Résumé
We report a case of a 3-year-old girl who suffered from alopecia areata and was successfully treated with rokumigan modified formula. Initially, alopecia areata appeared on her left temporal region at the age of 3. The hair loss range had spread rapidly over the whole head. She visited our Kampo clinic because of insufficient effect of antiallergic drug. We prescribed her yokukansan, shimotsuto and juzentaihoto but the effect was insufficient. Finally, we thought this might be caused by kidney yin deficiency and liver blood deficiency because she had symptoms of pale white complexion, fine pulse, pale tongue with thin fur, and night sweating. Therefore, we administered rokumigan modified formula : rokumigan, tokiinshi and lycium fruit. Her hair began to grow after administering this formulation. There was not the re-hair loss during taking medicine for about 4 months. According to the traditional Chinese medicine, alopecia areata can be classified into 4 types : blood heat type, blood stasis type, dual deficiency type of yin and blood, dual deficiency type of qi and blood. We diagnosed this case as a dual deficiency type of yin and blood and selected rokumigan modified formula. Rokumigan is effective for various symptoms of kidney yin deficiency, and rokumigan modified formula may be useful for the treatment of infant alopecia areata.
