Honeysuckle leaves are the dried leaves of Lonicera japonica, family Lonicera japonica, which can be infused into water for drinking, but the water is limited to precipitate medicinal ingredients. Honeysuckle leaves are sweet, light and cold in nature. It has the efficacy of dispelling wind, clearing heat and detoxifying, and is attributed to the lung, heart and stomach meridians. Honeysuckle leaves are used to treat wind-heat colds, coughs, sore throats, swollen eyes, carbuncles (a condition in which the lungs develop sores and pus ulcers are formed), carbuncles (red, swollen and painful breasts with milk discharged poorly, and ultimately pus-filled illnesses), dengtoxin (an acute infectious disease in which the reddening of the skin is seen as if it had been coated with pigment), and wet sores. Gold and Silver Lonicera is cold in nature, so it is contraindicated for those who have cold spleen and stomach (weak and cold spleen and stomach). Patients are advised not to take the drug on their own to avoid adverse reactions.
