Glycerites: Glycerine Tinctures

Glycerin Extracts: A Gentle and Effective Extraction Method

Understanding Glycerin Extracts aka Glycerites

Using glycerine in your maceration is a gentle and effective way to extract the beneficial compounds from herbs. Unlike alcohol-based tinctures, glycerites use vegetable glycerin as the menstruum, making them an excellent choice for those seeking an alcohol-free option. Glycerin is a sweet, syrupy liquid derived from plant oils, and it has the unique ability to both extract and preserve the active constituents of herbs.

Benefits of Glycerin Extracts

  1. Alcohol-Free: Ideal for individuals who are sensitive to or prefer to avoid alcohol.

  2. Sweet Taste: The natural sweetness of glycerin makes glycerites more palatable, especially for children and those with taste sensitivities.

  3. Gentle Extraction: Glycerin is a mild solvent, making it suitable for delicate herbs and constituents.

Glycerin Menstruum Properties

Glycerin is a humectant, meaning it attracts and retains moisture. It is amazing in topical applications for its skin soothing qualities. It effectively extracts water-soluble compounds, as well as some alcohol-soluble constituents, making it a versatile solvent for herbal preparations. Glycerin also acts as a preservative, extending the shelf life of the extract.

Glycerine has a very low smoke point so avoid heat when working with this menstruum.

Soluble Constituents:

  • Water-soluble compounds

  • Mucilage

  • Saponins

  • Tannins

  • Some alkaloids

Plant Parts Suitable for Glycerin Extraction

Glycerin extracts are best suited for fresh plant material, but dried herbs can also be used. Delicate flowers, leaves, and roots are ideal candidates for glycerites.

How to Prepare a Glycerin Extract

  1. Choose your plant material: Both fresh and dried herbs can be used. If using dried herbs, ensure they are finely chopped or powdered.

  2. Optional, Create a Glycerin Solution: Mix vegetable glycerin with distilled water in a ratio of 3:1 (three parts glycerin to one part water). I prefer to use undiluted glycerine for extracts using fresh plant material and dilute only when working with dried herbs.

  3. Mix Herbs and Glycerine: Place the plant material in a jar and cover it with the glycerin solution.

  4. Shake Daily: Seal the jar and shake it daily for 2-4 weeks to facilitate the extraction process.

  5. Strain and Store: After the extraction period, strain and press the plant material to obtain the glycerite. Store the extract in an amber or UV-resistant glass bottle to protect it from light.

Tips for Using Glycerin Extracts

  • Dosage: Glycerin extracts are typically taken in smaller doses compared to teas or infusions due to their concentrated nature.

  • Shelf Life: Glycerin extracts have a shelf life of about 1-2 years when stored properly.

  • Applications: Glycerites can be used internally or externally, depending on the herb and its properties.
