Honeysuckle is cold in nature and sweet in taste, and it belongs to the lung, heart and stomach meridians. Its core functions are to clear heat, detoxify and disperse wind-heat. It can not only clear and dissolve internal heat toxins, but also treat abscesses, furuncles, sore throat and other heat toxin syndromes. It can also disperse wind-heat from the outside and relieve the initial symptoms of warm diseases such as fever, headache and thirst. Modern pharmacology has confirmed that it has broad-spectrum antibacterial and antiviral effects and is often used for the prevention and treatment of influenza and the regulation of inflammation. However, those with weak spleen and stomach and cold constitution should use it with caution.
