Honeysuckle is mainly used for carbuncle, paralysis of the throat (pharynx red, swollen and painful, or dry, foreign body sensation, or pharyngeal itching, discomfort, difficulty in swallowing), dengtoxin (acute infectious diseases, visible skin red like paint), wind-heat colds, fever of warm diseases. Its adverse effects are not clear, and it is contraindicated for those with spleen and stomach deficiency (spleen and stomach weakness and cold) and qi deficiency sores and pus clearing.
