Make an infused essential oil

• Tea is a common example of an infusion; most varieties of tea call for steeping the leaves in hot water, although some variants (e.g. Moroccan mint tea) call for decoction instead. Many herbal teas are prepared by infusion, as well; lemon, chamomile, senna, apple, ginger, rooibos, and many other plants are used individually or in combination.

• Coffee can also be made through infusion (as in a French press), but is more often made through percolation.

• Herbal remedies are commonly produced through infusions in water or oil.

• Flavored oils: Plants with desirable flavors may be steeped in an edible oil or vinegar for an extended period; the infused oil or vinegar is often sold still containing the plant and is then used as flavoring. Chilis, lemon, garlic, and many other plants may be used. There can be ambiguity in the labeling of these oils: for example, what is described as sesame oil may be oil extracted from sesame seeds or another vegetable oil infused with sesame.

• Cucumber water, a mix of sliced cucumber with citrus slices and herbs such as mint, is a popular infusion. It is sometimes known as “spa water” due to it being commonly served in day spas and similar personal care establishments.
