When it comes to extracting herbal properties, the choice of solvent is critical to achieving optimal results. While various solvents like vinegar, glycerine, and water can be used, alcohol is particularly effective for oral medicine formulations. Alcohol, including types like vodka and grain alcohol, is favoured for its ability to break down tough herbs and extract a wide range of compounds, including waxes, fats, resins, and volatile oils. However, its drying properties and potential for destruction of beneficial compounds during the extraction process are considerations that have led some to explore alternative methods, such as the use of oil-based extraction with an alcohol intermediary. The choice between alcohol and oil ultimately depends on the specific herbal properties being targeted and the intended use of the final product.

What You'll Learn
Alcohol is a popular choice for extracting herbal properties
The higher the alcohol percentage, the more plant juices are drawn out. 85–95% alcohol by volume is good for dissolving gums and resins, but it is not necessary for most plant material. This alcohol strength can produce a tincture that is hard to take and will also dehydrate the herbs if used for botanicals beyond gums and resins. 67.5–70% alcohol by volume is better for fresh, high-moisture herbs like lemon balm, berries, and aromatic roots.
When making a tincture, the jar should be filled halfway with herbal material, then alcohol is poured to the top to cover the plants completely. The plants should be finely chopped or ground to release their juices and expose more surface area. The jar should appear full, but the herbs should move freely when shaken. It is important to note that some roots and berries will swell more than others when reconstituted, so it is necessary to keep an eye on the tincture for the first two days and move to a bigger container if needed.
Alcohol is also used to extract essential oils from plants, such as the desirable aromatic compounds from vanilla bean pods. However, other solvents are also used for extraction, such as vinegar, glycerine, water, and carbon dioxide. The choice of solvent depends on the specific plant compounds being targeted and the intended use of the extract. For example, if the herbal extract is to be used orally for medicine formulations, a different solvent would be used than for isolating secondary plant compounds.

Oil-based extracts can be made via an alcohol intermediary method
The alcohol intermediary method is a popular method for creating herbal oil infusions. It is a two-step process that involves using alcohol to extract the herbal properties before infusing the herbs into a carrier oil. This method is known to increase the shelf life of the infused oils and create a more potent and effective product.
To start the process, dried herbs are macerated in high-proof alcohol, specifically 190-200 proof food-grade ethanol. This alcohol is known to enhance the extraction, potency, colour, and shelf life of the infusions. The herbs are allowed to soak and release their valuable constituents. After this, the alcohol is evaporated, and the herbs are infused into a carrier oil. This two-step process captures both alcohol- and oil-soluble compounds, resulting in a more complete and beneficial oil.
The alcohol intermediary method is relatively easy to master and can be used to create a variety of herbal oil infusions. It is a popular choice for those looking to enhance the efficacy and longevity of their infusions and work with a wider range of herbal constituents. This method is particularly useful for extracting properties from tough herbs such as berries and barks and is effective in extracting waxes, fats, resins, volatile oils, and alkaloids.
When choosing an alcohol for the intermediary method, it is important to consider the proof of the alcohol. Lower-proof alcohols contain more water, which can introduce excess moisture and reduce shelf life. High-proof, food-grade ethanol is recommended for the cleanest extraction. Additionally, dried herbs are preferred as they are less likely to spoil. If using fresh herbs, it is recommended to wilt them for a day or two to reduce moisture content before beginning the alcohol soak.
The alcohol intermediary method is a versatile and effective technique for creating herbal oil infusions. It offers a time-saving and potent alternative to traditional oil infusion methods, making it a popular choice for those looking to elevate their herbal preparation skills.

Isopropyl Alcohol and Ethanol are two popular solvents for oil extraction
When it comes to oil extraction, Isopropyl Alcohol and Ethanol are two popular solvents. However, the choice of solvent depends on the specific requirements and formula being used. Both solvents are not safe for consumption. Isopropyl Alcohol is a petroleum-based product with no additives and is a completely pure solvent. It is not recommended for consumption, but some customers claim that the solvent is flashed off when performed correctly. Ethanol, on the other hand, is a "grain alcohol" produced by fermenting grain. It is also not safe for consumption due to its bitter taste and potentially harmful effects.
Isopropyl Alcohol is considered a good alternative for soybean oil extraction, but its relatively high cost limits its large-scale use. Mixing it with less expensive solvents like ethanol can reduce costs and the mass transfer rate. In the case of soybean oil extraction, ethanol-rich mixtures are more suitable for obtaining high-yield extractions.
The choice between Isopropyl Alcohol and Ethanol for oil extraction depends on various factors. Some people prefer Isopropyl Alcohol due to its purity and the absence of the bitex component, while others may opt for Ethanol for its availability and potential ease of use.
The use of alcohol as a solvent for extracting herbal properties is a popular choice. Alcohol is effective in breaking down tough herbs and extracting their compounds, including waxes, fats, resins, volatile oils, and alkaloids. However, some people may find alcohol undesirable due to its drying properties and the potential for lye to destroy beneficial properties.
Overall, the decision between Isopropyl Alcohol and Ethanol for oil extraction depends on specific needs, availability, cost, and personal preferences. Both solvents have their advantages and considerations, and further research is always recommended to make an informed choice.
