How to use herbs
Generally, herbal products can be taken or applied up to three times a day.
The dosage and frequency will vary depending upon your state of health and the type of herbal product.
The elderly, the young and those that have a weakened state or are sensitive, may require a lower dose than the standard healthy adult.
The recommended dosage stated in our website, in reliable herbalist books or literature sources should be used as a guideline only.
There are many ways to use herbal products:
- Internally in the form of tinctures, teas, powders and capsules and
- Externally as infused oils, compresses and foot/hand baths.
- Tinctures and teas can also be added to cream, lotions or sprays for external use and natural skincare.
- Herbal products can be used beneficially in culinary doses in food, cordials, syrups and herbal teas.
The most used methods of herbal tinctures, infusions and teas
- Herbal tinctures
A tincture is a concentrated herbal liquid. It is made by combining fresh or dried herb with alcohol and water then leaving it to macerate for a specific amount of time.
This is then pressed and produces a liquid which contains the active constituents of the required herb. Tinctures come in varying strengths such as 1:5 25%, 1:10 60%.
For example, a 1:3 45% strength means that: one part (in weight) plant material is macerated with three times the amount (in volume) of alcohol and aqueous liquid which is called the ‘menstruum’. 45% of the menstruum is alcohol, the remaining 55% is water. Always check the recommended dose for each individual herbal tincture. Eoil offers single herbs herbal tinctures.
Our tinctures are made using organic grain alcohol - fermented wheat.
Please read the product page carefully, noting any allergens and dosage information and consult the information in this leaflet as a guide only. Please consult a healthcare professional if you have any questions.
Herbal tinctures may have a strong flavour that is not always palatable. The dose can be added to a cup of water to drink, which will dilute the taste.
Always keep well hydrated whilst taking a course of herbal remedies.
- Herbal infusions
An infusion uses either dried or fresh herbs and is made like a tea. It uses the soft part of plants like flowers, leaves and small berries or seeds. It can be made in a teapot, cafetière or tea ball. A standard infusion for one cup is a teaspoon of a single dried herb or herb blend. Add boiling water, preferably cover to avoid the loss of volatile oils. Leave to infuse for 5-10 minutes, strain and enjoy.
- Herbal decoctions
Decoctions are used for solid or woodier parts of the plant, like roots, bark and tough seeds or large berries where an infusion would not extract the properties sufficiently. The herbs are simmered in a covered pan for 10-15 minutes. A standard decoction is one teaspoon of dried herb per cup of water. Tip: you can make 3 cups at the same time and keep in a sealed, insulated container. This can be drunk hot or cold throughout the day. Do not store longer than one day to avoid bacterial growth.
