The discovered vial at the construction site was 2 tbsp (30 mL), which means that the elixir was quite bitter to the taste, which most likely meant that the people who tried it only administered one drop at a time, by mouth.
In the area where the elixir was unearthed, hundreds more bottles from 2 centuries ago were found. In the past, there was a music hall and lounge in that place.
