. When dry herbs were used to make the extract the ratio is commonly 1 part dried plant to 4 parts liquid, (alcohol and water). When fresh herbs are used the most common ratio is 1:1. This does not indicate the amount of that herb in the bottle, rather the ratio used in making the extract. Example: Dry herb strength: 1:4 means that the mixture used to produce the extract was 1 part dried plant and 4 parts liquid, (alcohol and water). This is not the same as an ingredients list which is also present on most commercial extracts.

 (referred to as an acetous tincture) and glycerin. These fluids are less effective in extracting a wide variety and quantity of plant compounds and have greatly lesser shelf life, but are desirable when alcohol needs to be avoided or in the few exceptions where the desired active ingredient of the plant is more dissoluble in acetic acid than ethanol. Non-ethanol alcohols are sometimes used for tinctures intended for external use, as they are not taxed and hence significantly cheaper to use when possible.
