Can Cuscuta seeds be steeped in water and consumed over a long period?

Generally, it is not recommended to drink water infused with Cuscuta seeds (Tu Si Zi) for a prolonged period. The detailed explanation is as follows:

Cuscuta seed is a traditional Chinese medicinal herb known for its functions of nourishing the liver and kidneys, consolidating essence and reducing urinary frequency, stabilizing pregnancy, improving vision, and relieving diarrhea. Drinking an appropriate amount of water infused with Cuscuta seeds can help alleviate symptoms such as soreness and weakness of the waist and knees, impotence, seminal emission, nocturnal enuresis, and frequent urination. Although Cuscuta seeds are neutral in nature, long-term and excessive consumption may lead to excessive internal nourishment, disrupting the body's yin-yang balance and causing symptoms of excessive internal heat, such as dry mouth, sore throat, irritability, and insomnia.

Long-term consumption of Cuscuta seed-infused water may increase the burden on the spleen and stomach, impairing their digestive functions and potentially leading to symptoms of spleen and stomach weakness, such as loss of appetite, abdominal distension, indigestion, and loose stools. Prolonged use may also lead to the body developing tolerance to the herb's effects, which not only prevents a continuous enhancement of its nourishing effects but may also reduce the body's ability to regulate internal organ functions due to over-reliance.

In daily life, if there is a need to consume Cuscuta seed-infused water, it is recommended to do so under the guidance of a physician, following the principle of moderation and closely monitoring the body's response. If any adverse symptoms occur, discontinue use immediately and seek medical attention. At the same time, maintaining a healthy lifestyle—including a balanced diet, moderate exercise, and sufficient sleep—can help support overall health.
