Botanical Description

Lonicera japonica, Japanese honeysuckle, is a vigorous, semi-evergreen woody climbing vine of the family Caprifoliaceae, native to East Asia and widely naturalized elsewhere. The slender, twining stems are pubescent when young and become hollow and woody with age, climbing to 6 meters or more over trees, fences, and shrubs. Leaves are opposite, ovate to oblong, 3 to 8 cm long, entire and softly hairy beneath. Fragrant tubular flowers are borne in axillary pairs, opening white and aging to yellow over one to two days; the corolla is bilabiate with a long tube. Small purple-black berries follow in late summer. The slender vining stem with attached leaves, collected in autumn or winter, is the part used as Ren Dong Teng.

Cultural & Historical Context

Traditional Chinese Uses

Ren Dong Teng (honeysuckle vine, lonicera stem) is a cool herb that clears Heat toxin and opens the channels and collaterals. Its Heat-clearing action is applied for febrile illness and inflammatory conditions similar to its flowers (Jin Yin Hua), while its channel-opening quality makes it additionally useful for Wind-Hot bi syndrome โ€” arthritis and joint pain with heat, redness, and swelling. It is gentle and can be taken in larger doses for acute inflammatory joint conditions.
