Japanese honeysuckle flower concentrate supplies chlorogenic acid and luteolin in an absorbable form. People use it at the first sign of seasonal throat scratchiness or for brief immune defense.
Take it as a tea, tincture, or capsule. The extract absorbs faster than raw herb powder.
Short-term use only unless a practitioner says otherwise. Avoid it if you take blood thinners like warfarin, and skip it during pregnancy or breastfeeding.
