Can Lysimachia christinae Hance (Goldsword) be steeped in water for drinking?

Lysimachiae Herba (Guangdong金钱草) can generally be consumed as an infusion, but it is important to follow medical advice and consume it appropriately.

For healthy adults without specific health concerns, moderate consumption of Lysimachiae Herba infusion is generally considered safe. This herb has a sweet and salty taste with a slightly cold nature, affecting the liver, gallbladder, kidney, and bladder meridians. It is known for clearing heat and dampness, detoxifying, reducing swelling, promoting diuresis, and relieving urinary discomfort. It is commonly used for the prevention and adjunctive treatment of urinary tract stones and diseases such as cholecystitis. For individuals experiencing mild urinary tract infections or biliary discomfort, moderate consumption of Lysimachiae Herba infusion may help alleviate symptoms.

However, long-term and excessive consumption should be avoided. Lysimachiae Herba is a cold-natured herb, and prolonged or excessive use may increase internal coldness in the body, potentially causing symptoms of cold constitution and easily damaging body fluids and vital energy. Individuals with cold constitution or qi deficiency and physical weakness should consume Lysimachiae Herba infusion cautiously to avoid harming their health. Due to its diuretic properties, frequent and excessive consumption by healthy individuals may lead to increased frequency of urination.

Before deciding to use Lysimachiae Herba as an infusion, it is advisable to consult a physician or a traditional Chinese medicine practitioner, especially for individuals with chronic diseases, those currently taking other medications, or those in special physiological stages.
