3Ren Dong Teng - Honeysuckle Stem - Caulis Lonicerae

Ren Dong Teng (Honeysuckle Stem) is a cold, sweet herb in Traditional Chinese Medicine (TCM) known for clearing heat, resolving toxicity, and soothing the channels to relieve pain. It is derived from the stem of Lonicera japonica and shares similar heat-clearing and toxin-resolving properties with Jin Yin Hua (Honeysuckle Flower), but with a stronger focus on unblocking channels and alleviating pain from wind-damp obstruction. Ren Dong Teng is often used for sores, abscesses, sore throat, and fever from heat-toxin invasion, as well as joint pain and stiffness from wind-damp-heat bi syndrome. Its dual action of detoxifying and promoting circulation makes it a valuable herb for both infectious and inflammatory conditions.
