This question is a bit off topic, except that it touches on the
history of ethnobotany..

I have posted pictures of an Iranian manufactured liquid imported into
Australia. It is arranged on the shelves of a local shop along with
pomegranate syrup, sour cherry syrup, rosewater and lemon water.

However it doesn't have any of the properties of its companions on the
shelf. The liquid in the bottle is clear and tastes of virtually
nothing.

The sales assistant wasn't able to help in its identification.

One likely clue is the picture on the bottle of the catkins of pussy
willow. That is a species of the genus Salix. So my mind turns to old
uses of Salix bark as a predecessor of synthesised salicylic acid and
aspirin.

I wonder whether anybody on this group can advise me whether I should
apply it or drink it. If the latter, how much and when? Or should I
throw it away.
