If you’re using fresh thyme, wash the herb and allow it to dry completely overnight.
Use a knife or mortar and pestle to crush up the fresh thyme. If you’re making a big batch, you can use a food processor to more quickly blitz a large amount. We do this to maximise the surface area of the thyme exposed to alcohol which will increase the amount of beneficial compounds the alcohol will extract from the plant.
Add the fresh herb to a clean glass jar. You want the jar to be about ¾ of the way full. If you’re using dried herbs, fill the jar ⅓ of the way full.
To start the extraction process, cover the herbs with alcohol completely. You want all of the plant material to be totally submerged in alcohol to avoid it becoming mouldy.
Put the lid on the jar and give it a good shake. Set it in a cool, dark place for 6-8 weeks. Date and label the tincture so you remember what it is and when you made it. Aim to shake it a few times a week to keep everything below the alcohol.
After 8 weeks, use cheesecloth or a fine mesh strainer to strain off the tincture. You can also use a coffee filter to get a finer strain - it will take a bit longer than the other options.
Use a small funnel to add the tincture to an amber glass dropper bottle. Label the tincture and it’s ready to use.
