Introduction
Under normal circumstances, Peucedanum japonicum (Hanjianhu) has various effects and functions, including resolving phlegm and relieving cough, dispersing wind-heat, regulating qi and stomach function, promoting blood circulation to regulate menstruation, and treating traumatic injuries and fractures. The saponin components in Peucedanum japonicum have expectorant properties, which can dilute phlegm, promote its expulsion, and thereby alleviate coughing symptoms. This is particularly effective for treating symptoms such as excessive phlegm with cough and asthma, and chest tightness with discomfort.

Generally, Radix Peucedani (Hanshenhu) has various functions and benefits, including resolving phlegm and relieving cough, dispersing wind-heat, regulating qi and harmonizing the stomach, promoting blood circulation and regulating menstruation, as well as treating bruises, contusions, and fractures. The specific details are as follows:

1. Resolving Phlegm and Relieving Cough: The saponin components in Radix Peucedani have expectorant properties, helping to thin mucus, promote its expulsion, and thereby alleviate coughing. This is particularly effective for treating symptoms such as excessive phlegm with coughing and chest tightness.

2. Dispersing Wind-Heat: Radix Peucedani has the effect of relieving superficies and cold, as well as dispersing wind-heat from the lungs. It can relieve symptoms such as headache and sore throat caused by external wind-heat, making it suitable for treating wind-heat type colds.

3. Regulating Qi and Harmonizing the Stomach: The volatile oil component in Radix Peucedani can stimulate gastric juice secretion, increase appetite, and also relieve stomach discomfort such as bloating and pain. Therefore, it has certain therapeutic effects on stomach disorders like fullness and vomiting.

However, for severe bruises, contusions, or fractures, timely medical attention should be sought, following the doctor's instructions.

Before using Radix Peucedani, it is necessary to consult a doctor to ensure its safety and suitability. At the same time, the dosage must be strictly controlled, as excessive use may cause adverse reactions such as diarrhea.
