Primary Actions

Clears heat and resolves toxin - Shui Yang Mei is used in regional practice for inflamed sores, boils, weeping skin lesions, and other heat-toxin presentations affecting the skin and superficial tissues.
Disperses blood stasis and relieves pain - the fruit line is applied for bruising, sprains, and traumatic swelling when minor bleeding and fixed pain need both cleansing and movement.
Stops minor bleeding and assists topical wound care - traditional use includes pounded or decocted preparations for traumatic bleeding and irritated skin eruptions.

Topical wash or poultice combinations with heat-clearing herbs such as Ku Shen or Huang Bai - used in regional external practice for eczema, boils, and damp-heat skin irritation.
Traumatic-injury powders and washes paired with blood-moving herbs such as San Qi - folk-style use when bruising, swelling, and minor bleeding occur together.

TCM Wiki describes Shui Yang Mei as bitter, astringent, and cool, entering the Lung and Large Intestine channels to clear heat, remove toxicity, dissipate blood stasis, and alleviate pain.
Regional Chinese herb references also preserve the practical point that Shui Yang Mei is commonly used externally, which helps explain why modern monographs often center on wounds, eczema, and sores.
