Infusion

Best For

Infusions are most effective for:

• Leaves

• Flowers

• Soft aerial parts

• Aromatic herbs

• Nutrient-rich herbs

They are especially useful when gentle extraction and immediate use are desired.

Appearance & Character

A well-made infusion typically shows:

• Color reflective of the herb (light to deep depending on plant)

• Clear to slightly cloudy liquid

• Mild to strong herbal aroma

• Light to moderate body

The flavor varies widely depending on the plant, ranging from mild and floral to bitter or earthy.

Preparation

Infusions are simple and quick to prepare.

Basic method:

Place herbs in a cup or jar

Pour hot water over plant material

Cover to retain volatile compounds

Steep for 10–20 minutes (or longer for nutritive herbs)

Strain and use

Best practices:

• Cover while steeping

• Use appropriate herb-to-water ratios

• Use longer steep times for mineral-rich herbs (like nettle)

• Drink fresh when possible

Historical & Cultural Context

Infusions have been used across cultures for centuries as one of the most accessible forms of herbal preparation.

They represent a foundational method in herbal practice, allowing plant medicine to be prepared quickly using water, heat, and time.

Often associated with water-based preparations and gentle extraction methods, including:

Decoction

Syrup

Electuary

Oxymel

Hydrosol Use

These preparations are commonly used to support hydration, gentle extraction, and immediate use of plant materials.

What It Is

An infusion is created by pouring hot water over plant material and allowing it to steep, similar to making tea.

This method extracts primarily water-soluble compounds, making it ideal for herbs that release their properties easily without prolonged heat.

Infusions are typically used fresh and consumed shortly after preparation.

Infusion (Infusum)

An infusion is a water-based herbal preparation made by steeping plant material in hot water to extract its soluble constituents.

It is one of the most common and accessible methods in herbal practice, often used for leaves, flowers, and other delicate plant parts.

Infusions are valued for their simplicity, immediacy, and gentle extraction.

Solubility & Extraction Notes

Infusions extract primarily water-soluble compounds, including:

• Minerals

• Vitamins

• Tannins

• Mucilage (partially, depending on herb)

• Some flavonoids

They do not effectively extract:

• Resins

• Oils

• Most fat-soluble compounds

Because extraction is relatively gentle, infusions are best suited for less dense plant material.

Shelf Life

Infusions are not shelf-stable.

Typical range:

• Use within 12–24 hours

• Refrigerate if storing briefly

Discard if:

• Sour smell develops

• Cloudiness increases significantly

• Fermentation occurs

Safety Notes

Infusions are generally safe and widely used.

Important considerations include:

• Use appropriate herbs for intended purpose

• Be mindful of strength and quantity

• Use fresh, clean plant material
