患者的双小腿内外侧皮肤上呈片状散在分布着深褐色色素沉着斑，无高出皮肤，无痒、无痛只是感觉不好看、先是去西医院检查，结果是皮下毛细血管破裂引起的色素沉着，西医建议穿压力袜，患者穿一段时间后效果不明显就没穿，转而想试一试中医的治疗。
到本诊所后经过仔细的问诊、把脉结合患者的整体情况，建议内服中药治疗一段时间，半年后患者左小腿的色素沉着几乎完全消失，右小腿部的色素沉着减少了1/3。
Hyper-pigmentation in both legs for 2 years
The skin of the patient’s both legs was scattered in the form of dark brown pigmented patches on the inner and outer sides of the calf. There were no swelling, no itching, no pain, but it did not look good. First, he went to the Western Hospital for examination. Western doctor explained that the pigmentation was due to rupture of subcutaneous capillaries and recommended wearing compression stockings. Patients tried to wear for a short while but gave up. He wanted to try Chinese medicine treatment.
After careful consultation and combining the pulse with the overall condition of the patient, it was recommended to take Chinese medicine for a period of time. After half a year, the pigmentation on the left leg was almost absent, and the pigmentation on the right leg is reduced by 1/3.
