What is the difference between powder, 4:1, %, etc?
Whole herbs and extracts are both very different products.
Whole botanicals in some cases contain every part of a botanical including roots or stems while extract contains a specific botanical compound and is measured to a specific amount.
Extracts come with standards set by potency percentage so your order will always match what was advertised.
NutriCargo Whole Ingredients (do not have % or ration in their name)
A whole ingredient contains the entire botanical, including the roots, stem, flower etc.
Extracts contain specific compounds extracted from the botanical. These compounds are denoted by the “%” sign.
Herbal extracts are often “standardized” to contain a certain amount of a compound or active ingredient. Standardization ensures that every batch of a botanical extract contains the same amount of the advertised compound. For example, Acerola 10% may be standardized to 10% vitamin C. Every batch of that product will have at least 10% of that active compound.
NutriCargo Extract Ratios
Ratio extracts are denoted by the ratio in their product name. For example 4:1, 5:1, 10:1 etc.
If it’s a 4:1 extract, for example, that means that four parts of the original plant are going into one part of the final extract, making it a concentrated powder.
Think of it this way: Ratio of dry plant material (X) to final extract quantity(Y).
X : Y
Y = weight of dry plant material
X = weight or volume of extract (depending upon whether the extract is a solid/dry extract or a liquid extract)
The concept here is that the essential activity of the dry plant material (X) is found in the quantity of extract (Y). Or in other words, Y quantity of the extract is equivalent to X quantity of the dry plant.
For example, a botanical ingredient listed as a 4:1 extract means that 4 kg of raw herbs were extracted down to 1 kg of dried powdered extract.
