Manufacturing Tinctures

Overview of Manufacturing Tinctures

Introduction to Tinctures

  • Tinctures are concentrated herbal extracts made using alcohol as a solvent.

  • Today’s focus is on preparing dried ginger tincture.

  • Tinctures can vary in strength, typically expressed as drug extract ratios (e.g., 1:10, 1:5).

Materials Used

  • Dried Ginger: Chosen for its use in pastilles.

  • Ethanol Absolute (99.8%): The pure form of alcohol used in tincture preparation, considered 100% for calculations despite natural impurities.

Legal and Safety Considerations

  • Alcohol extraction requires adherence to regulations:

    • Needs to be documented in an alcohol register.

    • Every use of alcohol must be recorded, including the amount, purpose, and date.

Preparation of Alcohol Solution

  • To create a vodka-like mixture:

    • 40% Alcohol Solution: Mix 40mL of ethanol with 60mL of distilled or filtered water.

    • Exothermic reaction upon mixing creates slight warmth.

Making the Dried Ginger Tincture

  • Initial Extraction:

    • Ratios: Start with a 1:10 dilution - 10g of dried ginger to 100mL of 40% alcohol.

    • The first maceration period is 2 weeks.

    • Shake daily for optimal extraction.

  • Double Maceration Method:

    • After initial extraction, strain and measure the volume of liquid obtained (e.g., 83mL).

    • Use 10% additional herb weight for a second maceration (8.3g for 83mL of tincture) to achieve a 1:5 dilution.

  • Container Considerations:

    • Use glass jars with tight-sealing lids (metal rusts, risk of contamination).

    • Label jars with:

      • Plant name and part

      • Weight of herbal material

      • Volume and percentage of menstruum

      • Date of preparation

Environmental Factors

  • Extraction time can vary based on ambient temperature:

    • Warmer environments speed up the process.

    • Cold environments may require extended extraction times.

Tincture Comparison: Ginger vs. Calendula

  • Dried Ginger: Denser, woody; allows for easier extraction and double maceration without significant loss.

  • Calendula: Softer, lighter; challenges in achieving strong tincture without multiple macerations due to density and volume.

  • Required additional volume of menstruum indicates the need for a larger jar or more herbs.

Formulation Calculations

  • Key formula for calculating tincture concentrations and dilutions:

    • If crafting a tincture with a desired strength, use the formula:

      • A (Desired volume) x B (Desired concentration) / C (Current concentration) = volume to draw from.

  • Example Calculation:

    • To create 100mL of 25% alcohol from 38% vodka:

      • Draw 66mL vodka and add 34mL water to reach desired concentration.

Conclusion

  • Utilize accurate measurements and methods in herbal preparations to ensure efficacy in final tincture products.

  • Understanding tincture preparation, especially ratios and extraction methods, is essential for crafting effective herbal remedies.
