Can I eat fermented rice (Laozao) during my menstrual period?
It is generally safe to consume sweet fermented rice (Laozao) during menstruation, and moderate consumption is recommended.

Laozao is a fermented food containing a certain amount of alcohol and sugar, and it is also rich in B-complex vitamins and yeast. For individuals with good physical condition, no special diseases or allergy history, moderate consumption of Laozao generally does not negatively affect the menstrual cycle. The nutrients in Laozao can help relieve menstrual fatigue and provide energy. Moderate intake of Laozao may help improve blood circulation, and for some people, it might help alleviate dysmenorrhea.
Laozao has warming and nourishing properties that can warm the uterus and dispel cold. For women with a cold constitution and poor menstrual blood flow, moderate consumption of Laozao can help promote uterine blood circulation, alleviate dysmenorrhea symptoms, and facilitate the discharge of menstrual blood. Although Laozao offers certain benefits for women during their menstrual period, it should still be consumed in moderation. Excessive alcohol intake may have adverse effects on the body, such as increasing the burden on the liver.
Women should aim to maintain a diverse diet during menstruation and avoid consuming overly spicy, cold, or blood-activating foods to prevent menstrual irregularities.
