How to Make Milk Thistle Seed Extract
- 1). Place 3/4-cup full of milk thistle seeds in a blender or an herb grinder and process.
- 2). Pour the blended thistle seeds to a sterilized, pint-sized canning jar.
- 3). Pour 1 cup of 100 proof alcohol into the jar. Add 1 cup of water and stir to mix the ingredients.
- 4). Sit the canning jar lid on the jar with a canning ring and screw it on tightly. Place the jar in a cool and dark environment and leave it to set for three to five weeks. Shake the jar every day to make sure the thistle seeds stay saturated with liquid.
- 5). Combine 1 cup of 100 proof alcohol with 1 cup of water. Place this in a covered container and reserve it to pour into the jar if the liquid level drops or the seeds become exposed.
- 6). After three to five weeks, pour the mixture into a sieve or mesh strainer. Place small containers under the strainer to catch the thistle seed extract. Store the extract in the sealed containers.
