beta-escin and Pruritus

To observe the clinical effect of escin on patients with cutaneous pruritus caused by blood stasis and wind-dryness and to prove the theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood" in traditional Chinese medicine (TCM).. Fifty-one patients were randomly divided into escin-treated group (n=30) and loratadine-treated group (n=21). The patients in the escin-treated group were treated with escin for 4 weeks (300 mg, b.i.d.), and the patients in the loratadine-treated group were treated with loratadine (10 mg, q.d.). Symptom score reducing index (SSRI) was used to assess the pruritus degree, lesion range and lesion shape before the treatment, 2 weeks and 4 weeks after the treatment, respectively.. Two weeks after the treatment, the effective rate of the escin-treated group was 63.3%, and the effective rate of the loratadine-treated group was 67.0%. Four weeks after the treatment, the effective rates were 86.7% and 80.0% in escin- and loratadine-treated groups respectively. There was no statistical difference in total scores of SSRI in two groups (P>0.05), and the scores of pruritus degree and lesion shape also had no statistical difference (P>0.05), while the score of lesion range of the escin-treated group was lower than that of the loratadine-treated group (P<0.05).. Escin has satisfactory effect in treating pruritus caused by blood stasis and wind-dryness. The study confirms the TCM theory that "wind should be treated by regulating blood disorder, and wind disappears after activating blood".
