A herbal tea and an extract can start from the same plant and still differ in preparation, plant part and amount. A cup brewed with water does not give you a direct comparison with a spoonful of a labelled extract.
Compare the descriptions first
If a packet calls for steeping dried leaves in water, copy the plant name, part and brewing directions. For a liquid or dry extract, look for the plant part, preparation and declared amount per serving. If you find a ratio, check whether it describes starting herb to native extract and whether the label says what amount the ratio applies to.
| Field | Cup of tea | Extract pack |
|---|---|---|
| Plant material | Read the tea ingredients | Read the named plant and part |
| Preparation | The recipe or steeping instructions | The preparation and any solvent stated |
| Amount | What was brewed, if declared | The serving amount and ratio, if declared |
Give the comparison a purpose
You may be choosing a drink for its flavour or checking whether a research paper describes what you bought. In the second case, read the paper’s methods before comparing quantities. If you have been asked to bring your herbal products to an appointment, include the tea and the extract so your clinician can see both. The herbal powder and extract guide explains common label terms. The 10:1 ratio example shows when the arithmetic can be done.
