Extraction process:
1. Put exactly 25 ml of water for each 1 packet of (il nome del prodotto non lo metto per sicurezza) (no more than that!) in a small glass container.
A tea spoon is 5 ml and a table spoon is 15 ml, so 25 ml would be 2 tea spoons + 1 table spoon of water. Or just use a syringe/graduated cylinder/liquid medicine cups to measure out the exact amount, because spoons may vary slightly.
2. Put the contents of the packet in the water.
3. Stirr gently and leave for 10 minutes.
4. After that time, white pieces of benzydamnine should be simply floating on top of the solution. It should look like tiny white pieces of a pencil eraser.
5. Take another glass container and place a thin paper towel/toilet paper/one side of a tea bag/blotting paper/another thin filtering paper (but not a coffe filter) over the top.
6. Carefully and slowly pour the solution that you previously set aside for 10 minutes through the filter into that 2nd glass.
7. The white residue should be left on the filter. This is pure benzydamine.
8. Set it aside for about 10 minutes and let it dry, unless you wish to swallow the wet benzydamine with the filtering paper...
9. When it is dry, one could carefully take it off and either put it in an empty medicine/pill shell, ingest it in some creative way, store, etc.
