Entada Seed and Stem Classic Formulas … Natural Herb Library

Primary Actions

Strengthens the middle and supports recovery from weakness ... many modern Chinese materia-medica summaries describe Ke Teng Zi Ren as helping poor appetite, low intake, and depleted post-illness states.
Dispels wind-damp and relieves pain ... traditional use extends to aching sinews, weak low back, and painful obstruction with a deficiency component.
Supports sinews and bones in regional practice ... the lane often sits between tonic seed use and tougher liana-stem use rather than belonging purely to one or the other.

Digestive-support and fatigue combinations ... a regional lane for weak appetite and undernourished states.
Wind-damp and low-back-pain pairings ... used when deficiency and pain overlap.
Sinew-and-bone support decoctions ... more common in regional practice than in famous national formulas.

Current Chinese herb summaries often describe Ke Teng Zi Ren as mildly bitter, cool, slightly toxic, and useful for strengthening digestion while relieving wind-damp pain.
This is not one of the major high-traffic canonical TCM seeds, so conservative documentation is more accurate than pretending there is a huge uniform formula tradition.
