Limited Evidence

Honeysuckle flower is included in many traditional Chinese medicine formulas for fever and sore throat; modern controlled trials are limited.

How it works

The flower buds contain chlorogenic acid, luteolin glycosides, and iridoid glycosides with in vitro anti-inflammatory and antimicrobial activity. Lonicera japonica is a core ingredient in traditional formulas for upper respiratory and febrile illness. Modern clinical evidence is mostly from small studies and traditional formula research.

Dosage

Traditional decoction uses 6-15 g of dried flower buds per day. Extract products vary in concentration.

When and how to take it

No strict timing. Taken as tea or formula several times daily during acute illness in traditional use.
