The Efficacy and Function of Cuscuta Seed
Generally, Cuscuta (Tu Si Zi) has functions and effects such as nourishing the liver and kidneys, consolidating essence and reducing urination, stabilizing pregnancy and improving vision, stopping diarrhea, regulating immunity, and antibacterial action. The specific details are as follows:
1. Nourish the liver and kidneys: Tu Si Zi enters the liver, kidney, and spleen meridians, and can moisten dryness, tonify deficiencies, balance yin and yang, and strengthen the kidneys. It significantly improves symptoms caused by liver and kidney deficiency, such as weakness and soreness in the lower back and knees, impotence, and seminal emission. Additionally, it treats kidney deficiency-related low back pain, often used together with Eucommia (Du Zhong) and Chinese Yam (Shan Yao).
2. Consolidate essence and reduce urination: Tu Si Zi nourishes both kidney yang and kidney yin, and has excellent effects in consolidating essence and reducing urination. It is used to treat symptoms such as frequent urination, bedwetting, urinary frequency, urgency, pain, and incontinence caused by kidney deficiency, often used together with Lycium (Gou Qi Zi) and Raspberry (Fu Pen Zi).
3. Stabilize pregnancy and improve vision: Tu Si Zi also helps stabilize pregnancy and improve vision. It treats symptoms such as fetal restlessness and vaginal bleeding during pregnancy, commonly used together with Prepared Rehmannia (Shu Di), Eucommia (Du Zhong), and Lycium (Gou Qi Zi). At the same time, it treats dim vision caused by liver and kidney deficiency, often combined with Prepared Rehmannia (Shu Di) and Plantago Seed (Che Qian Zi). Moreover, raw Cuscuta primarily nourishes the liver and improves vision and is clinically used to treat blurred vision.
4. Stop diarrhea: Tu Si Zi also has the effect of stopping diarrhea, treating loose stools and diarrhea caused by deficiency of both spleen and kidney, commonly used together with Codonopsis (Dang Shen), Atractylodes (Bai Zhu), and Chinese Yam (Shan Yao).
5. Immune regulation and antibacterial effects: Modern medical research shows that Tu Si Zi has immune-regulating properties. Its alcohol extract acts as an immunostimulant that enhances humoral immunity and phagocytic function. Additionally, it inhibits pathogenic microorganisms such as Staphylococcus aureus, Shigella flexneri, and Salmonella typhi.
When using Tu Si Zi for treatment, it must be done under the guidance of a physician. Self-medication should be avoided to prevent improper use that may harm health.
