This paper summarizes Professor AI Rudi's experience in the diagnosis and treatment of skin pruritus based on the "unity of restoring form， regulating

qi

， and harmonizing spirit"， employing internal herb

al medicine combined with external treatments. It is believed that the core pathogenesis of pruritus is the "imbalance of form，

qi

， and spirit"， with disturbed spirit as the onset， disordered

qi

as the key pathogenic factor， and physical changes as the manifestation of the disease. The treatment principle follows "restoring form-regulating

qi

-harmonizing spirit"， with a combination of internal and external therapies， and differentiation based on deficiency and excess. For excess conditions caused by pathogenic disturbances to the heart spirit， treatment is based on different patterns of wind-heat， damp-heat， and blood-heat， using Sangye （

Morus alba

）-Sangbaipi （

Morus alba cortex

）-Longchi （

Draconis os

） to disperse wind and clear heat， calm the spirit； Difuzi （

Kochia scoparia

）-Qinghao （

Artemisia annua

）-Tanxiang （

Santalum album

） to clear damp-heat and aromatically open the spirit； Mudanpi （

Paeonia suffruticosa

）-Chuanxiong （

Ligusticum chuanxiong

）-Shuiniujiao （

Bubalus bubalis cornua

） to cool the blood， activate circulation， and calm the spirit. For deficiency conditions caused by insufficient nourishment of the heart spirit， treatment is based on patterns of

qi

deficiency or blood deficiency， using Huangqi （

Astragalus membranaceus

）-Fuping （

Lemna minor

）-Wuweizi （

Schisandra chinensis

） to tonify the

qi

and stabilize the exterior； Heshouwu （

Polygonum multiflorum

）-Jili （

Tribulus terrestris

）-Shouwuteng （

Polygonum multiflorum vine

） to nourish the blood， moisten dryness， and calm the spirit. External treatments integrate traditional Chinese medicine therapies such as medicinal baths， gua sha， and ear acupuncture， with custom herbal wash formulas for restoring form， jojoba oil gua sha for regul

ating

qi

， and ear seed therapy using Wangbuliuxing （

Vaccaria segetalis

） for harmonizing the spirit， achieving a holistic treatment effect for form，

qi

， and spirit.
