Recently the streets of Taipei have been festooned with signs posted by the sellers of guiling paste, touting its success in curing chronic sore and hoarse throats as well as its salubrious effects on the liver The paste, made from turtle shell, was originally a food used in Guangdong and Guangxi. In Hong Kong it is sold at stands like those that sell xiancao herbal jelly in Taiwan.
近來台北街頭出現不少標榜可治聲啞喉炎、補肝益氣的「龜苓膏」專賣店。龜苓膏原本是兩廣的地方性食品；在香港，它正如台灣街道上的仙草攤一般，酷熱天，坐下來吃上一碗，清涼又消暑。
