Shelf Life of Tinctures (Natural Skin Care/Medicine)

What is the shelf life of tinctures aka herbal extracts?

Some books say that tinctures aka herbal extracts have a shelf life of 2 years, but other books (which I consider better herbals) say 6 years or indefinitely. On the other hand, glycerites, a tincture made with glycerin instead of alcohol, have a shelf life of 1 year.
