Ophiopogon root

Ingredient Profile

Modern Research Perspective

Ophiopogon japonicus root contains steroidal saponins, homoisoflavonoids, polysaccharides, and other constituents. Cell and animal studies have examined cardiovascular, inflammatory, immune, metabolic, cough-related, and gastrointestinal mechanisms. These signals remain dependent on extract composition and experimental dose.

Clinical research exists but is often based on combined interventions or variable preparations. Evidence specific to a standardized single material remains insufficient to confirm disease treatment effects, and dose, interactions, and long-term safety need more rigorous assessment.

Traditional Function

In traditional Chinese medicine, Ophiopogon Root is sweet and slightly cold. It is used to nourish yin, generate body fluids, moisten the Lung, clear Heart heat, and calm irritability. Its use is interpreted according to dry cough, thirst, yin-fluid deficiency, or deficiency heat.
