Scientific Summary
Ophiopogon japonicus is a perennial herb whose tuberous root is used in traditional medicine. It is primarily used to moisten the lungs and relieve coughs, sore throats, and respiratory infections, and it has diuretic and anti‑inflammatory effects; it may cause stomach upset or interact with diuretics, so should be used under guidance if taken long term.
