Herbal infusions offer an easy method for consuming the oils and flavors from favorite herbs. Infusion is the process of steeping (soaking) herbs in water until the water absorbs the oils and flavors, then drinking the liquid for the taste or for the medicinal value. Herbal tea is a form of infusion, in that it is created by steeping herb leaves in hot water, but the resulting drink is rather weak since the steeping period is usually fairly short. True infusions typically use roots, shoots, leaves, and flowers of the plant, while teas typically use only the leaves in the steeping process; and true infusions require a considerably longer period of steeping. Herbal tea can be thought of as weak infusion, while true infusions are sometimes called "long infusions" to distinguish them from teas. 

For natural health enthusiasts, infusions offer a more natural way to ingest herbs, when compared to swallowing pills and tablets. For others, herbal infusions are simply a way to enjoy the taste of various herbs. Whatever the goal, you will find it quite easy to make herbal infusions. It is a process that requires time but minimal effort.

Herbs for Great-Tasting Infusions

Herbs most commonly used because they offer great-tasting infusions include chamomile, ginger, and any of the mints. 

It is important to remember that some herbs can be harmful if you consume too much, such as if the infusions are allowed to steep too long. Combining the wrong herbs can also lead to problems. For this reason, please do your research before making any infusion you intend to drink. It's best to follow recipes from trusted sources and pay attention to any warnings given.

Consult your physician or herbalist before drinking infusions.

How to Make an Herbal Infusion

Herbal infusions take very little time to prepare, but you will have to wait for the herbs to steep thoroughly. Be sure to follow the recommended times and measurements in your herbal infusion recipe.

In order to make an herbal infusion, you will need three things:

  • 1 tablespoon dried herb of your choice
  • 1 cup boiling hot water
  • Glass jar with a tight lid (make sure it is very clean)

The quantities of herbs and water can be increased proportionately to make a larger infusion if you wish. If you want to make 1 quart at a time, for example, this will require about 1 cup of dried herb and 1 quart of water. However, it's best to start with a small volume on your first infusion of any herb to avoid waste if you find you don't like it. 

While making the infusion, be sure to keep the jar covered at all times to contain the steam. The heat that's trapped inside is crucial to releasing those beneficial compounds in the herbs.

  1. Place the herbs in a glass container.
  2. Pour boiling water over the herbs so they are completely covered.
  3. Seal the jar with a tight-fitting lid to keep the steam and volatile oils from escaping.
  4. Allow the infusion to steep until the water cools to room temperature or for the time recommended by the infusion recipe. In general, roots and barks require the longest infusion (or a decoction) of about 8 hours. Leaves should be infused for a minimum of 4 hours, flowers for 2 hours, and seeds and fresh berries for at least 30 minutes.
  5. Strain the spent herbs out of the water using cheesecloth or a fine-mesh strainer (or both). Repeat if necessary to remove all of the herbs.
  6. The resulting liquid is called an infusion. Clean out the jar and pour the infusion back into it for storage. An infusion can be refrigerated for up to 48 hours. After this, it should be discarded. 

To avoid the straining, you can make a sachet to contain the herbs during the steeping process. Place the herbs inside a small piece of cheesecloth, tie it closed with a string, and place the bundle inside your jar of boiling water. You can even let the string hang over the side for easy removal. 

A Decoction: a Stronger Infusion

A stronger beverage, called a decoction, can be made by using roots, barks, dried berries, and other plant materials that require stronger, more prolonged heat in order to extract the oils.

To make a decoction, combine the herbs and water in a small saucepan. Cover with a lid and slowly bring to a simmer. Allow the mix to simmer gently for 20 to 45 minutes (or according to your recipe). Remove from the heat, strain, and pour the liquid into the storage jar.
