Why Alcohol-Based Tinctures Work Best

At The Gumpii Apothecary, we were among the first to extract native Australian botanicals using alcohol (ethanol). This wasn't a trend we followed — it was a decision grounded in science.

Two Methods. Very Different Results.

Essential oils are produced through steam or hydrodistillation. This process captures volatile aromatic compounds — the monoterpenoids and sesquiterpenoids responsible for fragrance and some biological properties.

Alcohol extraction captures all of that — and significantly more.

What the Research Demonstrates

A peer-reviewed study of Wilga (Guioa parviflora) published in Acta Horticulturae found that solvent extraction revealed three distinct compound classes: monoterpenoids, sesquiterpenoids, and diterpenes — predominantly coumarins.

The coumarins were the highest abundance volatile components found in the solvent extract. They were completely absent from the essential oil.

Compound Class Found in Essential Oil Found in Alcohol Extract
Monoterpenoids Yes Yes
Sesquiterpenoids Yes Yes
Diterpenes (coumarins) No Yes

This is not a minor difference. All three compound classes captured through alcohol extraction are the subject of active scientific research into their biological activity. Steam distillation simply cannot deliver the same compound profile.

The Science Behind the Compounds

Emerging research has characterised over 113 natural sesquiterpenoids for their biological properties, with studies identifying mechanisms including modulation of key cellular signalling pathways and apoptosis-related proteins in malignant cells (He et al., 2023). Monoterpenoids and diterpenes are similarly the subject of ongoing investigation into their biological activity across multiple research institutions globally.

Broader Extraction Profile

Alcohol allows for:

  • Broad-spectrum compound extraction
  • Capture of both water-soluble and fat-soluble constituents
  • More complete representation of the plant

This results in a more concentrated and comprehensive extract.

Efficiency and Absorption

Tinctures are liquid extracts, which makes them:

  • Fast to absorb
  • Easy to dose
  • Flexible in use

Alcohol also acts as a preservative, maintaining stability of the extract over time.

Alcohol vs Other Extraction Methods

Alcohol extraction:
Broad-spectrum, high efficiency, concentrated — captures water-soluble and fat-soluble compounds including resins, alkaloids, essential oils, and phenolic compounds.

Apple cider vinegar extraction:
Captures acids, minerals, and water-soluble compounds. More suited to daily tonic use.

Capsules:
Contain whole plant material. Slower, less concentrated delivery.

In Your Routine

Alcohol-based tinctures can be used:

  • On their own
  • Alongside other herbal formulas
  • As part of a layered wellness approach

Our Position

We don't make claims based on tradition alone. We extract in alcohol because the science supports it — and because our customers deserve the most complete botanical profile available.
