Can consuming cooked Rehmannia root (Shu Di Huang) induce menstruation?
Consuming prepared rehmannia (Shu Di Huang) may, to some extent, stimulate menstruation, but it is not suitable for all patients with menstrual disorders. If physical discomfort occurs, it is recommended to seek medical attention at a hospital as soon as possible and follow the doctor's instructions for appropriate management.

Prepared rehmannia is known for its functions of nourishing the blood, enriching yin, and benefiting the essence and marrow. It can stimulate hormone secretion in women's bodies and regulate ovarian function. For symptoms such as menstrual irregularities or delayed menstruation caused by deficiency of both qi and blood or kidney deficiency, prepared rehmannia helps regulate the endocrine system through its effects of nourishing the liver and kidneys and replenishing qi and blood, which may indirectly promote menstruation.
However, it's important to note that prepared rehmannia, as a traditional Chinese medicine, primarily functions to nourish yin and benefit the kidneys and to enrich blood and essence. It is not directly used to induce menstruation and is not suitable for all cases of menstrual irregularities. For severe menstrual problems, such as polycystic ovary syndrome, using prepared rehmannia alone may not achieve the desired effect. Additionally, even for those patients who may benefit from its use, the specific treatment plan and dosage should be determined under the guidance of a physician. Overuse of prepared rehmannia may lead to adverse reactions, such as gastrointestinal discomfort.
Menstrual irregularities can be caused by various factors; therefore, treatment should consider multiple aspects comprehensively and adopt integrated therapeutic measures. In addition to drug therapy, attention should also be given to adjusting lifestyle habits, dietary nutrition, and other related factors.
