The Chinese Pond Turtle (Mauremys reevesii), known as "Guī Bǎn" (龟板) in Traditional Chinese Medicine (TCM), has a long history of use in China. It is considered a tonic, especially for nourishing "Yin" and strengthening the body after illness or childbirth. In the context of postpartum weakness, Guī Bǎn is traditionally included in herbal formulas intended to restore strength, replenish vital essence (Jing), and promote recovery. The shell, rather than the meat, is most often used, and is believed to nourish the liver and kidneys, strengthen bones, and enrich the blood.

There is little direct scientific evidence validating the efficacy of Chinese Pond Turtle for postpartum recovery. Most available data come from animal studies or in vitro experiments, focusing on immune modulation, anti-inflammatory, or anti-osteoporotic effects. However, these studies do not specifically address postpartum weakness. The use of Guī Bǎn for this purpose is therefore justified by centuries of traditional practice and anecdotal clinical experience rather than modern scientific validation.

In summary, the use of Chinese Pond Turtle for postpartum weakness is rooted in TCM tradition, supported by historical texts and common clinical practice in East Asia, but lacks robust scientific research directly supporting its effectiveness for this specific condition.
