What Are Herbal Infusions?
When you hear the term herbal Infusions in herbalism, it is referring to 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. Think…drinking a cup of tea.
Herbal teas (or tisanes) can be thought of as weak infusions, while true infusions are sometimes called “long infusions” to distinguish them from teas or tisanes.
An herbal infusion is the simplest way to prepare the more delicate aerial parts of plants, especially their leaves and flowers. For herbal infusions you can use a single herb or a combination of herbs. I always have fun experimenting with combinations of herbs and have come up with some very tasty medicinal brews.
What is a Long Herbal Infusion?
Long herbal infusions refer to the process of soaking plant material for significant lengths of time in order to draw out as much of its medicinal properties as possible.
The vitamin content of herbs has been studied to determine if longer soaks draw out more vitamins than short soaks.
What scientists found was that it takes at least four hours of soaking to extract a significant amount of vitamins and minerals into the water, and even longer (up to 8 hours) for roots or tougher plant material.
If, for example, you make a cup of nettle tea (1-2 teaspoons steeped in hot water for ten minutes), you would get about 5-10 mg of calcium, but if you make a cup of nettle long infusion (1 oz. steeped in 1 quart hot water for a minimum of four hours), you will get over 200 mg of calcium per cup. And not just the calcium, but all the nutritional cofactors necessary to effectively assimilate calcium, because calcium by itself is not well utilized by the body.
Note: It is important to recognize that not all herbs should be infused for long periods of time, as this can make some herbs unpalatable.
Long herbal infusions make for wonderful summer brews. I don’t know about you, but I love a nice glass of iced tea in the summer months, and long infusions are ideal for this. I love making sun tea, moon tea, or just letting herbs soak in water on my countertop over night. I’ll strain these out the following day, add a bit of lemon, honey or even an ice cube or two, and sip all day long.

Cold Infusion Method
Place 1 oz. of herbs tied in a muslin bag in a jar. Add 32 oz. of water. If dried herbs are used, dampen the herbs before infusing. Secure the bundle or herbs so that the bag floats in the top part of the water.
This method allows clear water to flow through the tea bag, while the suffused water with herbal extractives is circulating downward. This “circulatory displacement” will then force the clear water back to the top of the jar where the herbs are floating.
After one or two nights, squeeze the bag of herbs into the tea. Some go by the 32 oz. of water, but some people use less because they like a stronger infusion. You can go by your taste.
