有汽涼茶是否可行?

I will answer it in english.

Soft drink have gas becuase the producer pump carbon dioxide (二氧化碳) into the drink. Carbon dioxide will ' dissolve ' in the solution and form carbonic acid (碳酸; H2CO3) which is a weak acid. so the drink is slightly acidic (酸性) (pH(酸鹼度)<7).

The change of pH from neutral (pH 7) could affect the drug properties by either enhance of reduce the drug function. Without any further experiments, it is difficult to conclude that how the drug property will change. However, it should not be tried directly on human as it is dangerous.

有汽涼茶，最近有新出品，香港製造，飲過，超正，好過引。我見Ozakka有得賣。

傳統的涼荼 - 加汽 - 我相信自己接受不了
