My 8 year old son had a cough for a few weeks, which was progressively intensifying - started around the time of the wild fires. He drank 1L of this 2 days ago while at his outdoor summer camp and hasn't coughed since. Thank you.
我 8 歲的兒子咳嗽了幾個星期，而且症狀逐漸加劇——大約是在野火會發生時開始的。兩天前，他在戶外夏令營時喝了1L，此後就沒有咳嗽過。謝謝。
