Can I drink Banlangen during lactation?
Generally speaking, women can consume Banlangen (Isatis root) in moderation during lactation, but should follow medical advice. The detailed explanation is as follows:

Banlangen, as a commonly used traditional Chinese herb, has effects of clearing heat, detoxifying, cooling the blood, and relieving sore throat. It is generally considered relatively safe and typically does not cause significant negative effects on women who are breastfeeding or their infants. Banlangen is often used to treat symptoms such as fever due to external pathogens (wind-heat), sore throat, and has certain antiviral properties. During lactation, if a woman experiences mild cold symptoms such as sore throat, moderate use of Banlangen may help alleviate these symptoms. However, lactating women should also exercise caution when taking Banlangen, strictly follow the doctor's instructions or the dosage recommendations provided in the medication's instructions, and avoid excessive use.
In daily life, maintaining good lifestyle habits is important. Women who are breastfeeding should ensure adequate rest, avoid overexertion, maintain a regular schedule, and enhance their physical immunity.
