Decoction vs. Infusion — What's the Difference?
By Urooj Arif & Maham Liaqat — Updated on April 27, 2024
Decoction involves boiling plant material to extract its essence, suitable for harder substances like roots, while infusion is steeping material like tea leaves in hot water, ideal for more delicate parts.

Key Differences
Decoction is a method used primarily for extracting flavors, colors, and medicinal properties from tough and woody plant materials by boiling them. Whereas, infusion typically involves pouring hot water over plant materials and allowing them to steep, which preserves the delicate substances that might be destroyed by boiling.
Decoction is commonly used in traditional medicine to prepare remedies from hard substances such as roots, bark, and seeds which require more aggressive extraction methods. On the other hand, infusion is popular in making herbal teas, coffee, and other beverages from leaves, flowers, or aromatic herbs.
The process of decoction usually takes longer, as the plant materials need to simmer for an extended period to break down fully and release their active compounds. Whereas, infusion generally takes a few minutes, as prolonged exposure to hot water can lead to the release of bitter tannins, especially in tea.
Decoction can often result in a stronger, more concentrated flavor and medicinal properties, making it ideal for therapeutic uses. On the other hand, infusion is preferred for its lighter, more delicate flavors and is often consumed for enjoyment rather than strictly medicinal purposes.
Decoction requires more active involvement to ensure that the water does not evaporate too much and that the substances do not burn. Whereas, infusion is a more passive process, often requiring just the initial action of pouring hot water and waiting for the steeping to occur.

Common Curiosities
Can you make a decoction with tea leaves?
While possible, it's uncommon as boiling can destroy delicate flavors and compounds in the tea.
Why might someone choose a decoction over an infusion for medicinal purposes?
Decoctions extract more robust compounds from tougher materials, which can be beneficial for therapeutic effects.
What is the main difference between a decoction and an infusion?
The main difference lies in the preparation method: decoctions boil the substance, while infusions steep it in hot water.
Is an infusion always made with hot water?
Typically, yes, though cold infusions are also possible, especially for delicate teas or when making cold brews.
Are there any health benefits unique to infusions?
Infusions can preserve more volatile compounds and antioxidants that might be destroyed by boiling in decoctions.
Which method is quicker, decoction or infusion?
Infusion is quicker as it requires only steeping, while decoction involves prolonged boiling.
How does the flavor of a decoction compare to an infusion?
Decoctions are typically stronger and more intense due to the longer and more aggressive extraction method.
How can you enhance the flavor of an infusion?
Adding herbs, spices, or sweeteners can enhance the flavor of an infusion.
Can you reuse the same materials for multiple decoctions or infusions?
Yes, especially with tougher materials for decoctions, though the potency decreases with each use.
How do you know when a decoction or infusion is done?
For decoctions, it's often when the volume has reduced by a certain amount; for infusions, it's typically based on color and taste.
Is there a risk of over-extracting with decoctions?
