Pour the alcohol or vinegar over the mullein until it is completely covered.
Seal the jar with the lid and set the mixture in a sunny spot to allow the infusion to get started quickly. (Not all tincture-makers do this, but I find it speeds up the “curing” process, so I don’t have to wait as long to use it.)
Shake the jar every day for four-six weeks.
When the tincture is ready, use cheesecloth to drain the tincture from the spent herbs and pour the liquid into amber glass dropper bottles. I use THESE.
Notes
Tinctures are most often extracted in alcohol because it’s the most potent solvent. Some herbs don’t release their medicinal properties in a less powerful solvent like apple cider vinegar. Alcohol is also a fantastic preservative, so alcohol-based tinctures have a practically indefinite shelf life if you store it in a cool, dark location. There’s no need to refrigerate an alcohol-based tincture.
If you want to use alcohol for tinctures to ensure you get the highest release of medicinal properties from the mullein but prefer a non-alcoholic product, just put the required drops of tincture into a small amount of hot water and allow it to sit for 5-10 minutes. The hot water will dissipate the alcohol content and leave only the herbal matter and water. This method is even safe for children.
Some people prefer to take a tincture by drinking it in a small amount of water or other liquid. This is especially helpful if the burning sensation you get from placing an alcohol-based tincture under your tongue is bothersome.
