Worming - With Holding Period?

[cluckcluckluke]

O.K I have gotten a bottle of worming stuff from a friend it is just in a small water bottle and I have no idea of what it is, it has no info on. So what is the usual with holding period of a wormer. It goes in their water, so is taken orally.

Dont use it if you dont know what wormer it is or dosage; would you drink a medicine not knowing that info?
