What are the benefits and effects of Cuscuta chinensis?

Cuscuta, as a traditional Chinese medicine, has the effects of tonifying the liver and kidneys, consolidating semen and urine, and preventing random leakage. It can be used in the treatment of conditions such as insufficiency of the liver and kidneys, lumbar and knee soreness, and fetal leakage due to kidney deficiency (a small amount of vaginal bleeding that occurs in the early stages of pregnancy).
The medicinal source of Cuscuta is the dried mature seeds of Cuscuta sinensis or Cuscuta chinensis of the family Cuscutaceae, which is flat in nature, with the effects of tonifying the liver and kidney, consolidating the essence and shrinking urine, tranquilizing the fetus, brightening the eyes, stopping diarrhea, and eliminating the wind and expectorating the spots when used externally, which is helpful in improving or treating the deficiency of the liver and kidney, soreness of the lumbar and knee, impotence and spermatorrhea, renal deficiency with fetal leakage, fetal restlessness, faintness of the eyes and tinnitus, and deficiency of spleen and kidney and diarrhea, among other diseases.
It should be noted that, although Cuscuta chinensis is a tonic product, it is partial to tonifying yang, so it is not suitable for people with yin deficiency and fire, dry stools, and short and red urine (small amount of urine with dark yellow color). In addition, it is recommended to use Chinese herbs under the guidance of a Chinese medicine practitioner to identify the symptoms.
