during her menstrual period and experiences symptoms that match Banlangen's indications, it does not necessarily mean she must completely avoid taking it. In such cases, Banlangen can be appropriately used under the guidance of a doctor. The doctor will make a comprehensive assessment on whether Banlangen is suitable based on the woman's specific physical condition, severity of symptoms, and other factors, and will provide appropriate dosage and course of treatment recommendations.

During menstruation, besides medication, it is also important to rest adequately, maintain healthy eating habits, and avoid consuming cold or raw foods to support overall health.
