Xiong Qingzhen, a drone engineer in the central Chinese metropolis of Wuhan, spent more than two weeks in a makeshift hospital in February receiving treatment for Covid-19, the respiratory disease causing a global health crisis.
Every morning and evening, the 38-year-old was handed a bag of brown soup -- a traditional Chinese remedy blended from over 20 herbs, including ephedra, cinnamon twigs and licorice root.
But unlike most patients around him, Xiong was skeptical of its efficacy and refused to drink it.
