Mullein (Verbascum Thapsus) – Glycerine Herbal Extract dry cough • 1,000 mg mullein leaf in 1 ml • alcohol-free • vegan • 50 ml

Alcohol is an effective extraction medium in herbal processing. It is not added to remain in the final product, but to release substances from the plant that are more difficult to obtain with water or glycerin alone. It dissolves water-soluble components as well as some less polar compounds.

For some Botanicals For Life herbal extracts, a water and alcohol phase is combined to obtain a broad spectrum of substances from leaves and other plant parts. Once extraction is complete, the alcohol is gently evaporated in a vacuum and is no longer present in the finished product. The final herbal extract is then transferred into an alcohol-free carrier, specifically coconut glycerin and water.

With Mullein tea, the leaves are usually steeped in hot water. The resulting concentration depends on the amount of raw material, water volume, and steeping time, so the dose is not precisely defined. Capsules usually contain only finely ground leaves or a blend of herbs without prior liquid extraction.

This product is a 1:1 liquid extract of Mullein leaf that has undergone multi-stage extraction. 1 ml of extract corresponds to approximately 1 g of dried leaf, and the recommended daily dose is 20 drops. Both concentration and dosage are clearly defined and easier to compare with other forms.

After the extraction phase is complete, the alcohol is removed from the herbal extract under reduced pressure. Due to the vacuum, it can evaporate at a lower temperature than would be necessary with normal heating, thereby preserving sensitive plant components.

The alcohol thus fulfills its role in releasing substances from the herbs, but is no longer present in the finished product. The result is a concentrated, alcohol-free extract that is then transferred into plant-based glycerin from coconut and purified water.

Multi-stage extraction refers to a process where several extraction phases are combined to obtain substances from herbs – typically utilizing water and, for selected herbs, alcohol. Different groups of compounds react to different media: some are better released into water, others into alcohol.

For Mullein and other extracts, this means the plant material is not processed by a single simple infusion, but step-by-step to capture a wider spectrum of natural components. Detailed parameters (maceration length, media ratios) are part of the production know-how. The essential point is that it is a multi-stage prepared extract, not just a common infusion.

Glycerin acts as a carrier in the extract. It keeps the herbal extract in liquid form, allows for drop-by-drop dosing, and contributes to the product's stability without the presence of alcohol.

All Botanicals For Life extracts use plant-based glycerin from organic coconut, rather than generically labeled vegetable glycerin from various commodity oils. Information about the carrier's origin is important: it is clear which raw material the medium comes from, and glycerin also has a naturally sweet taste.

The alcohol-free form itself does not mean the extract is weaker. The final concentration is primarily determined by the extraction method and the ratio in which the raw material is converted into liquid form. Alcohol may be an effective means of releasing certain substances during production, but its presence in the final carrier does not dictate the extract's potency.

The difference between a classic tincture and this product lies mainly in the form. An alcohol tincture keeps alcohol as the carrier, whereas here, it is removed after extraction and the extract is transferred into coconut glycerin and water. A 1:1 ratio means that 1 ml of finished extract corresponds to approximately 1 g of dried Mullein leaf. Potency can therefore be judged by the clearly defined concentration, not by whether the carrier is alcohol-based.

With herbal extracts, it is practical to monitor the concentration, not just whether the carrier is alcohol or alcohol-free. This is what the 1:1 ratio is for – technical information about the ratio of raw material to the final extract.

A 1:1 ratio means that 1 ml of the finished liquid extract corresponds to approximately 1 g of dried Mullein leaf. If the recommended daily dose is 20 drops (approx. 1 ml), you consume roughly the equivalent of 1 g of dried herb daily.

In the market, you often find extracts that do not state a ratio at all or use different ratios, such as 1:2 or 1:5. Generally, the higher the second number, the more diluted the extract is per unit volume. In a 1:5 ratio, 1 ml of extract corresponds to approximately 0.2 g of dry weight. The 1:1 figure is therefore crucial – it provides a clear and comparable parameter.

In contrast, Mullein tea depends on the leaf quantity, water volume, and steeping time, so few people can accurately estimate the actual concentration. With capsules, you usually know the weight of the ground leaf, but it is not an extract – the active substances have not been pre-extracted into a concentrated liquid form. With a 1:1 extract, the concentration is clearly defined and dosing is done by drops.

The brand specifies laboratory testing of finished herbal extract batches for common contaminants. They primarily monitor heavy metals, microbiological parameters (yeasts and molds), mycotoxins, and pesticide residues.

Heavy metals are related to the environment and soil where the plant grows. Yeasts and molds represent a typical contamination risk for plant raw materials, especially if they were improperly dried or stored. Mycotoxins are substances that certain molds can produce, which is why they are monitored separately. Pesticides are a common issue, particularly with herbs not grown in organic or agroecological systems.

Importantly, this evaluates not only the origin of the raw material but also the condition of the final extract sold in the bottle. The quality of herbal supplements consists of several steps: where the material comes from, how it was processed, and whether the final product meets purity requirements. Only the combination of this information provides a full picture of quality control.
