There's a reason that alcohol tinctures are so popular.
That reason being, alcohol + water absorbs most of the actives that we want out of a plant.
Your usual tincture is made either from fresh herb + 95 % alcohol; there, the water is in the plant. Or it's made from dried herb + 50-60 % alcohol; there, the water is in the liquid.
Either way, you get both alcohol- and watersoluble constituents out of the herb. (British tinctures are far weaker in alcohol, though.)
Here's a handy list for what constituents are pulled out into what kinds of liquids:
Alcohol: everything except minerals and trace elements. Mucilage is absorbed but is then split into simple carbs - so there's no mucilaginous action. Unless you do British-strength tinctures, which means very little alcohol to a lot of water.
Water: everything except resins.
Vinegar: minerals, trace elements, alkaloids
Glycerites: some minerals and trace elements, some alkaloids, some acids, some mucilage
Oil: oils, resins.
Syrup: oils, resins, sugars, mucilage.
If you have problems with alcohol you should substitute teas for your tinctures. They're not as handy (as in, you can't just take a cuppa while waiting for your bus), but you can always make a batch in the morning and carry a bottle of herbal tea with you.
You can also eat the plants as is; it's not all that practical for flowers and leaf, but it's easy to keep a tiny jar of dried root bits with you and just chew on a piece now and then.
Glycerites are nice and all that, but they're not even half as good as real live alcohol tinctures.
I'm sure I've forgotten one or the other menstruum (= liquid) and one or the other set of constituents pulled out into the ones I've listed. Feel free to add your comments.
