Traditional methods of nutrient extraction from plants have been practiced for centuries and are deeply rooted in various cultures around the world. These methods are often simple, yet effective, and rely on natural processes to release the valuable compounds from plant materials. Here are some of the most common traditional extraction methods:

3.1. Soaking
Soaking is a straightforward method where plant parts are submerged in water for a period of time. This process allows the water to draw out soluble nutrients from the plant material. Soaking is commonly used in the preparation of herbal teas and infusions.

3.2. Decoction
A decoction is made by boiling plant material in water to extract the nutrients. This method is particularly useful for hard plant parts such as roots, bark, and seeds, which require heat to release their active compounds. The decoction is then strained, and the liquid is consumed or used for further processing.

3.3. Maceration
Maceration involves crushing or chopping plant material and then allowing it to steep in a solvent, usually water or alcohol, for an extended period. This method is used to extract oils, resins, and other compounds that are not easily soluble in water.

3.4. Infusion
Infusion is similar to maceration but typically involves using hot water and a shorter steeping time. The plant material is placed in hot water, and the heat helps to extract the nutrients. This method is widely used for making herbal teas.

3.5. Fermentation
Fermentation is a biological process in which microorganisms, such as yeast or bacteria, break down plant material to release nutrients and produce new compounds. This method is used in the production of fermented foods and beverages, such as sauerkraut, kimchi, and kombucha.

3.6. Sun Drying
Sun drying is a simple and natural method of extracting nutrients by exposing plant material to sunlight. The sun's heat and UV rays help to break down the plant's cell walls, making the nutrients more accessible.

3.7. Smoking
Smoking involves exposing plant material to smoke, which can help to preserve the plant and extract certain compounds. This method is used in the preparation of some traditional medicines and in the smoking of herbs for culinary purposes.
