How to make herbal tinctures & infused oils

To extract the healing substances from herbs, solvents such as water, alcohol, glycerin, vinegars or vegetable oils are used. This kind of extractions are utilised as raw materials for the preparation of natural cosmetics and herbal remedies.

Tincture (alcohol extract)

Tinctures are alcohol based extracts. To make these herbal preparations high-proof alcohol (such as vodka) as solvent  is used to extract the essential compounds of herbs. This is a simple and efficient method appreciated by most herbalists since they can preserve this way herbal nutrients for a long - long time. Tinctures have an average shelf life of 2-5  years.

To make a tincture you will need:
  • herb(s) of choice, dry or fresh, finely chopped
  • high-proof alcohol (at least 80 proof). Good quality vodka works well. 
  • sterilized jar with lid 
  • fine strainer or muslin 
  • dark glass bottles for storing the tinctures. 
Put your herbs into the jar and add the alcohol. Generally, the ratio of fresh herbs to alcohol is 1:2 (1 part herbs to 2 parts alcohol). The ratio of dried herbs to alcohol is 1:4 or 1: 5 depending on the herb or the parts of the herb to be extracted. In case of woody parts and roots,  increase the alcohol rate.

Screw the lid on tightly, label your jars and let them steep in a cool, dark, dry place for at least 3 weeks giving the jars a little shake on a regular basis.

Strain using a fine strainer or muslin and store the tincture in dark glass labeled bottles.

Herbal infusion- Herbal tea 

For this simple preparation water is used as solvent to extract the active constituents of a herb. This kind of extractions can be used in creams, toners, lotions, herbal baths & soaks etc. Still, their self life is quite limited due to the (very) high water content. It is preferable to use them fresh in face masks, baths & soaks or as fresh toners preserving them for a couple of days in the fridge.

To make a herbal infusion you will need:
  • herb(s) of choice
  • a big clean jar with lid
  • hot water, preferable distilled 
Put 1 full tablespoon of chopped dried herbs in the jar and then add 250 ml of hot water. Place the lid to avoid essential oils' evaporation and let the herbs steep for at least 1 hour. For optimum results it's better to let the herbs steep for 6 to 8 hours. Strain the herbs using a fine strainer. Your infusion is ready to use.

Infused herbal oils

Another popular and efficient way to extract the healing properties of the herbs is to use vegetable oils as  solvents.  This way the oil soluble active ingredients as well as the scent of the herbs can be extracted. The infused herbal oils should not be confused with the essential oils.
The process for these preparations is quite similar to that of alcohol tincture; instead of alcohol a vegetable oil is used as solvent. It's important to use stable vegetable oils rich in vitamin E that do not go easily rancid.  The most common oils used for oily extractions are olive and almond oils.

To make an infused herbal oil you will need:
  • herb(s) of choice, dry and finely chopped
  • vegetable oil of choice, preferably cold pressed 
  • sterilized jar with lid 
  • cheesecloth or muslin 
  • dark glass bottles for storing the infused oils. 
The ratio to use is 1:4, 1 part of dried chopped herbs to 4 parts of vegetable oil.

Put the herb into the jar and cover it with the vegetable oil. Let the herbs steep for at least 3 weeks in a warm place shaking it from time to time. Warmth facilitates the active ingredients of the herbs to be released.

Strain the herbs using a fine cheesecloth or muslin and store it in dark glass bottles. Label them. Adding vitamin E at a rate of  0.2%  protects the infused oil from oxidation.

Herbal infused oils are used in massage oils, salves, balms, in healing creams and ointments.

Glycerin (Glycerol) Extracts

Glycerin is an alcohol in the form of a clear sweet thick liquid. It is a by-product of the saponification process and is obtained through the hydrolysis of vegetable or animal fats & oils. Glycerin is slightly antiseptic, humectant (it absorbs moisture) and once it is used dissolved with water it has soothing properties. It is a strong solvent, suitable for herbal extractions but it is milder than alcohol. It cannot dissolve resins or oil soluble substances.

Glycerin extracts are valuable in homemade cosmetics; they are beautifully incorporated into the water phase of creams & lotions combining the active herbal substances with the soothing properties of glycerin.

To make a glycerin extract you will need:
  • sterilized jar with lid
  • cheesecloth or muslin 
  • dark glass bottles for storing the extract
  • 2 parts herbs, dried and finely chopped 
  • 4 parts glycerin 
  • 4 parts distilled water
and for a more potent extract:
  • 2 parts herbs, dried and finely chopped 
  • 5 parts glycerin 
  • 3 parts distilled water
In a jar  mix glycerin and water; shake well to combine.
In a dark glass bottle put the herb and pour the liquid mixture over the herb to completely cover it. Label your bottle and let the herb steep for at least 3 weeks agitating regularly. Strain with cheesecloth, bottle, label and store your extract in a dark cool place.

If you want to make a glycerin extract using fresh herbs, the ratios are as following:
  • 4 parts herbs, fresh and finely chopped 
  • 6 parts glycerin 
  • 2 parts distilled water

A mythic cream: Galen's Cold cream

The first cosmetic cream in history was created by Galen, a Greek physician who was born in Pergamum (Asia Minor), studied in Greece and became the most famous doctor in the Roman Empire. His theories dominated European medicine for more than 1,500 years.
Since Galen was chief physician to the gladiator school in Pergamum, gaining much experience of treating wounds, he invented many therapeutic preparations and among them the famous Galen's cold cream (=ceratum refrigerans) which took this name due to its cooling effect in the skin once the water was evaporated.

Today, ceratum refrigerans  may seem as a primitive water-in-oil emulsion, still at that time it was a pioneer preparation that remained unchangeable for 15 centuries. 

Queen of Hungary Water, facial toner & light fragrance

In this renaissance recipe history and facts are conflicting with myths and legends. There is a noteworthy bibliography for this legendary preparation: each author proposes his/her own version! Queen of Hungary Water is considered to be the wold first alcoholic perfume but also an almost magical tonic, a youth elixir. 
Its name is connected with Queen Elisabeth of Hungary (1305-1381); the 72 year old queen  needed an elixir to cure her rheumatism and to give her back her lost beauty. There is a legend that the elixir was prepared by an alchemist of the royal court and that it was so effective that the 25 year old king of Poland asked her to marry him!!

For your eyes only! Anti-wrinkle Eye cream.

For my e-friend Eleftheria who asked for an efficient anti-wrinkle and easy to prepare eye cream! 

The key ingredient in this recipe is the Evening Primrose Oil (Oenothera biennis) which is very nourishing due to its high content in essential fatty acids such as gamma-linolenic acid. Essential fatty acids inhibit bacteria growth, fight infections and are anti-inflammatory. Evening primrose oil is ideal for the dry & sensitive skin area around the eyes.
