R. laevigata has a history of applications in
traditional Chinese medicine, with its initial documentation dating back to between 935 and 960 AD. Different components of the plant, notably the fruits (also known as Jin Ying Zi) and roots (Jin Ying Gen), have been utilized for their reported therapeutic properties. Within Chinese traditional medicine, the fruit has been traditionally associated with effects such as consolidating "
essence", reducing frequent urination, addressing
metrorrhagia, and acting as an
astringent in the intestines to manage diarrhea. The root has been traditionally used to strengthen "essence", intestinal astringent, and in the treatment of conditions such as
spermatorrhea,
enuresis,
dysentery, diarrhea,
metrorrhagia,
uterine prolapse,
hemorrhoids, and burns. Regional records in Chinese medicine additionally suggest its use for
hypospermia,
leucorrhea, pubic erections, chronic deficiency diarrhea, dysentery, stomach discomfort, children's enuresis, bruises, lumbar spinal discomfort, rheumatic joint pain, and uterine prolapse. Contemporary pharmacological investigations have explored the potential medicinal applications of
R. laevigata, with some studies indicating various biological activities. Both the fruit and root extracts have shown early indications of antioxidant, anti-inflammatory, antiviral, and anti-tumor effects in experimental models. Furthermore, observations suggest they may possess renal protective, immunomodulatory, lipid-lowering, cardiovascular protective, and bacteriostatic properties. Certain extracts have been investigated for their potential to address age-related urinary incontinence, support kidney function, reduce frequent night urination, and potentially influence gastrointestinal tract function. ==References==
