Hi Maria,
What a lovely gift! While fatty menstruums are great for tumeric, it can still be wonderfully extracted in vinegar yes. If you have alot and are thinking of doing multiple different medicines, it could be interesting to make an infused oil or ghee, a vinegar, (even) a tincture, dried, powdered (which could be used in milks/lattes or capsules), and maybe even a honey. This is a great opportunity to try them out and see how they work for you. Each type will have a slightly different energetic and action.
I hope you have alot of fun with it.
Warmly,
Benna
