Smilax glabra promotes water, kapok clears damp-heat in large intestine, and radix rehmanniae clears heat and cools blood to produce fluid. This prescription mainly uses Smilax glabra and kapok to eliminate dampness, and adds radix rehmanniae to prevent dampness from damaging yin. From this point of view, although there are few drugs, the prescription is more reasonable.

However, this prescription is only suitable for the treatment of acne with damp heat and blood heat. It is not effective for acne of stomach cold type, lung and stomach heat accumulation type and phlegm and blood stasis type.

Therefore, it is necessary to distinguish the types of acne when using it.
