Standardized Extracts

A standardized extract is a concentrated extract from a plant, in which the manufacturer declares the content of a specific active substance. It differs from regular dried herbs, where the content depends on the harvest, soil, and weather. In this category, you will find extracts in ratios from four to one up to one hundred to one, along with an explanation of what these numbers mean in practice.

How to read extract markings?

On the packaging of the extract, you will encounter two independent notations that can easily be confused. One refers to concentration, the other to standardization. Only together do they describe what is inside.

1. Extraction ratio. A notation of ten to one means that from ten kilograms of dried raw material, one kilogram of extract was produced. One hundred to one indicates a concentration ten times higher. However, the ratio alone does not indicate how much active substance is present in the product, as it depends on the quality of the starting raw material.

2. Standardization. This is a declaration such as thirty percent of alkaloids or twenty-four percent of flavonoids. It directly states how much active substance is contained in one gram of extract and is much more specific information than the ratio alone. A standardized extract provides a consistent dose from package to package.

3. Botanical name. Check the Latin name of the species, as common names can be ambiguous. Under one Polish name, different species with varying compositions can be hidden, and herbal producers rarely clarify this in the trade name.

4. Part of the plant. Roots, leaves, fruits, and bark contain different compounds. An extract from the root of kava kava is not the same as an extract from the above-ground parts, and the difference also concerns the safety profile.

5. Weight. Extracts are sold in small packages, usually five, ten, or twenty-five grams, precisely because they are concentrated. When purchasing, compare the price per gram, not per package.

What you will find in the standardized extracts category

The category includes extracts from single plants in powder form, packaged in small weights. You will find both popular species such as guarana, ginkgo biloba, or damiana, as well as raw materials less commonly found in Polish sales, such as akuamma, corydalis, or kava kava.

The same raw material usually appears in several weights, so you will see the same name multiple times on the list. Extracts in capsules and liquid form have been collected separately in the plant extracts category, and single-ingredient dried herbs can be found in the herbs category.

Extract, tincture, dried herb. How do they differ?

Dried herb is a dried plant, either whole or crushed. The content of active substances in it depends on the origin and harvesting conditions, so it can vary from batch to batch.

A tincture is made by extracting ingredients with alcohol and remains liquid. A dry extract follows the same principle taken further: the solvent is evaporated, leaving a powder. Therefore, the extract takes up significantly less space and requires a scale, as doses are measured in hundreds of milligrams, not teaspoons.

The solvent matters for the composition. Water extracts polar compounds, alcohol extracts resins and oils, and double extracts combine one with the other. The manufacturer provides this information on the label, and it is worth comparing when you are assessing two extracts from the same plant.

How to measure and store extracts

With concentrations around twenty-five to one, the difference between two hundred and four hundred milligrams is real, and such a difference cannot be assessed by eye. A jewelry scale with an accuracy of one hundredth of a gram is a basic tool for extracts, not a luxury.

Store powders in a sealed container, in a dry and dark place. Moisture clumps the extract and accelerates the degradation of ingredients, while light especially harms extracts rich in phenolic compounds. Keep them away from steam in the kitchen.

Safety and contraindications

A concentrated extract requires more caution than an infusion from dried herbs. Do not exceed the dose indicated by the manufacturer, do not combine several extracts at once without understanding, and do not use them during pregnancy or breastfeeding without consulting a doctor.

Some raw materials in this category interact with medications, particularly anticoagulants and mood-altering preparations. If you are taking medications regularly, consult the extract with a doctor or pharmacist before using it. Store products out of reach of children.

Frequently asked questions

What does the notation 25:1 mean?

It means that twenty-five kilograms of dried raw material were used to produce one kilogram of extract. However, the ratio alone does not indicate anything about the content of the active substance, as it also depends on the quality of the raw material and the extraction method. Therefore, the standardization declaration given in percentages is more valuable.

Does a higher ratio always mean a better product?

No, and this is a common misunderstanding. A higher concentration means a smaller dose is needed to obtain the same starting material, but it does not guarantee a higher content of the interesting compound. Compare extracts by the declared standardization, and treat the ratio as supplementary information. Two extracts with the same ratio can differ several times in the content of the interesting compound.

How to measure a dose of extract without a scale?

Practically, it cannot be done, and it is not worth trying. Volume measures fail because powders differ in bulk density, and a teaspoon of the same extract can weigh three hundred or six hundred milligrams. A scale with an accuracy of one hundredth of a gram costs less than one package of extract.

Can extracts be dissolved in water?

It depends on what solvent they were made with. Water extracts dissolve well, while alcohol extracts and those rich in resins often settle at the bottom or form a suspension. In practice, many people mix the powder with a small amount of fat or take it in a self-filling capsule.

How long can an opened extract be stored?

The manufacturer provides the expiration date on the packaging, which usually applies to the closed product. After opening, the tightness and humidity of the storage place determine it. A dry powder kept in a closed jar away from light retains its properties for a long time, but clumping or a change in smell are signals that it is time to replace it.
