My BB also very serious, after trying 金銀花白菊花, no big change. After seeing several doctors and United Christian Hospital, they gave us "1% hydrocortisone" cream and the situation is much better now. Actually, you can buy it from Mannings or pharmacy store. The one I bought "Egocort Cream 1%" by "Ego" (Green and white packing). Make sure to stop using it when the situation being recovered.
