The Efficacy and Functions of Jinfeicao (Inula japonica)

　　Under normal circumstances, Jinfeicao (Inula Flower) is the dried aerial part of the Compositae plant species Inula japonica or Inula linearis. Jinfeicao has various functions and benefits, including clearing heat and detoxifying the body, relieving cough with phlegm-resolving effects, reducing swelling and alleviating pain, calming the mind and inducing tranquility, and enhancing physical fitness. Specific details are as follows:

　　1. Clearing Heat and Detoxification

　　Jinfeicao can clear heat and detoxify the body, showing excellent therapeutic effects on symptoms such as sore throat and stomatitis caused by heat toxicity. Its heat-clearing and detoxifying properties help eliminate inflammation within the body and promote recovery to health.

　　2. Relieving Cough and Resolving Phlegm

　　Jinfeicao has significant effects in relieving cough and resolving phlegm, especially suitable for treating coughing and excessive phlegm caused by colds due to wind-cold invasion. It helps to dilute phlegm and promote its expulsion, thereby alleviating cough symptoms.

　　3. Reducing Swelling and Alleviating Pain

　　Jinfeicao can reduce swelling and detoxify the body, demonstrating certain therapeutic effects on symptoms such as abscesses, carbuncles, toothache, and tongue swelling. This is attributed to its anti-inflammatory properties, as it contains antioxidants and anti-inflammatory substances that can effectively inhibit inflammatory responses.

　　4. Calming the Mind and Inducing Tranquility

　　Jinfeicao has a certain effect in calming the mind and stabilizing emotions, providing some relief for symptoms such as insomnia with vivid dreams and mental restlessness. It helps improve sleep quality, enabling more peaceful sleep.

　　5. Enhancing Physical Fitness

　　Long-term consumption of Jinfeicao can strengthen the constitution, improve the body's resistance, and help prevent colds and other diseases. This may be related to Jinfeicao's ability to regulate the human immune system.

　　During the period of taking Jinfeicao, one should avoid consuming it together with spicy and irritating foods, to prevent affecting the drug's efficacy or increasing the body's burden. Meanwhile, pregnant women, lactating women, and individuals with Yin deficiency with chronic cough or warm-dryness affecting the lungs should use it cautiously under the guidance of a physician.
