Stimulating hair wash

Ok so this stimulating hair wash recipe comes from a Victorian beauty quiz (which I knew way too many answers to for some reason, btw).

It is a hair rinse, but I'd also probably drink it.
Is that the point? Was it a "hair rinse?" wink wink nudge nudge slash excuse for women to get drunk?

Who knows.

One recipe for stimulating hair wash: A handful each of rosemary leaves and box (eucalyptus) leaves, boiled in a quart of water until it becomes a pint; strain, and, when cold, add a gill (4 oz.) of rum. Pour into bottles and cork them down.

Where can I get some eucalyptus to try this out?

I already have rosemary from the food coop.
