It’s obtained by liquid pours over leaves, buds, flowers, fruits, drugs (fresh or dried), rich in flavors and fragrances, to extract the active principles you need; leave it to stand a ranging time from 3 minutes to 8 hours, then use the liquid after filtered, the ingredients are discarded . The infusion is the easiest way to extract the active principles from herbs and plants. However there are two ways to obtain infusion:

  • hot liquid infusion,
  • cold liquid infusion.

Hot liquid infusion.
Heat the chosen liquid at temperature ranging from 30°C to 90°C, pour it over one or more ingredients, from which you  want to extract the active principles. Leave it to stand  from 3 min to the time necessary for complete cooling or beyond (its use intended depending). It ‘s the most widely used method, because it’s easy and immediate. It can be obtained by:

  • hot water,
  • hot oil.

Infusion with hot water.
Heat the water to 95°C, pour over the herbs, cover and leave to stand a  ranging time from 3 to 10 minutes (chosen herbs depending); then filter all through a sieve with a mesh narrow then use it for external use, internal use or oral use. This method is quickly to extract the active principles of herbs; all herbs, fresh or dried,  used for infusion, which should be consumed within 24 hours.
External use.

  • It can be used for bath, sitz bath, foot bath, body wrap: pouring the filtered infusion in hot water.

Internal use.

  • Fumigation: it means the use of herbs active principles through the vapors; the infusion is poured into very hot water, inhaling the vapors, which should be hot but not boiling.
  • Inhalation: should be carried out with cold or lukewarm infusion.

Oral use.

  • The best doses for oral use are 2 or 3 cups of infusion per day, to be taken before, after or between meals, according to prescription. The oral use of active principles extracted from herbs and drugs by infusion, is recommended to relieve small ailments and to benefit from the  soothe and revitalize effects.

Infused with hot oil.
It’s obtained  pouring  500 ml oil (sunflower oil, olive oil, linseed oil …) in a heat-resistant container and add 250 grams dried herbs or 500 grams fresh herbs, then  cooked in a double boiler for about 3 hours over low heat and stirred occasionally. When the time’s up, strain all through cheesecloth or nylon sieve;  when all the oil is filtered, close the cloth and squeeze very well with a little wine-press or  potato masher, to extract any residual benefit from herbs; pour into dark glass bottles, date and label them. They can be preserved for 1 year.

This method is the best to extract the active principles from herbs with many leaves  Chickweed (Stellaria media), Nettle (Urtica dioica), Rosemary (Rosmarinus officinales), …).





There are many ways to use infusion with hot oil.

  • Massage: to alleviate the painful affections at the skeleton, joints, bruises, sprains, arthritis, osteoarthritis. The painful part is gently massaged until the oil is completely absorbed.

  • Cream: the oil thus obtained is used as a base for many creams preparations.

Cold liquid infusion.
Like by hot infusion, you get pouring cold liquid on herbs, drugs or a combination of herbs, chopped or pulverized, to extract all volatile substances, when the warmth should be dispersed them, or  you want to extract only a few components from the plant  (f.e.  Altea (Althaea officinalis) releases mucilage if infused in cold water). Leave the herbs or plants to stand in infusion from 30 minutes to several hours, ( by the herbs or plants depending), then strain and pour into dark glass bottles, date and label.
When the time infusion is long more than 8 hours, they aren’t call infusion but maceration and liquids used in this particular way,  may be much more than wine, vinegar, beer, alcool, oil, … .
